I decided due to my height restrictions, LST was pretty much required. #4 was 18" and #2 was 16" I had already done this to a topped male and #3, the female that took 2 weeks to show 1 calyx and pistils. It was a difficult decision for #4 as she was so pretty, but she was growing near an inch a day since repotted, and only really had another 6-8" before I had to bend over tops. #3 was bent over at about 8" and has turned her top back up. The lower branches are responding to the added light. I probably should have started the LST earlier, but oh well. #4 and #2 were bent over at 12".
I had planned to start flowering at 18", and since #4 was...I cleaned out the flower box, moved all wiring external (besides 1 light extension cord for ionizer) and touch-up painted. I moved the 2 girls in 3 gallon pots (#4 and #3) under the HPS. The LST was an afterthought once they were in the flower box. The tops had lots of new growth and were bending from their own weight with the help of a fan. It was almost like they wanted to bend. As I played with them, there was no going back. I bought myself a couple of more weeks of veg, maybe. I also wanted them to get used to the new environment (9,166 lumens/sq.ft.) as well as open up some space for the K-train in the veg box. They are currently 18" from light and seem to be fine.
Due to only 3 females, 2 k-train will be flowered 2-3 weeks behind the 3 red diesels, and hopefully a headband zombie 2-3 weeks after that. The strongest k-train will be have as many clones taken as possible, then put back to recover and kept as a mommy. Probably start 2 AK-48 and 2 power skunk in 2 weeks. I am still a little freaked out about femminized seeds (what causes them-no straight answer, and I don't need bigger moobies!) but I sure understand the value of them now. I was hoping to do better than 50/50, but if that cant happen then males are a huge waste of space, time, soil, and hope.
