by Keef Treez "The Defoliator"
Defoliation is an extreme marijuana growth technique. It's not to be done lightly.
In fact, the topic of defoliation is one of the most controversial subjects in the marijuana growing field. People on both sides defend their position vehemently.
I'm on the side that believe there is absolutely nothing stressful about defoliation or bending branches. Honestly, there is no way to achieve nearly a pound of buds from a 2-3 foot tall plant indoors, except using defoliation.
Opponents often have arguments like, "PLANTS NEED THOSE LEAVES! If they didn't, they wouldn't be there."
Or my all-time favorite, "I have a friend who used to grow, and he insists that will hurt the plant."
Yet the saddest part of all is how so few people are willing to look at the evidence.
In some ways, I almost would prefer the rest of the growing world keep up their ill-advised lollipopping, removing growing tips, and other low-yield techniques. The defoliation technique has been loudly condemned by "experienced" growers for decades. Nevertheless, I am determined to educate other growers about defoliating and let them see the results for themselves.
So let me start by giving you some picture proof that defoliation works (make sure you scroll down to see all of them!).
You see, I've been defoliating intensively for 30 years. I am now training plants to be 32" tall and 32" round and yielding 250-400 grams under 400 watt lamp.
Nebula Haze from GrowWeedEasy.com: Yes, that's right, he said 8-14 OUNCES of
buds of marijuana harvested off each short, easy-to-manage 32" tall plant, using
just a regular 400 watt HID grow light.
Here are two of my beauties (the one on the right needs a good plucking)
How-To Tutorial: The Controversial Technique of Defoliation
Despite all the evidence (I've posted hundreds of pictures and shown dozens of growers in person), there is still somehow so much skepticism about defoliation techniques. Growers, especially new growers, often just say variations of, "It's common sense, how could removing any part of the plant cause you to get higher yields?"
I recently attended an advanced seminar with a prominent fellow grower and got roundly booed when attempting to describe the defoliation technique, even with pictures showing dramatic benefits.
Unlike many other growers, I believe what's most important is studying how the plant actually grows, instead of assuming she grows how we think she should grow. Real experimentation and unbiased observers are the only way growers are going to learn how to get the best yields for the amount of time, money, and effort.
And it's true that some types of defoliation are brutal to the plants (such as when misguided growers removing all the leaves off extremely young marijuana plants), but other types of defoliation are actually hugely beneficial to increasing yields (I'll be showing you exactly what do do shortly).
And defoliation is beneficial for more than just marijuana, it also has been proven to increase yields for certain other types of crops. For example, it's well-known that cowpeas experience significant increases in yields when up to 50% of their leaves are defoliated during their flowering stage... (source)
This marijuana girl is 32" tall (the dimensions of this girl are 32"x32"x32" to be exact). She was intensely defoliated throughout her life.
And it's true that the real beauty of defoliation is difficult to translate in pictures and verbally.
But I will do my best to give you everything you need to start producing your own huge yields with marijuana defoliation.

Are you beginning to see the power of defoliation?
How Early Do You Start Defoliating?
I first started defoliating in desperation after many years of SOG, which I feel has proven to be too much work for inconsistent yields. After much experimentation, I've found my yields have been more consistent when training a single plant to use this space instead of 4 or 9 or 25 SOG clones.
Never mind the fact that in many states, patients are limited to just a handful of plants, removing SoG as a viable option.
Most growers who are curious about this do not want to perform defoliation on small plants. They consider the practice in veg to be too radical. And I 100% agree that totally stripping your seedlings of all leaves will be devastating to their growth.
And the honest truth is that defoliation isn't for everyone. Beginners are often already dealing with the drawbacks to their choice of method or media, and defoliation can be disastrous to any but the healthiest of plants.
Because of this, I sometimes hesitate to throw defoliation into the mix of challenges for beginning growers and I strongly advise any growers to experiment with defoliation (or with any extreme growth control method) in the vegetative stage only where there is nothing at stake.
That being said, I believe the only reason you should allow a marijuana plant to leaf out completely is in an outdoor situation where you want as large a plant as possible. In that case you can save deleafing for mid to late summer after full-stretch and branching.
The way I practice this method (growing indoors) leaves never get a chance to age. No leaves are allowed more than about two weeks existence. I start at the top in order to remove the shading. Removing lower leaf contributes nothing to the strategy of exposing usually shaded out mid and lower growth to premium light. I still remove older shabby leaves to keep it all tidy.
And this is where defoliation gets controversial. Many growers feel that controlling their plant in any way during the vegetative stage will significantly reduce yields. And I understand how it can seem that way, especially to new growers, before you've gone through the entire life cycle of the marijuana plant a few times.
Experiments show, again and again, that large plants with intensively prepared structure during extended Veg cycle yield far more than untrained, smaller, force-flowered inpiduals.
Nebula Haze from GrowWeedEasy.com: I've also found this to be the case.
Small marijuana plants that are forced to flower when extremely young are
can be fun as an experiment, but produce pitiful yields. Investing more time
in the vegetative stage to gain girth, while controlling the shape and growth
of the plant, has dramatically increased yields for me.
The truth is, that with marijuana, the real 'secret sauce' to getting enormous yields is when you've perfectly prepared your plants for the flowering stage. As any grower knows, once you're deep into flowering, there isn't a whole lot you can do about huge, out-of-control plants except hold on, pray for the best, and do better next time.
I DO NOT lollipop and advice strongly against it. I use defoliation to skillfully and artfully prepare plants during the vegetative stage, so that lollipopping becomes completely unnecessary. I am on a mission to refocus growing technique to never remove ANY productive growth. I believe only leaves should be removed.
Ultimately, the defoliation technique is a huge tool in the grower's toolbox that allows you to dominate the Vegetative stage. Then it can be used in the Flowering stage to maximize yields.
Defoliation is the Big Secret to High-Yield, Compact Marijuana Plants
My style involves intensive defoliation along with the twist and train method (a version of supercropping) using a basic net for support.
I only top once, if at all, at the 5th or 6th node(approximately) depending on the height and structure of a given clone. I also deleaf them at this time. The only plants that get more topping than that are because they had clones taken from them. I don't usually keep dedicated mothers, instead, I just clone the clones and cycle everything through.
Here is a close-up of a veg clone getting it's second stripping.

To get the best results, you should start defoliation in the vegetative stage. Leaf removal in bud is beneficial after stretch but most important to yields is management and the creation of a more compact plant with more budding sites in a given size.
Stripping and bending takes practice but you must do it to get practice. By starting in veg you risk no bud. Veg plants are replaceable so experiment and be ready to devote a little more time to prepare them.
I'd describe my stripping as "aggressive." Once your plant is trained to deal with defoliation, it's hard to go wrong. Plus, after years of experience, I've become very familiar with how these plants grow and always know what my outcome will be.
But defoliation doesn't end in the vegetative stage. I also continue to pull the fan leaves off of my flowering plants to expose the buds.
As far as when and how often, I don't get too scientific about it.
Usually if things look leafy, meaning that you see more leaf than budsites when viewing the crop, it may be time for another deleafing. It usually takes a week to 10 days for a plant to releaf to the point that there are 2-4 new leaves that have flattened and greened enough to deleaf again.
This repeated releafing process allows that lower growth to benefit from the maturing of the immediate leaf mass.
Leaf removal stimulates lower and mid bud growth by exposing those normally shaded out areas to premium light. Of course those new to the technique should start slow, but if you start too slow you won't remove enough leaf to see the best result.
You basically want to prevent any 'shade' from happening.
