In the absence of pretty much all of its leaves, it may be the case that all of the plant’s energy, now spare, is distributed to the buds instead. This may explain the explosive growth of the buds when plants are subject to such methods.
1.4kg) of weed under a single grow light. Schwazzing is a training method featured within the book that’s said to help growers achieve such barbaric yields.
Although this might appear shocking and damaging, it is said to pay off further down the line. The photoperiod should then be changed to a 12 hours on, 12 hours off cycle in order to induce the flowering phase of the grow cycle.
Schwazzing typically takes place twice within the grow cycle of a crop. The first bout occurs just before the flowering phase is initiated. The grower will remove the vast majority of fan leaves from plants, leaving them looking almost bare.
Schwazzing is a term used to describe an intense form of defoliation. The process involves removing many fan leaves from a plant, allowing much more light to pass through to bud sites.
The term schwazzing was born out of a book named Three a Light, penned by author Joshua Haupt. The very concept of the book is the application of various growing methods in order to produce a mammoth 3 pounds (
Well, the person in question might actually have a valid point. Something about severing off the fan leaves of your indoor crop during the flowering phase seems to rapidly ramp up the size and vigour of cannabis buds. Defoliation is the term usually assigned to the practice of clipping off a few leaves, but a new term has been developed for fully stripping a plant of its leaves, named “schwazzing”.
The removal of such large amounts of leaves will expose bud sites to light that previously would have been obstructed by the canopy.
Schwazzing then takes place for a second time 20 days after the initiation of bloom, roughly ⅓ of the way through the flowering phase. During this time, new fan leaves will have grown back, and in doing so, will have started to once again form an obstructive canopy, preventing large amounts of light from directly stimulating the buds.
Schwazzing may seem quite extreme, involving the removal of many leaves from a cannabis plant. Yet, it's said to boost yields by exposing buds to more light.
You can prune to change your plants’ shape, but never prune at the top to allow more light to reach the bottom; the top is always more productive than the bottom even if you want it to get more light. The logical thing to do would be to prune the bottom so that the top can produce even more.

We’re going to talk about a few different pruning situations, along with a picture and an explanation so that you know where you have to cut depending on the result you want, because not all pruning is done the same or for the same reason, so each type has a different effect on your plants.
To use this prune technique you’ll have to be a bit more careful, because you’ll have to cut along the fattest part of the trunk, and your plant will have an open wound that you’ll need to cover up. This way you’ll manage to get the plant to have a high density of flowers on the inner and outer branches, creating a blanket of buds of around 40x40cm with which you can fill a square meter grow tent with just four plants or a 1,2×1,2 grow tent with up to 9 plants. This kind of pruning helps spread out the production in the shape of smaller buds but in larger quantities. You’ll need to make the cut right around the height of the lower branches, leaving the plant looking kind of like a candelabrum, allowing the shorter branches to end up at the same height as the longer ones. You’ll need to use a scarring paste on the wound or even wax from a candle so that no dirt or insects can get in and put your plant’s life in danger.
If you take one of the branches on your plant and bend it slightly, it should form a sort of callus which will double the strength of the branch. The cells in your plant will make their way to the injury and they’ll strengthen the branch, allowing it to put up with much more weight. As well as not growing any more, the end bud will have heavier buds. All you have to do is bend the branch slightly, making sure not to go too far; if you actually break it then that’s that. If done correctly, you should end up with thick balls of buds and compact, strong plants. You’ll be able to grow less plants in your grow tent but with a higher production rate.
Pruning is essentially cutting a part of your plant so that it can direct its strength to other parts that can absorb light easily. This doesn’t mean that you can prune any part of your plants like the large leaves so that the light can reach the lower parts. Leaves have an extremely important part to play in your plants’ lives; they’re kind of like solar panels for plants, and the buds are the batteries. If light hits the batteries they won’t charge, it needs to hit the panels so that the light can be turned into energy for your plants. This means that if you remove the leaves you’ll end up removing a lot of the strength from your plants, as they act like nutrient deposits; if your plants leaves aren’t receiving enough light the plant will automatically absorb all of the nutrients, leaving the leaf yellow and dead.
The FIM prune is a type of cut that’s not followed through on, and it produces 4 or 5 new sprouds. At the beginning they may seem strange and deformed, but they’ll soon turn into sturdy branches, you just need to give them time. This kind of technique is perfect if you want to turn a cutting from another plant into a parent plant. Using the FIM method, you can get a lot of new branches on your plant, which will cause new slip sprouts to appear on the upper layers, which is what you’re after. The first time I tried this I got very good results even though I had never done it before, even though it might seem difficult, you just need to try and leave the middle tip when the cutting is still small, like in the picture, taking away about 60% of the tip and leaving the little leaves that were starting to come out. If you want, you can repeat the process when the tip begins to come out again. You’ll end up having an extremely dense parent plant, which’ll be extremely productive, meaning you can have a SCROG set up with a mesh in your grow room or grow tent.
Some strains absolutely hate it when you prune them to increase their number of branches, so in these strains what you’ll want to do is increase the amount of production on the central stem. These strains tend to be indicas. The one that’s easiest to recognize with this kind of shape is Critical+. These plants center most of their production on the main “eye” of the plant, the central calyx, so to get the most out of these plants you’ll need to place a whole lot together and prune/trim the lower branches. This way you’ll be able to grow up to 16 plants per square meter without them getting tangled. The idea is to prune those branches that come out over the flowerpot, leaving just the main stem and 4 to 6 branches around the bottom. To make sure that it doesn’t end up doubling over with the weight you should wire or string it, and you’ll have 16 extremely productive plants where before you could only fit 9.
To do this, you need to make sure that the part of the plant that you want to use as a cutting is above where you’re cutting, and that there are a few small branches on it. You also need to leave a knot above the spot where you cut so that when you plant it again you can plant it deep up to the knot, because that’s where the roots will be coming out of. You’ll need to cut it just like the picture, take off the little branch from the knot where we’ll be burying our plant, make sure that you cut it at a 45º angle, and then you should put it straight into some rock wool, jiffy, or whatever you prefer. After a few days, following the right steps (go check out the article we’ve done specifically on rooting clones), your plant should have some roots.
