Autoflowering Cannabis Seeds Guide: Choosing the Right Strain To Grow

Autoflowering Cannabis Seeds Guide: Choosing the Right Strain To Grow

You can follow these simple steps reflected in our Autoflowering Cannabis Seeds Guide, and you will get a good harvest. Before continuing, we would like to give some tips that will help you avoid the mistakes that many beginners make. Not singles are less important. Many beginners commit them, thus losing months of effort, illusions, and money according to Cannabis Life Network. First of all, do not be stingy! We are perplexed when, continuously, we see how beginners spend a considerable amount of money on good seeds that they then grow in a hole they make in the middle of their land or garden. Never make that mistake! The weakest point of cannabis is its root system. Their roots are thin, in comparison with other species, and they need good soil; loose and fluffy. Neither uses the land of your garden. Do not buy the cheapest one. Get quality land. Let’s explore! 

Cannabis Species at a Glance 

To continue, never grow seeds whose origin is not absolutely clear. All too often we see novices who tell us that they are growing some seeds that a friend has given them, who, in turn, gave him another friend. They do not know the genetics or their state of conservation. The seeds of the best marijuana are quite cheap if we consider the quantity and quality that can be obtained if we do things right. Do not make elementary mistakes.  

All cannabis varieties are dioic, that is, they have male and female gender. And all types, with the exception of Ruderalis, follow a life cycle based on the photoperiod that exists in each phase. They germinate in spring; they grow during this season and until the beginning of August. And it is finally at the beginning of this month when they enter their final phase: flowering. Flowering is the phase in which flowers are formed, also called buds, and lasts until the death of the plant since cannabis is an annual plant. 

All cannabis strains have differentiated sex. That is to say, we have males and females. The females are those that “place” or those that have psychoactive properties. Therefore, unless you are a breeder (a breeder geneticist), you are only interested in females. Before all the seeds available were regular, that is, you could get males and females. It was a matter of luck. But for years you can buy feminized seeds a hundred percent. This gives you the guarantee of knowing that all your plants will provide you with marijuana. Because the grass that leaves the males have no psychoactive effects. 

If for any reason you have regular seeds, you should be careful and remove the males as soon as you detect them. Otherwise, they will pollinate the females. A pollinated female is filled with seeds. As you are not a professional, this does not interest you since a female plant full of seeds loses much of its psychoactive effect. In any case, this article is aimed at beginners. Being a beginner, We advise you to start cultivating feminized seeds. We go phase by phase. First, we will explain it as it happens in nature so that it is easier for you to understand how it is done indoors with artificial lights.

Photoperiod in Cannabis 

Cannabis, except for the genetic Ruderalis, depends on the hours of light to develop in each phase of your life. They begin their life in the spring and continue to grow as long as the days have adequate hours of light. When the month of August arrives, in the northern hemisphere, as the days are shorter, the plant begins, little by little, to develop flowers that later will become buds, which is what you smoke. That is, they are dedicated to growing (vegetative growth phase) when there are more hours of light. And they are dedicated to bloom (flowering stage) when daylight hours decrease. And so on until his death; although we harvest them before this happens. 


As we have said, we must differentiate between Indica cannabis and Cannabis Sativa. Indica varieties have a more relaxing, more narcotic effect. And in addition, they are harvested long before Sativas. On the other hand, they are more productive. 

Pure Sativas occur in the tropics, where the natural photoperiod is 12/12 per day. That is, every day has 12 hours of light and 12 of darkness. If you do not live in the Tropics, it is challenging to grow them since by the time there are less than 12 hours of light, it will be midwinter, and the plants will freeze. 

The flowering periods are also very long. For this reason, geneticists have been dedicated to obtaining Indica / Sativa hybrids to obtain plants that are harvested in much less time than a Sativa but still maintain their psychoactive properties. Never germinate your seeds to plant outdoors if the night temperature is still less than 16 degrees. 

Do not rush, wait in the middle of spring or until it is necessary and you will get the best results. 

Germination Process 

From the end of February to the middle of June you can and must germinate your seeds. For this, you have two methods and in both the water play an important role. Put water in a glass (try to make sure that the water does not have chlorine) and then put the seeds in it. You will see that they float. It is not a problem. 

After about 24 hours, you will see that many have gone to the bottom of the glass. Many tutorials say that those that keep floating do not work. This is not entirely true. When a seed remains on the surface, give a few nudges with a finger, and you will see that most sink. They are seeds that had not sunk because they had some oxygen inside them. But as soon as you help them with that little push, they end up sinking.  

But, if still pushing them down they remain on the surface, and then they are definitely unfeasible. Throw them and continue with the good ones. This is the first system. Other growers choose to put the seeds between two paper napkins or moistened toilet paper (moistened does not mean dripping water). A day later, you can move on to the second stage of the transplant. 

In both the first and second forms, it is common to see how the beginning of a rootlet begins to appear subtly. It is a great sign. Have the substrate prepared before transplanting the seed. Before putting the seed that you have previously wetted for 24 hours, it is essential to have the prepared substrate in the place where you are going to grow your seed. Once again we are faced with several options: pot or mother earth. In both cases, it is imperative that the substrate is of quality. If you cannot afford the prices of the substrates sold in the grow shops, at least buy a good one in your nursery.  

You must have the substrate prepared before putting the germinated seed in it. Ready means wet. Previously you have watered it in abundance and when the surplus water is removed, make a hole in the center of approximately one centimeter deep and the same width. Put the seed, cover it and wait. 

If you have opted for pots, put them in the sun, in its final place. If you have chosen mother earth, it is advisable to make a hole of about 50 liters of volume in the earth (somewhere in the sun) and then fill it with a suitable substrate. 

In both cases, in a couple of days or so, the small plants will begin to sprout. At first, they will be just a couple of cotyledons that, little by little, will become pairs of leaves. As the plants in this phase are so small, with that first irrigation you will have more than enough for days, probably more than a week. Never have the substrate puddle and water when at least the first 3 centimeters of it is dry. It is much worse to the sin of excess than of defect. 

Vegetative Growth Phase 

From that moment you will begin to see how your plants grow. The growth is exponential, not arithmetic. What does this mean? It means that the small plants, at first, are very slow. Three weeks pass, and it has barely grown a span. But as time goes on, they start to grow like crazy. If during the first three weeks they grew one span, during the next three they grow one meter. Do not despair at first thinking that they are too slow. It’s normal. 

The plants will continue to grow very rapidly until they reach their next phase, flowering. From this moment, although they will grow, more or less, depending on the different genetics, growth will slow down considerably. 

Flowering Phase 

In the northern hemisphere, the plants begin to bloom at the beginning of August. At first, they develop preflores at the intersections of branches and leaves. They are white hairs that, little by little, will turn into flowers (buds), full of trichomes and sticky resin. The buds are getting bigger and bigger until they reach their maximum. Afterward, they simply begin to degrade until the death of the plant. 

Harvest and Manicure 

When you cut the plants, the final idea is to hang them to dry. But first, you must proceed to manicure them, at least some minimums. In fact, you have to cut, with scissors, all the leaves, large and medium, so that they do not interfere in the drying process. Some manicure even the smallest leaves; those attached to flowers. Others leave because they usually contain some trichomes that can be extracted later to remove pollen.
