CBD Blue Shark mainline

This was a big week. I topped the plants for the second time and clipped off all the branches below the mainline node. I thought about leaving these and going for more of a manifold technique since they were pretty robust by this point given the lack of apical dominance, but in the end, I wanted to see how properly mainlining would work. I think mainline / ScrOG will make the best use of my space, it's just too bad I wasted so much growth. It was a hard decision to make. I saved some of the cuttings to try to make clones to make myself feel better but it really felt like as soon as things were going well, I put myself back to square one. After about 3 days, they had recovered and I topped them a final time for 8 main colas per plant. I also bought a window fan to pump more cold air in, and while I was setting it up I realized that I had previously had my cool tube fan installed backwards. So both my fans were blowing in opposite directions. I disconnected the cool tube from the exhaust and now I'm running the intake fan pushing direct into the tent, the cool tube pushing from around the intake fan over the bulb to the exhaust hole. I took out all the extra ducting and it seems to be working well. My main problem now is that it's so cold at night with the intake fan running. I've been turning it off at night and back on in the morning manually. 12/12 next week will be a relief.
