Its the strain. I've grown Grapefruit Sour Diesel Kush a bunch of times with real bad light leaks and it got big fat buds, it didn't care (one reason why I thought the little light was OK). This is my first time doing this SSH indoors. ANY lights mess it up. Everything is recovering from the light leaks except the Super Skunks (they were close to the door where light was leaking in. I shut there lights off and chopped them down (18 6ft bushy plants, I hate big plants). I took 75 cuts of the grapefruit sour diesel and they already have roots hanging. transplanting them tomarrow. they'll be ready in two weeks to throw under those 6 lights. The grapefruit is insane, Its has a 22% thc and its heavy with a fruity smell. I don't know why I ever grow anything else. I seen your AK47?? pics. Your shit looks like some super fire!! You did a bunch of small plants? Was that ebb N Flow? with cubes. I use ebb in flow with 4" cubes, but I plug those into co co fiber during flower.
