got some seeds from kc brains.i have a pc case 21 inches high.is it possible too grow tall plants in this case using lst?will it work?what kind or size pots should i use?how long should i veg them before flowering?
It can be done. You'd likely be best to do a stretchy sativa under 12/12 from start and begin training it as soon as there is enough stem to bend. I have a sativa in a 4" pot about 5 and a half weeks flowering. The first bend was at 2" and kept her tied down. The main stem is about 24" long now and only 6" above the pot in a spiral.
Yes i've done a sativa strain in a tiny box... im almost finished right now.. you just have to keep it root bound in a smaller pot and water it often! happy growing!
