This is my second grow (first one was soil) first dwc. My seeds came from my last grow that was seed less except for one bud. So i used them and they been veging for 5 to 6 weeks. I've never top them but out of 3 plants i got one that started with three tops and one the has two and one just got one. They started to pre flower and if my eyes are working right i have 3 girls.
My setup is diy 10gl tub, 4x 3.75 net pots jiffypulgs, lava rocks, walmart air pump, technaflora nutes, and a shit load of cfls.
My only question so far is what is the proper way to switch to flower.
