Hey guys just got my 630watt CMH light today. Switching from a 600watt LED my temps have went way up! So I am growing in a 4x4 tent I have a 6inch inline fan 440cfm with filter and a big square fan pumped lots of air in from outside of the tent.

I have all my fans on high and i am still getting 83 to 84F so just wondering how you guys are cooling your tents with mh/cmh/hps lights?

Thanks

Nice. I’m growing with LED for the first time. How’d you like LED and what made you make the switch?

Led was good but i did not find it was covering my 2 plants i got budding right now. I will be growing 4 plants soon and needed a better light that will cover my 4x4 tent. Not saying leds would not cover it. But i was running a mars hydro 600watt led and was not covering 2 bushy plants.

Lol that was probably like 200 watts at the wall that is why it wouldn't work in a 4x4
