Growing autoflowering cannabis varieties


How to grow autoflowering seeds? i know sometimes it can look complicated, especially because we have some uncertainty about the final production, and we do not know very well the type of substrate to use, the amount of nutrients to provide, and more importantly, its lighting, both in outdoor and indoor crops, being key its flowering time, something that will depend largely on its genetics.


That’s why, in this blog, we’re going to give you some notions of its strains, to understand the basis of its development, flowering and morphology




📖 Introduction


Most of the autoflowering marijuana seeds on the market contain a certain genetic load of the native variety of Cannabis Rudelaris L. a genotype originating in the northern Himalayas and some of the southern countries of the former Soviet Union


Its phenotype shows a weak morphology, sometimes confused with a low quality weed, so that it has never been developed as a variety of narcotic cannabis, not even for the production of fibre, since they are also small, thin-stemmed, low-foliage plants.


You can see it growing wild in cold and steppe areas of northern Europe, such as Lithuania, and adjacent regions.


Cannabis can be classified into three categories: indica, sativa and rudelaris.

Cannabis can be classified into three categories: indica, sativa and rudelaris.


Until now, a variety that is not very interesting because of its low agronomic value, except for one thing: its genetics don’t care about a whistle that has almost no solar radiation, its only reason for being is to reproduce, and for this reason, it starts flowering in the worst conditions, cold and little solar radiation.


How is the Cannabis Rudelaris L. variety different from the autoflowering seeds that we can now find on the market?


In A lot!!!



✅ Differences between the cannabis variety Rudelaris L. and autoflowering seeds


The current autoflowering seeds are hybrids of narcotic cannabis but with a certain Rudelaris charge that has been preserved in its only interesting feature: Autoflowering.


Although it is also true that some more than others, since genetic hybridizations are never perfect, and that results in some varieties result in small plants, dwarf type, although others delight us with monsters of more than a meter, with large size and considerable psychoactivity.


The plants that are very fashionable lately that you will know as “Fast version”, are hybrids that have been reducing the genetic load Rudelaris in successive crosses, giving plants that, although not purely autoflowering, are very sensitive to the hormonal changes that involve flowering, blessing you with a great harvest in less time than a feminized or regular variety typical.


Growing autoflowering correctly means that in about 2 weeks it will start to flower (in 3 at most) and from that moment on, your harvest will be ready in 9-10 weeks


A bad root development at the beginning will end up leaving the dwarf plant, stagnant in growth and with a scarce production, therefore, the first two weeks are key.



✨ Tips for growing autoflowering seeds


These are the premises you must follow to successfully grow autoflowering seeds:


* Promote seedling root development

Use a root stimulant at a minimum dose immediately after the seedling has been placed in the pot. Use pots of at least 10L.


* Highly spongy substrate

It uses a substrate that allows rapid root development. The root of an autoflowering marijuana plant will ask you for speed, for this requires little resistance to growth, with spongy substrates that allow the root to be well oxygenated. A balance of peat, coconut and perlite is ideal.


* Humid but not wet substrate

Try not to let the substrate dry out completely. If any radicles get dry and yellowish you will leave your plant small.


* Fertilizer with nitrogen

Use a fertilizer with a nitrogen base from the second internode onwards in minimum doses.


* Fertilizer with phosphorus

Continue with the nitrogen fertilizer (growth) and supplement it with phosphorus once the plant has started flowering.


* Make sure that the chosen genetics are of good quality

See how other growers are / have been growing and how that variety turned out.


* Lots of light!

Since it has its first pair of leaves, if it is in an indoor crop, we put it under a high intensity spotlight at least 20 hours of light and 4 hours of darkness. A 400W HPS is a good lamp, but if you feed it with an LEC, much better. If what we want are small plants we will regulate the effective intensity of light by moving the focus away from the plant so that it does not reach so many lumens.


* Autoflowering plants don’t like transplants

In transplants the root is always damaged in some way, so a plant that requires a very healthy root for its rapid development better not to touch it.



⭐ Self-cultivation recipe for autoflowering varieties (potted pot)


  1. Cut off the bottom of a “cup” or a 7-10cm pot.
  2. Place 5cm of coconut: wet perlite in the bottom of a 10 litre pot.
  3. Fill the wide part of the 10 litre pot with coconut perlite (dry)
  4. Bury the 7-10cm cup or pot halfway down in the 10 litre pot. Fill this with coconut-pearlite as well.
  5. Now plant your sprouted seedlings in the cup and water in the usual way.
  6. When watering your autoflowering plant, be sure to water ONLY in the small pot for the first 10 – 14 days. This will ensure that the seedling receives the water it needs (and depending on its age, the nutrients as well).
  7. Meanwhile the main root of the car will grow downwards, an accelerated growth outside the wet coconut-pearlite layer, just know that it is in the bottom of the 10 litre pot.
  8. The main root sends an extensive network of smaller root hairs that also seek that water source.

🚀 Cheer up, it’s simple!


This method for the correct development of an autoflowering plant makes your plant grow with a healthier root system, which will increase the size of your plant, and therefore the yield of your final crop.


It also avoids the shock of transplanting it could give its roots and leave your plant tiny.


We hope it has been helpful, and you can enjoy the success of a good autoflowering strain. Autoflowering growing turns to be much easier!
