Indoor Cannabis Cultivation

For both recreational cannabis enthusiasts and individuals seeking its medicinal benefits growing indoor cannabis today is super easy and popular. Growing indoor cannabis today is one of the most popular activities between the members of the weed community.

Once you grasp the fundamentals of nurturing cannabis plants in your own space, the rest becomes second nature with continued practice. It’s not a complicated skill to acquire and offers a amazing experience.

Speak to any experienced cannabis grower, and you’ll see their magic of the home growing cannabis. There’s much to appreciate, from the daily tranquility of tending to your indoor cannabis garden to the satisfaction of experimenting with various training techniques.

Discover our extensive catalog with more than 970 varieties, feminized, autoflowering, high thc. Stable genetics and easy to grow indoors or outdoors.

Why Indoor Cannabis Cultivation is on the Rise

Some of the reasons that explain why growing cannabis indoors cannabis is one of the most popular methods today, we will tell you below:

Personalized control: Establishing an indoor cultivation space empowers you to finely manage specific elements that are ideal for your selected cannabis strain. Taking charge of factors such as temperature, lighting, humidity levels, ventilation, and nutrient provision results in healthier, more prolific yields.

Elevated quality: Indoor cannabis varieties often boast superior quality, heightened vibrancy, and increased potency, offering enhanced flavors and a greater abundance of trichomes.

Indoor Cannabis Cultivation

Weather resilience: If you happen to reside in an area unsuitable for outdoor cannabis cultivation, indoor growing shields your crops from adverse weather conditions such as storms, strong winds, heavy rain, and extreme temperature fluctuations.

Reduced risk of pests and diseases: Certain top-notch indoor strains exhibit enhanced resistance to pests and diseases. Maintaining a clean, sterile environment indoors can further minimize the likelihood of encountering these issues.

Consistent year-round harvests: Cultivating cannabis indoors enables year-round harvesting, as you are not dependent on seasonal changes.

Increased THC Levels: One of the most significant benefits of an indoor operation is the ease of introducing more carbon dioxide into the environment. CO2 levels in grow rooms can be manipulated to ensure optimal growth and yield, often resulting in higher THC levels.

Enhanced Security: An indoor location that can be securely locked down is often easier to manage and monitor in terms of security compared to an open field. Some state security requirements mandate personnel and equipment to digitally and visually oversee plant inventories and technology, which can be a much more challenging task when dealing with a widely spread crop in an outdoor setting.

Setting Up Your Indoor Cannabis Garden

Establishing an indoor marijuana cultivation system in your residence is simpler than you might imagine. While it does involve an investment of both time and money, assembling the necessary materials and constructing it doesn’t demand significant expertise and can be accomplished inexpensively.

This guide will demonstrate the process of creating three distinct indoor cannabis garden setups at varying price levels. Each of the constructions outlined below includes all the essential components required to create a straightforward, climate-controlled environment for your marijuana plants.

All the equipment required for these projects can be easily purchased online or acquired from a local hardware store or specialized grow shop.

Setting Up Your Indoor Cannabis Garden


Choosing the Right Location

Now achieving success in indoor cultivation lies in meticulous planning. You can have superior results and long-term cost savings if you invest extra time in planning can lead to. . The first step is to start by creating a comprehensive floor plan for your chosen room for growing.

Is important to have a room with the right temperature. If possible, having access to an exterior wall or door for ventilation can simplify the process. The  position of the  lights and plant containers or beds is a principal point for a great growing process. We recommend using adjustable chains to hang your lights, ensuring they maintain an optimal distance from your plants.

Selecting the Ideal Grow Room Size

The Importance of Lighting

The photoperiodic plant necessitates specific light requirements during different growth stages. In the first stage,  the vegetative phase, a consistent light schedule of 18 hours on and 6 hours off is commonly employed when starting from new seeds or maintaining mother plants or clones in this state. However, when it’s time for flowering, the light cycle transitions to 12 hours of light and 12 hours of darkness.

For growing indoor cannabis the  light and dark cycles, particularly during the flowering phase. If the cannabis plant suffers an interruption in the expected nighttime conditions can lead to a bad production of buds or lost the opportunity of an amazing harvest.

