How is known the autoflowering strain are descendent of genetics called “Ruderalis” that is originally from Rusia and has the capacity of flowering independent of the hour of light. In other words, the autoflowering seeds are the genetics independent of the photoperiod and super easy to grow outdoor and indoor, special for beginner growers.
Autoflowering cannabis seed plants generally begin to flower after 4 or 6 weeks automatically and their buds are usually ready to be harvested after 45 to 55 days of flowering, depending on the genetics of each strain. For this reason, the autoflowering strain is one of the faster seeds for growers of all types like an enthusiast of the cannabis and commercial growers, if you look at a fast harvest, the
autoflowering cannabis seeds are perfect for you.
Today exist many autoflowering seeds and here in Blimburn seeds you have the biggest stock of this strain for growing in your outdoor garden, some of the most popular strains is; Grandaddy Purple Auto, Gorilla G4 Auto, Cream Auto between other. This type of strain is special for the growers that want to grow outdoor and in the summer session to have strong plants in a short time with great buds.
The best condition for growing autoflowering outdoor
You know that the autoflowering strain does not dependent on a light cycle for growing and flowering, but is necessary for the most possible number of light hours for having great plant and good yields. It is good to point out that the optimal hours of light for autoflowering are 20 and 4 hours of darkness in growth. While some specialists say that with 18 hours of light and another 6 hours of darkness during flowering, the plant feels comfortable.
It is good to say that the adaptability of autoflowering strains is remarkable, however, at Blimburn Seeds we recommend that you start growing your autoflowering cannabis seeds between mid and late spring. The above, because in this way your marijuana plants will enjoy a better temperature and more hours of light outdoors, on the other hand, you will prevent the last rains of the season from affecting the growth of the specimens, ensuring optimal development.
Growing in winter or summer?
It is necessary to adjust the levels of fertilizers and irrigation in hot summer climates, since the plants tend to consume more nutrients and therefore more water in order to grow and flourish correctly. Another important point is that you will have to apply techniques such as LST in order to promote good air circulation and prevent the appearance of pests and diseases in the plants, which are generally caused by excess humidity.
Now, if you are going to grow in winter, you must bear in mind that low temperatures will make your plant grow slower and probably smaller as well, you must add that the hours of light are less for the same reason the plant it will not reach its maximum performance point. In addition, it is good to point out that the temperature of the water is fundamental, since if you irrigate with water that is too cold that is below 10ºC, the roots of your plants can suffer and literally block or freeze, completely highlighting your specimens.
Regarding humidity, it is good that it is always at 60% since small plants prefer a little more humidity for their development, remember that excess humidity affects the seedlings since it prevents them from breathing and therefore from developing.
For this reason, we recommend using a thermo-hygrometer, a device that measures humidity and ambient temperature and also analyzes the humidity levels and temperature that the place where you want to grow outdoors will have on the internet, this will help you to have parameters and to be able to develop a cultivation plan to avoid problems in the future.
Space of growing
In general, the autoflowering plant no has a big development for this reason you do not need a big space between plant-like with the female or regular plant. Is recommended use pot of 3 gallons and a space of 35-40cm between every plant. If you want you can make a defoliation in the early stage of flowering for give more power to the top part and increase the size of the buds.
The top strain
First of all, we recommend Granddaddy Purple Auto because it is a super strain, mostly indica, super easy to grow and fast from germination to harvest. THC levels range from 16%-19% and flowering lasts 49-56 days. As a good indica strain, the ideal is to grow it outdoors during the summer, starting the process between mid and late spring. In addition, it is good to be attentive to the humidity levels in order to avoid losing the harvest due to possible fungi or diseases that the plant may suffer.
You can apply LST techniques to Grandaddy Purple Auto plants, to ensure that the air circulates in a good way between its branches. And so, obtain good harvests, ranging from 80gr-120gr outdoors, achieving maximum yields with complete plants of this genetics in quantities of 10 to 20 plants and up, for patios and gardens.
We emphasize that Gorilla G4 Auto is an explosive, fast and mostly sativa automatic, with a great effect due to its high THC levels that are between 18% – 24%, delivering fun, energetic effects with a relaxed finish. Another important point is that outdoors it only takes between 8 and 9 weeks from the time the autoflowering seeds of this genetics are sown until the day of harvest, especially for lovers of sativa strains of marijuana and who want fast harvests.
For those looking for well mixed flavors, Gorilla G4 Auto delivers buds with pine and fruit flavors, a real refreshing treat on your palate.

The life cycle is fast since from sowing to harvest it only takes 65 to 75 days and yields of 80-100gr outdoors, yielding yields of 80-110gr/plant outdoors. The buds develop good levels of THC ranging from 16%-18% and to top it off, CBD levels reach up to 1.5% making it genetics indicated for medicinal users.
