Northern Lights Auto DWC

I think she's got 3-5 weeks left. I'm going to keep running my current nutrient mix for another 2 weeks or so, and then I'll switch from Big Bud to Overdrive. Anyone have any thoughts on that? This plant seems to be bulking up quick. The root system is MASSIVE, taking up most my bucket space. I may reduce the size of my net pots next grow to give me a little more depth available in these 5 gallon buckets. 6" net pots are nice, but they take up at least 1/3rd of the height of my bucket, so my roots get massive but then there's little room for actual water. I'm thinking they might get even bigger if I have more available space in my buckets. I'm also doing some changes to my grow tent. I moved the exhaust fan inside the tent to reduce noise, and I replaced 4 little (cheap) inline fans I had in all 4 corners (2 intake, 2 exhaust). In their place, I put 1 massive 200 CFM fan from iPower. Very nice fan! Powerful and quiet! I also used a bunch of duck tape and some heating ducts to connect a dehumidifier. It takes air out from the top of the tent, goes through the humidifier, and then blows back into the bottom of the tent. I wanted to focus on controlling my tent conditions instead of my whole basement. So far, this system is working great for humidity! It's also adding about 5 extra degrees of heat (in conjunction with the exhaust fan's heat, no doubt) -- which is welcome. My heat is now closer to 80 degrees F, which I think is ideal. The downside of this is that the extra heat buildup on the tent has increased my bucket reservoir temps. It got up to 71.6 today. Because my reservoirs are separate 5 gallon buckets, a liquid chiller wouldn't be simple or economical. I'm trying to think of ways to cool my air further instead. I might try some rubber tubes running somewhere cool. (Places engineering cap on.) For now, I'm glad it's under 72 degrees and I am also adding Hydroguard. Sensizyme should help, too.