Another point relevant is that the plant feel stress if  the light system is not regular with the hour and the plant shows different problems, for example a poor development. Having a  dark room for growing cannabis is  a priority.

Is necessary to evaluate whether your plants might be exposed to ambient light from sources such as doorways, windows, or exterior cracks. To address this, take a moment to observe the room in complete darkness and check for any sources of light leakage.

Use a home system to cover any visible light sources, and pay close attention to the possibility of glowing power strips, digital clocks, or any other devices emitting passive light.

LED vs HID Grow Lights

When the LED grow lights were introduced to the market the growers of cannabis start  a discussion if are  better that the classic HID classic lights. The response to this question varies based on your objectives.

To determine the most suitable option for your needs, it is beneficial to examine the technology underpinning LED grow lights when compared to HID grow lights. When evaluating HPS and LED grow lights, it is also essential to take into account other types of HIDs, such as MH and CMH lights.

LED vs. HID Grow Lights

Light Spectrum and Intensity

This are two different technologies represent two distint style for produce light. HID bulbs enclose inert gas inside their glass housing, while LEDs operate on solid-state technology.

The HIDs generate a substantial amount of heat, with a significant portion of their emissions falling within the infrared (IR) and ultraviolet (UV) spectrum. LEDs emit light within a narrow segment of the visible light spectrum and use energy efficiently without generating excessive heat or non-visible electromagnetic radiation.

This complex topic becomes even more intricate due to the existence of various forms of light radiation. Light sources emit energy across a spectrum of light, which is quantified by different wavelengths. Human vision is limited to perceiving only a portion of these wavelengths, rendering those beyond our visual range essentially ineffective for practical purposes.

High-Intensity Discharge (HID) lamps not only exhibit lower luminous efficacy but are also restricted to emitting light within the visible spectrum perceivable by the human eye.

In contrast, Light Emitting Diodes (LEDs) excel in energy efficiency while significantly enhancing the quality of light output. Consequently, LEDs require fewer lumens (approximately one-third less) compared to HIDs to deliver superior-quality illumination. This concept is commonly referred to as lighting efficiency, or sometimes, wall-plug efficiency.

Some LED lights say that produce less lumen than a HID Light, this point is possible. However, it’s important to note that the lumens emitted by LEDs are much more valuable because they fall within the range detectable by the human eye. On the other hand, the HID lights can produce more lumens but are not views by the human eyes and note are of high quality.

Ventilation and Airflow

Fresh air is important for cannabis plants primarily due to the process of photosynthesis. Adequate airflow plays a principal role in optimizing the photosynthesis efficiency of your cannabis plant, because the plant  converts light, carbon dioxide, and water into essential nutrients.

Through respiration, the cannabis plant obtains oxygen and glucose to generate energy, this causes the plants to have healthy growth and the development of robust and strong buds. This process is essential in the vegetative season and in the flowering time of the plant.

Ventilation and Airflow

Furthermore, carbon dioxide is a vital requirement for your plant’s survival. Stale air can lead to a depletion of carbon dioxide over time, potentially suffocating your plant. To avert this, proper ventilation becomes indispensable, simulating the natural outdoor air circulation.

Moreover, inadequate air circulation can result in carbon dioxide accumulating in some areas while other parts lack the necessary concentration, leading to uneven growth and reduced yields. Hence, effective air circulation ensures even distribution throughout your growing space.

When the grow room does not have fresh air or a well-ventilated growing environment, your plant could be at risk of starving because it does not have the ability to absorb the necessary nutrients it obtains from the soil or through irrigation. The above makes processes such as photosynthesis and respiration, which are vital for their survival, difficult.

Proper Air Circulation

This is one of the first steps, that is, making sure you have adequate air circulation. For this it is necessary get some exhaust and intake fans, relative to the size of the grow room. The fans in conjunction with the appropriate extractors will ensure adequate air circulation in the crop. Furthermore, if we add filters that help remove dirty air, you will have the holy grail of ventilation.

 Importance of Carbon Filters

The cannabis plant possesses a distinctive aroma, but not everyone finds it appealing. Therefore, in order to conceal its scent, the use of carbon filters is necessary. Carbon filters are so important in the ventilation system of a cannabis cultivation room.

The filter is an effective way to eliminate unwanted odors and gasses from the atmosphere, thus maintaining a clean and fresh environment within the grow room.

