Grow Room temps issue

Cool tube... or switch to quantum boards. Suggesting adding a viparspectra shows why you prefer hps.
Quality cobs or quantum boards if you want something that compares to hps.
I run 450w of diy cobs in a 4x4. Passively cooled. I run 2 to 4* above room temp.
Thanks for the reply like I wrote Im total noob in Leds, Im just MH/HPS enthusiast ;) and considering them last resort atm :) If that will be the issue, Ill def do some research first so thanks for first shards of informations .. :)
 
Thanks everyone for the input and Im here with a little update ..

Ill see the readings after few more hours, but the easiest solutions are obviously always the best .. Fk me sideways but so far it looks like simple adding of 1m ducting in the end of extraction really solved it :D :D holy crap
after 3 hours I'm at 28 degrees .. fckn 6 degrees down!

I prefer hps as well, it's where I cut my teeth, and there's something about that warm orange glow that gets me. But the $$$... cant afford to run hps in California.
