One I have tried to get my way and just can't is a strain I got from a friend travelling to Canada. R2 as it is called; what I now can believe would look like a cross of northern light and super sensi star; the one I got is the short sister (r2 had two pheno; one huge tall one and one that stays short through its life) and is a surprising 60-40 indica that stays so short it's insane. Even in flo the build is already established and won't stretch more than 1 foot extra. Takes 10 days extra to start seeing bud sites but they do take off. Still though it will take 60-70 days from start of flo. Which is a bummer. This is all to say some genetics; no matter the ratio and the periods of drought given; will not bend to your will no matter what you try. I don't mind though; I'm on LEDs and would rather a short stout plant that produces what it needs to on the top.