Carbon filters operate by utilizing activated carbon, a form of carbon treated with oxygen to create numerous tiny pores between carbon atoms. These pores has the capacity for  absorbing all the gasses and odors that produce the cannabis plant in the room.

When air passes through the carbon filter, this activated material absorbs these unwanted molecules, trapping them within its pores. This process removes dirty air with bad odors and gasses, resulting in cleaner, fresher air discharge from the filter.


All time is necessary to select the appropriate size and type of carbon filter in relation to the size of your grow room. The filter size responds to the medition to the CFM (Cubic Feet per Minute) rating of your exhaust fan, ensuring thorough and effective air filtration within the grow room.

Replaced periodically the carbon filter is necessary because the carbon becomes saturated over time, diminishing its effectiveness. Carbon is a dense material—just one gram of it boasts a surface area of 3000 square meters—making even smaller carbon filters highly effective at masking the scent of cannabis.

Temperature and Humidity Control

Cannabis plants require two essential factors: humidity and temperature. In the case of temperature, it is so important that you can have a grow room with the best system but if you do not regulate the appropriate temperature, everything will be in vain.

You can create a fantastic environment for your plant, but it still won’t work if the temperature is not in the right range. For their part, cannabis plants require temperatures similar to those of humans, therefore, exposing them to temperatures that are too high or too low should be avoided. In relation to the environment, it cannot be too humid or too dry, just a balance similar to what people need.

Ideal Temperature Range

There are different temperatures for cannabis plants depending on the moment they are in. For this reason, you must imitate the temperatures in the growing location as they occur in the natural environment.

Now, an acceptable temperature range for weed plants is between 20°C and 28°C or between 68°F and 82°F when the lights in the grow room are on. When it comes to nighttime temperatures, cannabis plants prefer slightly cooler temperatures. Below we share the relevant information about the temperatures for each phase of plant cultivation.

Warmer temperatures are perfect for weed seedlings and should range between 20°C and 28°C or 68°F and 82°F. Additionally, breeders must ensure that the humidity is not low.

The specimens can be seedlings or young plants, and they will be in a vegetative state. This point is of real importance in non-autoflowering plants, since their light/dark cycle is usually established at 18 hours of light and 6 hours of darkness.

As we already noted, cannabis plants grow optimally in slightly warmer temperatures, ideally between 20 °C and 28 °C (68 °F to 82 °F) during the phase described above.

Ideal Temperature Range

However, when plants are in a more advanced vegetative phase they can withstand higher daytime temperatures, ranging between 20 °C and 30 °C (68 °F to 86 °F). Although, care must be taken if temperatures exceed 28°C, because poor ventilation can generate stress in the plants, subsequently causing problems in the crop and harvests.

For flowering, cannabis plants must have a temperature range of 18°C ​​to 26°C (65°F to 80°F), which allows optimal development of the buds. Although also, with lower temperatures in that range, larger buds can grow and in addition, the production of terpenes improves, which generates buds with denser structures, the explosion of other colors and somewhat more intense aromas.

Some growers lower the temperatures indoors to induce purple colors in the plants, therefore it is recommended that they be decreased between 8 °C and 10 °C when the plants sleep, a technique that can be useful with some specific genetics.

On the other hand, high temperatures above 28°C can cause a decrease in potency, cannabinoids and evaporate terpenes. If you want to have healthy buds, it is best to maintain temperatures between 18°C ​​and 27°C during the day, and at night decrease to at least 15°C.

Managing Humidity Levels

Humidity control when growing cannabis is vitally important for plants. Generally, cannabis plants in the growth phase benefit from more humidity than when they enter the flowering phase.

Although these are generic data, it is important to keep in mind that it depends on the genetics being grown to apply certain humidity levels. Here at Blimburnseeds.com we usually sell mostly hybrid genetics since they have a part in their genetics of indica and another of sativa, therefore, it is necessary to study each strain to determine what levels of humidity they require.

Sativa genetics, due to their more open structure and spongier buds, tend to withstand humidity better. In relation to trend varieties, it indicates that, being more compact, they are more likely to be affected by fungi such as mold, which is produced by the high humidity. Between 55% to 65% humidity is recommended.

