lighting?

So I am currently running 2x315w CMH, I really really like these lights, but I am in an 8x4 right now and picking up a 4x4 for veg. I need to put one other light in the 8x4 and will need to pick up another light for the veg tent. When I first decided on CMH I figured I would end up mixing in some LED's as I am concerned with high temps. So I was curious do LED's run much cooler than CMH's, cause I was surprised that they run as cool as they do? Also what brand of LED would you guys recommend? I am either going to stick one LED in the 8x4 and use one in the 4x4 or I could stick the 2 LED's in the 8x4 and one of the CMH's for veg. But I am excited to try out the 10k CMH bulbs towards the end of flower and if they seem to be all they are cracked up to be, I will probably leave the 2 CMH's in the 8x4.

Depends on your actual wattage used. A 315w actual draw LED will produce the same amount of heat as a 315 actual draw CMH. Now you may be able to get your plants closer to the LEDs than you could to the cmh bulb depending on the LED.

1 watt used = 3.41 BTU

Also on the LED it kind of depends on your price range and if you want to do any DIY?

I really like mixing CMH with LED. And for brand HLG is a good one.

that's one that is at the top of my list for sure! Have you tried the 10k bulbs at all yet? The companies producing them are not brands I would have picked to purchase the other bulbs... but thinking of giving the Growers's Choice 10k a try.
