running 2x 240 watt qbs at 21inches from top. I just checked again and its around -6 for the very tops of the plantsYup, if the ir gun is correct. That's why higher temps while using LED is bueno. Mine is usually -2 or -3 difference. How far are your lights away? And what light? Watts?
Should I still drop the temp at night or is it ok if they are fairly consistent?1.2 and up from here on out imo . The heater should def help lower rh
Thank you, this chart is awesome.Most defol before flip and at 21 day mark. I wouldn't worry about herms w/ defol. That's more environmental imo.
with your temps on the low side, that rh is acting higher than its reading. Look into VPD. Vapor pressure deficit , here's one I use.
- if you raise temps to 79-81 (if using led, 81 is good) the RH will drop on its own. If you lower temps more the rh will rise faster and easier. I'd look into controlling the temp/rh for the room , then you'll see a difference inside the tent. But yeah defoling now will help, and help your buds![]()