Managing Humidity Levels

Seedlings: In the case of young plants, a humidity of 65% to 70% is recommended. While the temperature should be maintained between 20 °C to 25 °C, with a minimum dark period temperature of 20 °C.

Vegetative Stage: Plants in this phase are already developing, therefore, humidity can decrease between 55% to 65%. For its part, the temperature can rise gently between 26 °C and 28 °C during the day and not less than 18 °C at night.

Flowering stage: Cannabis plants typically perform better with lower humidity levels during flowering to avoid mold problems. While there is no perfect range, it is advisable to reduce relative humidity to around 40% to 55%, favoring the lower end during late flowering. Temperature ranges between 20°C and 26°C are suitable.

Selecting the Best Cannabis Strains for Indoor Cannabis Growth

The individual preferences and objectives of each grower are the main influence in obtaining the best cannabis seeds for indoor cannabis cultivation. Some cannabis genetics such as autoflowering strains are perfect for beginner growers since there is no need to change the hours of light and their compact size and speed make them easy to grow.

Regarding, feminized cannabis seeds are ideal for those people who do not want male plants in their indoor cannabis cultivation.

The primary characteristic of feminized seeds is that they deliver female plants, ensuring good harvests. And last but not least, regular weed seeds will deliver female and male plants, with the latter you can select parents for the breeding of new specimens or genetics. But to ensure great buds and good harvests, the separation of male plants from female plants is required, so that the former do not pollinate the female plant.

Preparing Your Growing Medium

Cannabis breeders have different means when it comes to growing depending on their operation. The choice of growing medium will depend on the interest of each grower, some prefer to grow in hydroponics and others in the classic way in substrate.

Growing Cannabis

Here are the ingredients and equipment you will need, along with instructions on how to do it.


2 large bags (2 x 40 liters) of base soil or the equivalent in homemade compost. Between 5 and 10 kilograms of organic earthworms.

1 kilogram of blood meal.

1 kilogram of bat guano.

1 kilogram of vaporized bone meal.

750 grams of rock phosphate. ⅛ cup of Epsom salts. ¼ cup of azomite. ½ cup of dolomite. 1 tablespoon of powdered humic acid.

Equipment: Tarp. Rake. Shovel. Large plastic buckets or trash cans. With all of these elements at your disposal, follow the steps below to create your own super soil ready for use in the garden.

Start by clearing a spacious area in your garden or garage and lay down a large tarp to prevent material loss. Next, build a pile of base soil or compost in the center. Use a rake to spread a layer of organic earthworms on top and cover it with another layer of base soil. Then, add the bat guano and more base soil.

Continue adding layers of the super soil ingredients, followed by a final layer of base soil, until you’ve used all the components. Use a shovel to thoroughly mix the ingredients until you achieve a homogeneous substrate, which should take about 20 minutes (and some physical effort). Finally, load the mixed soil into large plastic buckets or trash cans for storage or use it immediately in your garden.

 Soil vs Hydroponics

There are several methods available for growing cannabis today. However, there are two forms of cultivation that are the most popular among weed breeders, which are soil cultivation and hydroponic cultivation. For these two methods, there are different techniques for their successful application, to ensure good production.

Plants grown in soil obtain from the substrate the nutrients they need, such as amino acids or minerals, and microorganisms help with this function. Unlike, in hydroponic crops the plants obtain nutrients from the water in which the roots live and expand and thanks to the periodic nutrition from which they benefit.

Both hydroponic cultivation and soil cultivation require certain specific techniques.

Soil vs. Hydroponics

For example: in soil cultivation you must begin by germinating the seeds and then sow them in the substrate for indoor cannabis cultivation or outdoor cultivation. Hydroponic growers, meanwhile, have a variety of options at their disposal, including deep water cultivation (DWC), ebb and flow systems, bubbleponics, aeroponics, and more.

Cannabis growing process

First of all, we must tell you that cannabis plants go through different stages during their life cycle where they require different amounts of water, light and nutrients, among other factors. It is good to know these phases of the cannabis plant in order to avoid making mistakes during cultivation.

Being clear about the cultivation processes is essential and here we are going to tell you what each of them is like and what you should do.

