Good advice. I don't usually zip up the tent all the way and have a huge fan pulling air out of the tent. I can easily slow it a bit. I'll start monitoring the temps in the house. Doesn't get colder than 68 in the basement though.

I’m looking to jump into boards. Really need advice A to Z. Especially with the alibaba ordering process and best sellers. I hav access to drivers and heatsinks. Just need boards looking to cover 4x4 flower. Help please.

my goto advice on 4x4 (if you have access from all sides of the tent or have a way to raise/lower a 3x3 feet fixture) is running
3 x FoTop lm561C, 3000k 80cri, (about 80$ each+shipping and customs) on a
meanwell HLG480h-48A. dont buy it in china, get it from somewhere you can easily claim warranty, no international shipping.

you wont need a kit or heatsinks, these boards run fine up to 200w each. 2400 diodes!

Asking about the light itself more than the price but thanks for lookin out. I'd be paying 220$ each not whatever it's currently listed at
Existing 288 users could pitch in about the lights. I'm looking too. If you haven't already, check options on Alibaba as well.

What I did notice though is, on eBay the seller mentions SK bin but when I asked him on AE, he said his stock is SJ bin.
