Just my 2 cents:

During my first grow, the plants were transplanted twice: seedling flats to 1 gallon to 3 gallon containers.

This time, I sprouted in wet cloth baby diapers and put the best looking seedlings directly into 3 gallon containers. Since I used bag seeds of four distinctly different quality bud, I sprouted 10 seeds of each and selected 12 to plant; the three best from each type pot. (Like film at a concert, seeds are cheap and you just get one chance, so use more than you think you'll need).

Seems like everyone says that their plants thrived and "took off" when repotted. But mine would spend two days recovering, even though I've grown tomatoes for years and am pretty good about being careful with not damaging roots.

Also: I have a few tiny runts out of the main light and I pratically drowned them in bat guano tea at more than triple strength, just to see what damage to be looking for with my good girls...but they were unchanged and have grown a bit.

Just my 2 cents~