Germination and Seedling Care

The germination and seedling stage are two critical moments in cannabis cultivation, which is why in this part of the guide we explain it to you in depth because it is essential to have knowledge of this. Care both in germination and in the seeding phase is essential to ensure an optimal cultivation process and thus obtain great results.

Germinating Cannabis Seeds

Seed germination is one of the most important processes when growing cannabis. Germination begins when the seeds absorb the water that is applied to them for the explosion of the embryo that is inside them.

Once the embryo releases the first root, the cannabis seed can be placed in the substrate or in the medium used to grow. That is, germination is the process by which cannabis goes from seed to seedling.


Caring for Young Seedlings

When marijuana plants reach the seedling phase, you will see how the plant begins to produce the first leaves, showing a momentary maturation when it reaches between 5 and 7 leaves to continue its development in the vegetative stage.

Cannabis specimens are considered seedlings when they begin to develop the first fan-like leaves and when they have already developed all those leaves, it means that said time has passed. During this period, the seedlings do not require much water, so avoid overwatering to avoid damaging the roots.

Take care of the seedlings from excess humidity and avoid exposing them to fungi such as mold, among others. Also, you must make sure that it receives a sufficient amount of light.

In relation to the necessary lighting, we recommend that you start your indoor cannabis cultivation with regulated, low-intensity lighting when the seedlings are small and then, for a couple of weeks (3 or 4), provide the stable and continuous lighting that the plants require. to grow.

Vegetative Growth Stage

This phase begins when the cannabis specimens are small seedlings, which are attached to the seeds and after that, they are released from the shell, leaving only the 2 cotyledons visible. Through the cotyledons in the first days of life the plant is fed and then gives way to the appearance of the first leaves.

When the plant has passed the first weeks of life, the appearance of different arms and leaves is seen, which shape the structure of the plant together with the central stem.

As it progresses in its vegetative process, you will see how the leaves become larger, taking up a large space in the crop. For its part, the lateral branches become thicker and longer and the central stem spikes upward.

For this reason, it is good that in this phase different cultivation techniques are applied such as apical pruning, low-stress training, among others that we will explain to you later in this guide.

Providing the Right Light Cycle

Providing the Right Light Cycle

As is known, cannabis plants require certain light cycles in the case of photoperiodic plants. For their part, autoflowering plants grow and flower independently of light cycles. So photoperiodic genetics such as feminized, regular, fast version or F1 cannabis seeds require light cycles in the vegetative stage of 18 hours of light and 6 hours of darkness to have optimal development.

Although, it must be kept in mind that in the first weeks when the specimen is a seedling, it cannot be directly exposed to light because it will stress them out and put the entire growing process at risk. Therefore, it is good to leave them on the side of the grow room or protected under the largest leaves of mature plants in case you have other plants in the garden.

Now regarding autoflowering cannabis genetics, it is recommended to apply light cycles of 20 hours and 4 hours of darkness during growth and flowering. Remember that this type of plant does not depend on a photoperiod to begin to flower, on the contrary, they do so automatically.

Here we must also remember that at least during the first week of life the autoflowering plant must be prevented from being in direct contact with lighting in indoor cannabis cultivation or with the sun outdoors. The above is recommended to avoid stressing the plant since they are usually highly sensitive to lighting throughout the growing process, being easy to stress for this reason.

Pruning and Training Your Plants

It is during the vegetative stage of cannabis when the growth of the plants is expressed in all its splendor. It can last between 3 and 16 weeks, although normally indoors cannabis gardeners only usually give the plants between 4 and 5 weeks of growth to grow more. rapid.

Therefore, transplants can be carried out when the seedlings are barely between 2 and 3 weeks old. Now, if you want to do a longer crop you can take as a reference an average of 8-10 weeks for vegetative and carry out the transplant in week 4 or 5.

Pruning and Training Your Plants

Now to apply pruning techniques such as (FIM or Apical) and also Low stress training like LST should be expected between weeks 3 or 4 of growth. Some experts even take advantage of the last stretch of the plants at the beginning of flowering to optimize their crops, especially when techniques such as SCROG are used.

Flowering Stage

Since you change the light cycle from 18 hours of light to 12 hours of light and another 12 hours of darkness, it can take between 7 and 14 days for a weed plant to move into the pre-flowering stage. At this point, you can determine the sex of the plant by examining the preflowers located at the nodes. As the plant progresses towards the final flowering stage, it becomes easier to identify its gender.

