Cannabis plants will unexpectedly revert back to vegetative growth if there is a disturbance in their photoperiod schedule—for example, if they receive 12 hours of light a day for a while, and then start to get more than that.
The re-vegging process is highly stressful on a plant and even if it does re-veg successfully, aberrations often occur, such as unusual leaf growth and hermaphroditism. Re-vegged plants are more delicate and must be given more attention and care.
Probably the easiest method, this will allow you to harvest a plant for buds and then re-veg it for a second growing season. This is typically done with indoor plants, as you’ll need to control the amount of light they receive.
Most growers who re-veg say that yields decrease the second time around. So while re-vegging may cut down on the amount of time it takes to grow a plant, it might not produce as much.
The process of taking a clone from a flowering plant is a re-vegging technique known as “monster cropping” (more below), and it can produce more vigorous and bushier plants. If done correctly, monster-cropped clones have the potential to create plants with higher yields the second time around because of an increased vegetative mass, stronger stems and branches, and more nodes for potential buds.
In this section, we’ll look at the pros and cons of re-vegging.
Although the science seems complex, re-vegging is actually pretty simple—and there are plenty of upsides to doing so!
Reduced Vegetative Period
Cannabis regeneration isn’t a one-size-fits-all process. In fact, there are a few ways you can kickstart a plant’s vegetative period—even accidentally.
Regeneration is kind of like hacking that biological process. While the original plant will eventually die, growers can first revert it back to its vegetative state. As a result, you can grow the same plant again for a second—albeit, slightly less fruitful—harvest.
Cannabis can unexpectedly revert back to its vegetative phase for a number of reasons, some of which are as seemingly insignificant as a light disturbance or weather changes. Because of that, accidental re-vegging is largely dependent on where you’re growing your plants, and any related factors.
Not everybody knows that after harvesting buds from marijuana plant, you can rejuvenate the plant and get another harvest from the same cannabis seeds! You can regenerate your plant and harvest it for the second time or sometimes even the third time. The process is not so complicated and it will save you money and time. Just think about it – instead of going to a seedbank to buy marijuana seeds, planting those weed seeds and investing time into growing them, you can reuse the plant that has already grown a good root system and a stalk. What’s great about is that the rejuvenated plants will be available for harvest in less than two months. However, to rejuvenate a plant you need to refrain from harvesting all the buds. Ideally you should cut buds only from the top 1/3 of the plant, while the rest of the buds should not be harvested. Some marijuana seeds growers can’t stop from getting more buds before the regeneration, but in general it is better to leave more small buds on the plant, otherwise the plant may wither. Cutting off more than a half of the plant will most likely kill the plant. Remember that it is essential to leave some buds, because without them the photosynthesis process cannot be done. After trimming the plant and leaving the most healthy leaves in the middle and lower sections, you need to put the plant back into vegetative stage.
While you rejuvenate your plant remember to provide enough nitrogen as without it the sun leaves will drop and instead of a new harvest you will have to buy cannabis seeds for a new growth. You should also put the plant into 24/0 light. Additionally, start out with mix of flowering and vegetative nutrients but give only ¼ of the usual amount . After a week double the dosage but use only vegetative nutrients. Keep the temperature balanced and water the plant lightly. Such treatment will result in a new leaf growth in one or two weeks. In some cases, this may take up to four weeks. Nevertheless, after you see the new greenery put your plant into flowering state. During the regeneration you will notice that the lower older leaves will grow first – don’t worry it’s normal. Thanks to rejuvenation you will get the lower buds fatter and grow some new ones, while waiting for the next marijuana seeds to grow.
As you need to put the plant under continuous light the regeneration process is more suitable for indoors. A good practice is to keep it separate not to risk pest infestation, especially when you rejuvenate outdoor plant inside. However, if you are growing cannabis seeds outdoors, it is possible to rejuvenate it outdoors during the summer months. Getting the first harvest in late June will allow you to regenerate your plant during the long days of July and August and then you will have your second harvest in Fall. There is an urban myth circling around the growers community which says that the weed from regenerated plants is not as potent as the one from the first harvest. This is not true, the potency of your weed depends on the way you grow your plant and the type of pot seeds you plant, regeneration does not influence the quality of cannabis.
