Too keep a plant short, you want to keep it in shallow soil. At that point though, it would almost be a bonzai if not. I really wouldn't try to keep a plant that short if I expected much of a yeild at all (in other words, more than a quad to be honest). I would at least go for 2 feet even if I were doing my best to keep the plants small.
That's very interesting. I may have to try and apply this when I start my next grow. Although would it be practicle to do it during the veg stages at all or just do it in the flowering period? Either way I will definitely experiment with that.
If done right and if you needed to, you could have almost 20 bud sites with under 10 inches of height. I LST the crap outta my plants then put a scrog screen over them about 12-18 inches up from the buckets. I love LST!!!
