I have a hard time keeping heat up on my tent. I’ve resorted to pumping air in thru top and venting out bottom helps during lights on for sure. I also cut down how much air whips through the tent.
Im wondering if color temperatures can effect how much heat is output, like if a warm 3000k led puts out more heat or transfers more heat than a 4000k.
As for leds 3000k/4000k shouldnt have any difference in radiant heat output.
With hid its a bit tricker: 1000w of hps or mh should be the same heat, but the mh coil/filament inside the bulb burn hotter: the 2200K /5000k spectrum rating is related to the light emissions of a blackbody object at a certain temprature.
One thing to note though re led color temps:
One of the reasons you need to control your lower temp limits with leds is due to transpiration: you need to work your environment and temps to get your plant to "sweat" which is the motor of your roots drinking. However many people forget that this is not the only factor in transpiration; spectrum, specifically blue and uv, have a very strong effect on the stomata opening. So even though the 4000k will give the same heat as 3000k the 4000k will have a leg up in the cold since it has almost double the amount of blue. But as you approach maximum light intensity this advantage will get less and less as the temps are also needed for the metabolism to keep up with the photosynthetic rate.