Growing autoflowering marijuana plant step by step
Just like regular or feminized cannabis strains, autoflowering marijuana strains require some care and concern from gardeners when growing. That is why we leave you here a simple step by step so that you know how to grow your autoflowering cannabis plants outdoors, these tips, complemented with those already given, will make you a first-class breeder.
Step 1. Germination
The first step is to germinate the seeds, which sprout with their main root after 24 to 72 hours of starting the process. Next, prepare the substrate where the germinated autoflowering cannabis seed will be planted, and use fungi that help the development of the roots such as diatoms and mycorrhizas.
Step 2. Week 1-2
When the little seedling emerges from the ground and begins to absorb the first rays of sunlight outdoors, you must ensure that it does not suffer from light stress. Therefore, we recommend using some type of filters such as a mesh or similar so that the sun’s rays do not affect the plant in its development due to light stress.
It is important to point out that, in the first and second week, the most optimal thing is to irrigate the seedling only with water and the minimum dose of rooting agent to avoid over fertilization or a possible disease due to nutrition. Great roots of a young plant
Step 3. Week 3-4
Due to the above, it is that the substrate of the autoflowering genetics is well enhanced, rich in nutrients, and has fungi that help the development of the roots in the first phase of growth since all this enhances the optimal progress of the plant.
Then in week 3-4 the plant is already stronger, so you can start watering with the fertilizers and stimulants you want, keeping in mind that it is important to use the minimum or average doses in relation to the amounts recommended by each brand of nutrients. We say that, since balanced nutrition for each plant will depend on the genetics you have in your garden and also by using minimum or medium doses, avoid over fertilization problems or your plants suffering from a disease due to excess fertilizers.
Step 4. Week 4-5.
In this period, you will see the first pistils appear and the flowers begin to form. It is important to keep temperatures and humidity controlled, but since you grow outdoors this becomes impossible.
Buds affect by botrytis
However, you can apply some tricks to help you keep your outdoor crop in good shape, for example; water the plants in the morning to avoid the faster evaporation of the water when it is hot also, you can use a protective stimulant for the roots and another to avoid stress and thus you will take care of the autoflowering plants in the hours that the temperatures are higher and the lowest humidity. Also, you can apply some supplements rich in silica, which will make your plants more resistant.
Step 5. Week 7
When you reach week 7 and you are growing outdoors in the summer season, it may be possible that the plants are affected by mold or mites, for the same reason, it is good that you maintain preventive control over your crop, constantly checking it to avoid that the buds are damaged by some disease. If you want to carry out biological control, you can use ladybugs because they are your great allies to eliminate different types of mites and insects.
If we talk about mold or botrytis, you can preventively apply some to the substrate that will help you avoid having these types of problems. It is possible to name the “bacillus subtilis strain QST 713” fungus that prevents the spread of botrytis spores and is very effective against powdery mildew, as well as the “bacillus pumilus strain QST 2808” non-pathogenic fungus that takes care of the proliferation and spread of botrytis spores and that, protects your plant for up to 14 days from its application to the soil or culture substrate.
Step 6. Week 8-9
It is time to flush the plants to remove excess fertilizers or salts from the substrate where the plant is grown. For this, it is good to stop applying fertilizers and irrigate only with water, which allows the plant to feed in the last weeks with the nutrient reserves that are scattered throughout the substrate.
In the market there are different flushes indicated for this task and there are also different root washing techniques which can be used to obtain buds with a rich flavor and smoke. Cannabis plant washings can be done 2 or a maximum of 3 times about 2 or 3 weeks before harvesting the plant. You can apply defoliation in the lower and middle part of the plant to eliminate those leaves that are withered, dry, or have a yellow color, this helps the plant so that its upper tips finish flowering in a better way.
Step 9. Week 10-11
In general, autoflowering plants have a complete life cycle that goes from 8 to 10 weeks, therefore, in this tutorial, we will tell you that it may take an extra week, which we call number 11. At this time, the plants are already ready to be harvested, it is important to see the signs on the leaves such as; the color, and also analyze the color of the pistils and especially of the trichomes, which tend to turn brown.
The trichomes are the great indicators that the marijuana plant is ready to be harvested since they go from a transparent white color to an intense brown, that is when many gardeners prefer to harvest. After this comes the trimming of the cannabis, drying, and curing.
You already know how to start cultivating your autoflowering cannabis strains in the best way, now you only have to start sowing to expect a great harvest in a few weeks. See you in the next blog and remember that practice makes perfect, so you can continue learning with our blog and practicing in your garden to harvest the most incredible plants you have ever had.
