Sativas can be killer smoke, but this is the exact reason why I can't grow'em: Space issues..
If I let a full sativa get 17" before flippin', it just won't make it..
And 14wks or longer is waaaaay to long for my liking.. I use 3gal. bags with a 2-4wk veg on indica doms and they still get around 3.5ft. tall.
4.5ft is my max..
And I heard pw is some serious "kill bill", but I just can't grow shit like that unless it's only 2 plants and I tie the hell outta'em, ya dig...
