I do some training, i generally will top if it's a strain I have worked with before. I also do a little supercropping if I've got some extra time to veg...
as far as self watering pots go, i tried using wicks once. it wasn't for me. I have seen the self watering tomato things at lowes, but I haven't read about making my own. I am guessing you use them? what's involved?
