Thanks for stopping by everyone. Some things have gone quite well, but I don't think I'll beat my harvest weight record because of the two shorties (WW and OG Kush).
What C99 did was totally unexpected: I've grown her twice previously, and she never did what she did on this grow, which was to stretch 400%. That was definitely unexpected, because she didn't grow all that strong during veg. I wonder if it's unstable genetics or what... Of course, I'm seriously considering growing her again next round just to see what she'll do!!!
The trick for me working in the grow boxes is to get the girls tall enough to stretch into the sweet spot during flower; I have a dial in the ballast that will allow me to turn down the LEDs (ideal for plants that get too tall), but not good for the shorter plants. I guess I could solve the problem by growing all the same strain in one box, but that is boring. I'm stubborn and I want 3-4 strains per box. So there's my trade-off when they all exhibit different growth traits.
Something else I have to learn to do better is to control the number of colas, get them into the sweet spot and then have 8-10 colas per plant that all get as phat is the phattest buds on this grow. I'm still learning how to use these grow boxes to their best advantage.