When you buy feminized cannabis seeds at Blimburnseeds.com you should not worry about trying to determine the sex of the plants because these are 100% feminized and here we guarantee the high quality and stability of the genetics purchased in our store.

Now, if you buy the regular seeds that we have in stock at Blimburnseeds.com you must keep in mind that you must know how to differentiate between male and female plants.

In female weed plants, you will notice that they produce pistils (the reproductive parts of a flower) that grow in buds (flowers that develop on the leaves, with a cluster on each side). On the contrary, male cannabis plants, They produce small green sacs filled with pollen in the node areas.

Once the sacs of a male or intersex plant mature they open and release the pollen inside, pollinating nearby female flowers, potentially compromising the psychoactive potential of the buds of female cannabis plants. If you do not want to make a selection for new genetics or sexual reproduction of plants, we recommend eliminating the cannabis males from your crop.

 Triggering the Flowering Phase

As we already mentioned in the previous point, pre-flowering occurs before flowering and takes 1-3 weeks. After this process, the actual flowering phase begins. It is during flowering when the buds begin to develop and for that it requires a series of specific nutrients.

Now when the buds are fully developed, you can think about harvesting. This occurs approximately between week 8 to 10 of flowering, depending on the type of genetics you grow because in the case of the purest sativa-type cannabis varieties, flowering can take 10-12 weeks or even longer.

Triggering the Flowering Phase

 So, to determine if the cannabis plant is ready for harvest, observe the pistils of the cola buds, which will change from white to reddish orange, and the trichome heads, which will go from being transparent to a milky, opaque color and, finally, amber.

The amber hue means a higher ratio of CBD to THC cannabinoids in the resin. For this reason, the best way to harvest your cannabis plants is to see the trichomes on the flowers and leaves and these should have a cloudy white color, similar to when cloudy water comes out of the tap at home.

 Nutrient Adjustments

Firstly, prior to flowering, we recommend using a flowering stimulant that can be applied 10 days before the photoperiod change and throughout the flowering stage. This stimulant significantly enhances the formation and emergence of new buds, as well as the production of cannabinoids (resin).

To prevent nutrient saturation or over-fertilization, we advise minimizing and gradually phasing out growth fertilizers as the flowering stage approaches.

The second phase of flowering corresponds to the 3rd-4th week in 6-week flowering varieties such as autoflowering or fast version genetics, and from the 4th week onwards in 8-week or longer varieties, such as feminized hybrid, indica, or sativa-leaning genetics, including regular varieties.

During this phase, you can begin using products designed to bulk up the buds, such as PK-rich bud boosters. There is also the option to supplement fertilization during this period with additives known for their high content of natural carbohydrates and sugars, which increase flower density and aroma.

 Monitoring Plant Health

It is important to look at trichomes during flowering because they are responsible for producing THC, terpenes, flavonoids and other cannabinoids. As bud clusters develop, more cannabinoid compounds accumulate, causing the clusters to become resinous and sticky.

To keep the plant healthy at this stage and thus enhance the trichomes, you should try to have a clean growing room, free of all types of insects and pests that could harm the plant.

Monitoring Plant Health

Also, it is important that humidity is maintained at reasonable levels as indicated previously in this guide to avoid the appearance of mold and other fungi that destroy the buds of weed plants.

On the other hand, temperatures are super influential so that the plants do not stress and thus compounds such as terpenes that enhance the aroma and flavor of the flowers do not decompose, causing the loss of two essential qualities in cannabis specimens such as flavor. and aroma.

As the plants use a lot of energy in this phase, we also recommend watering with vitamins for weed plants that supply some micronutrients and specifically specific minerals that the fertilizers or nutritional supplements and even the substrate may lack, due to the wear and tear that they cause. suffers due to constant feeding of the plant.

Proper Harvesting Techniques

1- You can start by harvesting the plant, cutting each branch near the nodes (the area where the branches join the main stem). First cut the branches that do not have buds and then continue with the branches that do have buds and place each of them in a tray specially made for harvesting so as not to damage the flowers.

2- Another way to harvest is to cut the entire plant from the bottom of the central stem. This depends on the size of your plant. If the plant is small, it may be best to cut the entire plant at once and then trim the excess lateral branches.

