I almost have the same tents as you. Looks like u have everything figured out. When my temps get low I have a clip light w a 50 watt heat lamp from when I had bearded dragons. I clip it near a fan so it blows the heat down . And I go to 23 and one so the girls only have to stick it out for an hour in the cold .Alright, just thinking out loud here... I need to get this new tent running. Just ordered a new AC Infinity fan for it. I was trying to finagle a way to not need too but it's just not working out.
So the only question is what goes where... and here's my thoughts... would love some input, positive or otherwise
4x4x6 - obviously this is my primary flower tent. Thinking 2x 315 CMH here. Currently pretty happy with the CMH and LED combo I currently have going though
3x3x6 - thinking this will be my project tent. Full cycle phenohunting, testing and chucking. 2x SF2000 LEDs because they have the best spectrum mix for a full grow cycle
2x4x5 - veg tent. 280w DIY LED.... this is really my biggest debate, because it's hard to keep a good temp in here with the LED in the winter, its in a separate room from the other tents, so I'm considering going with a 315cmh in here and keeping the 280 in the 4x4, which is my current setup. The 280 is a better spectrum for veg though. Could also do a 315 in the 3x3 and both SF2000s in here since the new one is dimmable... or stick with a SF2000 and HLG65 in here and put the new SF2000 in the 32x32....too many options
32x32x64 - quarantine tent/overflow flower tent, 315CMH
Clone tent - retired for now. I'm using an open rack with my T5 for my cuttings and seedlings right now and prefer it.
