In this article we explore the not widely known technique of re-vegging your cannabis plants. Also, we show you the advantages and disadvantages of this method.

Most of us growers are used to cut down our cannabis plants once harvested because they ended their life cycle and provided us with fresh, beautiful and potent flower. However, it exists a method, which is not known and practiced by many, that can give you multiple harvests from one plant. Sounds a little strange, huh? This technique is called regeneration and basically means to revert your plant back into the vegetative phase (hence re-vegging). In some situations this can be very helpful, e. g. when you can't get new clones or seeds and have to use the same plant again for a crop of buds or a certain specimen showed really nice potential and characteristics so you want to get a clone even in flowering stage. Some may even have experienced re-vegging by accident when light leaked in during the flowering period - their plants started to revert into growth. We show you how to do it on purpose and what advantages and disadvantages you can expect.

HOW TO RE-VEG YOUR CANNABIS PLANT

First of all, re-vegging your favourite plants is no beginners technique. You shouldn't try this in your first grows because it can get real tricky and you always have to keep in mind that this method is very stressful and unnatural for your plants.

The regeneration of the chosen plant begins when you harvest the flowers. To put it back in the vegetative period of its life, you only harvest most of the buds. Keep the smaller leaves and flowers in the lower third of the plant and some larger fan leaves in the middle section. It should look like the plants skeleton when done right. It is hard to let the small popcorn buds on there but they are needed to stimulate the vegetative growth and don't really add something to the overall dry weight of your harvest. After that, you flush the roots and, if possible, have a look at them and prune all the defective roots.

Now, you can transplant to a new pot with fresh soil. You can put additional bacteria and additives to the soil mix if you like to further stimulate the re-vegging process. At this stage you will have to put your lady under 20-24 hours of light, so it goes back to the vegetative phase. Once it has fully recovered, you can switch to 18 hours of light, like you normally would. Your plant is in stress and shock mode now and will produce strange mutations in the first two weeks like round leaves. This is completely normal for the regeneration process and a more normal growth should start after about two weeks. This also means, that you have to be really careful with watering and adding nutrients because you don't want to overwater or overfeed your baby.

After a few weeks, your plant is ready to get into flower mode again. Trim back the strange leaves and give your experiment a little rest, then switch to 12/12 light cycle. This can save you time compared to a full cycle from seed to harvest.

POTENTIAL ADVANTAGES AND RISKS

The benefits of rejuvenating your cannabis plants can be plenty if done correctly; you don't need new seeds or clones, it can possibly save you time, the growth of a re-vegged plant can sometimes be bushier and this method can preserve specific genetics which performance you like. But you already noticed, how many "ifs" there are, right? Unfortunately, a lot can go wrong and usually regenerated plants tend to yield far less in every successive harvest, often show hermaphrodite tendencies, the quality and potency is reduced a lot of the times and the stress that comes with this process can also force the plant to take a long recovery (which eliminates the time advantage). Moreover, regeneration does not work with all strains and specimen of cannabis.

It's up to you if you decide to try this technique. Experienced growers can benefit a lot from re-vegging but you learned how many things can go horribly wrong. Maybe you see for yourself and try to rejuvenate one of your plants in the next grow round to witness the risks and potentials of this growing method on your own.
