I vegged them under 4-4' Cool White flouros in premium shop lights from Lowes because the reflector was bigger. 6 were from unknown clones and 2 were from wicked bag seed. Lost track of how long I vegged them but was less that 5 weeks. Then I put them under the "Big Gun" A HydroFarm Radiant 1000w Hortilux. The best thing I ever bought. The first time I turned it on it seemed so bright I said "Oh my God, What have I done!!!" I love it. I'ts a challenge keeping the room under 80. It runs about 76-82 degrees. I'll probably have to do some vent work for the next crop. Tomorrow will be 6 weeks. "Let the Games begin"
