I water 35 oz twice a day spread between 4 plants.
I'm 50/50 coco coir n soil, I do have some perlite in there too. 1 gal faberic pots.
I get some drainage out of the bottoms but not much. I use nutes once n just water once per day. I don't really have ability to up humidity without a humidifier and that would increase temps......
Lights off are more like 75-77. I do not get them much lower then that too often, sometimes lower if I blast my ac. On they are now 82-84. I had a bigger temp range opening up the closet door for a hr or two twice a day. But things are getting too big n starting to smell to keep doing that.
I re positioned my intake fan to work a bit better. Again, sometimes lower if I blast ac. But it's really only been a test to see if it would make a small/med/big difference.
Intake fan does not blow directly on the plants. I feel before I water, things get pretty dry if u do not water twice a day. I have lots air circulation very low in the room and then a fan directing it straight up to my exhaust
I do this for bugs, mold, etc. I have a couple $4 Walmart 3" fans I'll put by the pots right after watering so it dries somewhat quicker.