Although, if the plant is large enough, it is best to harvest the side branches and then proceed with the central stem. If you want to cut the entire plant at once, it is best to do so about 12 cm from the soil or substrate you are growing in with a 45-degree cut.

Harvesting and Drying

To finish the cultivation there are two processes that are essential: harvesting and drying the buds. Each of these processes must be done with specific parameters and also following some steps to ensure success. Next we are going to see what those steps are and how to carry out a successful harvest and drying so as not to ruin the flowers we obtain from the crop.

Harvesting and Drying

Timing the Harvest

When you harvest plants too early, the THC will not have fully developed. And if you harvest them too late, the THC will have started to break down and turn into CBN.

Therefore, to get the maximum possible amount of THC and strongest effects, you must harvest at the right time! To know when to harvest, you must pay attention that when you buy marijuana seeds, each weed genetics has its technical information regarding the indicated time for harvesting.

 When you grow indoors cannabis, you have to keep in mind that it can be harvested after a few days of flowering, which is generally 60 to 90 days or it is also listed in weeks, which generally ranges from 8 to 10 weeks, depending on the genetics you cultivate.

For outdoor crops, you should consider that plants are generally harvested in late August or mid-September in the northern hemisphere. As we already pointed out previously, analyzing the istyles and trichomes with their respective colors is also an effective way and is probably the best way to determine when to harvest a cannabis plant correctly.

 Drying and Curing Cannabis Buds

The quality of the buds in terms of effect, flavor and aroma will also depend on the drying of the flowers. That is why here we are going to review some fundamental concepts to ensure great drying:

1- Flowers should be dried in darkness: That’s right, cannabis flowers should be dried in complete darkness, avoiding light at all times.

2- The place where the weed buds are dried should have between 60% and 65% humidity during the first 7 days. If the humidity is higher, we recommend using an activated carbon filter with an extractor to reduce humidity.

3- The ideal temperature is between 15°C and 18°C, because higher temperatures cause the terpenes to evaporate more quickly and in greater quantities. For this reason, sudden changes in temperature in the drying area should be avoided.

4- The air in the drying area must be renewed daily. Do not use fans or dehumidifiers or any other type of method to accelerate drying because it will cause degradation of the buds, causing them to lose flavor, smell, and even affecting the effects it may produce on users.

5- The buds should not lose more than 70% moisture. Avoid overdrying.

Marijuana buds are dried from the outer layers inwards. A good dose of patience is needed to guarantee optimal quality of your cannabis. That is why it is good that the buds dry for a minimum of 10 to 15 days. Accelerating this process can cause a loss of cannabis quality.

To see if the weed has dried correctly, you can gently squeeze a bud, which should feel dry on the outside but at the same time, with a low relative humidity inside without crumbling. If the flowers have a consistency flexible or elastic, continue drying them for a longer period.

You can also check that the buds are really dry if when you bend a branch it cracks and remains bent absolutely. However, if the branch does not crack and return to its original shape, give them a little more time to dry.

To dry the plant correctly, you can use the classic technique of cutting the plant at the bottom of the main stem and hanging it upside down from a cord or clothesline.

On the other hand, you can also hang the plant by its branches if you prefer or if the plant is large. In this way you will achieve a uniform drying process while preserving your buds’ natural shape because they do not have contact with any surface.

There are also vertical dryers and stackable dryers, however, first you must manicure your plants, to put them in the dryer without them touching. You should also move and rotate the buds every 2 or 3 days to prevent them from flattening or losing their shape when they come into contact with the mesh.

Curing marijuana buds can take 3 to 4 weeks depending on the ambient relative humidity and temperature of the curing site. With this time, it is guaranteed that the chlorophyll of the flowers degrades and that the THC goes from the acidic state (THC-A) to the psychoactive side that we like so much, that is, THC. Avoid exposing the buds to light during the curing period.

You can cure your buds without problems in airtight glass containers lined with some cloth or paper on the outside to prevent light from penetrating inside. You can also use wooden boxes which help absorb moisture from the flowers.

Be careful in the first weeks because the buds continue to release moisture, which can damage the harvest, which is why it is recommended to open the glass container or wooden box frequently and carefully, extract the flowers so they can breathe and release their moisture.
