Before you start growing marijuana indoors, there are some key things to keep in mind:

Make sure that growing marijuana is legal in your state or city. In some states in the US, the cultivation of marijuana for recreational or medical use is permitted, while in others it is prohibited. Obtain all necessary permits and follow local laws and regulations. If you are growing marijuana for medicinal purposes, you may need a prescription from a doctor and special permission. Prepare your grow space.

You will need a place with light, ventilation and an adequate irrigation system. You should also consider security and privacy.

Seed germination for indoor growing

To germinate your cannabis seeds, you will need a small container with moist soil or a soilless germination method, such as using a wet wipe or the toilet paper roll method. Place the seed in the container with soil or on the wet wipe, and cover with a thin layer of soil or keep the wipe wet. Make sure to keep the temperature between 21-27°C and the humidity between 70-90%. The seeds should germinate in a few days.

Seed Germination

There are also gardeners who germinate the seeds by immersing them in water and applying some temperature, which stimulates the appearance of the main root, although from here we do not recommend this technique very much, since the embryonal interior of the seed can drown.

And finally, we tell you that there is the classic marijuana seed germination technique with 2 plates and napkins, in which the seed is placed on wet napkins inside the 2 plates (one on top of the other). After 48 or 72 hours you will have germinated the seeds.

Transplanting to larger pots

Once the seeds have germinated and the first true leaves appear, it is time to transplant them into larger pots. Be sure to choose pots with enough room for the plant’s root system to have room to grow. Use a soil specially formulated for growing marijuana, and add fertilizers as needed.

Growing Indoor

A good way to start growing is in small containers such as the plastic cups with which you play BeerPong. Then, when the plant has already developed a consistent root network, it can be transplanted into a larger 1.5 pot, and then transferred to a 4 gallon pot or larger, in case you want to grow a monster plant indoors.

Light and temperature control

Marijuana needs a large amount of light to grow properly. In an indoor grow space, you can use special lamps to provide the right amount of light. Make sure the room has a suitable temperature, between 21-27°C during the day and around 18°C ​​at night.

In case you grow indoors in the summer season and if your area of ​​the USA has very high temperatures, it is best to illuminate the grow room with LED lights to lower temperatures. And also, provide a good space for each of the plants to ensure the circulation of fresh air.

Light Cycle Control

Marijuana needs a specific light cycle to grow properly. During the growth stage, they need 18 hours of light and 6 hours of darkness. During the flowering stage, they need 12 hours of light and 12 hours of darkness. Be sure to follow this light cycle for healthy, productive plants.

However, if the crop is autoflowering cannabis strain, it is advisable to apply a lighting cycle of 20 hours of light and another 4 hours of darkness. Although autoflowering genetics grow and flower regardless of the hours of light provided, the previous cycle is recommended for success in indoor cultivation.

Irrigation and fertilization

It is important to keep the soil moist, but not waterlogged. Use a drip irrigation system to provide a constant watering and ensure that the soil stays moist without over-watering. You should also use fertilizers to provide your plants with the necessary nutrients. Follow the fertilizer instructions and adjust the frequency and amount of fertilizer as needed.

Control of pests and diseases

It is important to keep your growing space free of pests and diseases. Check your plants regularly for any problems and treat them immediately. Use organic or chemical products as necessary, always following product instructions and protecting yourself and your environment.

Organic pesticides and organic pest and fungus controllers are safe and sustainable options to protect your marijuana crop from pests and diseases. These products are made from natural ingredients and do not contain synthetic chemicals, making them safer for human consumption and the environment.

Control of pests

Some examples of organic pesticides and organic pest and fungi controllers for growing marijuana are:

Neem Oil: Neem oil is an organic pesticide that is made from the seed of the neem tree. It is effective in controlling pests such as bed bugs, mites, and aphids.

Garlic Oil: Garlic oil is an organic pesticide that is made from ground garlic and vegetable oil. It is effective in controlling pests such as bedbugs and whiteflies.

Coconut Oil Soap: Coconut oil soap is an organic pesticide that is made from coconut oil and caustic soda. It is effective in controlling pests such as bed bugs and aphids.


When the plants have reached the right size and are ready to harvest, cut the branches and hang them upside down to dry. Let them dry for a few days until they are dry and hard to the touch.  As you may already know, the color of the trichomes is a good indication of when to harvest marijuana. When the trichomes are transparent or white, it means that the marijuana is not yet ready for harvest.

If you notice that the trichomes begin to change to a yellow or gold color, it means that the marijuana is almost ready for harvest.

Cannabis Harvest

However, if you want a more sedative and relaxing effect, you should wait until the trichomes are dark brown or black. This means that the marijuana has reached its optimum maturity and is ready for harvest. It is important to note that the color of the trichomes is not the only indication of when to harvest marijuana.

You should also take into account the size and appearance of the flowers and the life cycle of the plant. With a little practice, you will be able to determine when to harvest marijuana for the best yield and quality.

Dry cannabis

Marijuana drying is an important part of the cultivation process, as it affects the flavor and quality of the final product. Drying is also necessary to remove excess moisture from freshly cut flowers, which helps prevent mold and other keeping problems. There are several ways to dry marijuana, but the most common way is to hang the branches upside down in a cool, dark place for a few days. Make sure the place has good air circulation and keep the temperature between 21-27°C.

Dry Cannabis

Another way to dry marijuana is by using a dehumidifier. This can speed up the drying process and help control moisture. However, you must be careful not to dry too quickly, as this can affect the quality of the final product.


Once the branches are dry, it’s time to cure the buds. Place the buds in a container with a lid and store in a cool, dark place for a few weeks. Open the container once a day to allow air circulation and keep the humidity at a proper level. After a few weeks, your buds will be ready to smoke.

There are several ways to use glass containers to cure marijuana

Glass containers with lids: These are a good option for curing small amounts of marijuana. Be sure to use glass containers with tight lids to lock in moisture and aroma. Open the container once a day to allow air circulation and prevent mold growth.

Glass Containers for Weed

Glass jars: Glass jars with tight lids are also a good option for curing marijuana. Be sure to use glass boxes with enough space so that the flowers do not crowd together and can dry properly. Open the box once a day to allow air circulation

Among all the existing cultivation techniques, we recommend that you use LST indoors to stretch its lateral arms and you can even occupy it in the central stem, bending it downwards from the tip in case you want to enhance the growth and flowering of the lateral branches. so that they produce buds as if it were a central stem.

Green Crack x Super Silver Haze

This variety has a flowering time of approximately 8-10 weeks, although it is always good to wait an extra 1-2 weeks in flowering to get optimally ripe buds. Additionally, Green Crack x Super Silver Haze can produce up to 1.62/ft2 when grown indoors.

Green Crack x Super Silver Haze strain

Green Crack x Super Silver Haze has an energizing and cerebral effect, making it a good choice for daytime smoke. It has a tropical flavor with an aftertaste of fresh mint and earthy notes. This variety is suitable to be grown both indoors and outdoors. However, it excels in indoor cultivation due to its relatively short flowering time and higher yields in controlled spaces.
