315W CMH light in a 4x4 tent Rdwc only 2 plants? Should I add something LEDs? I know your can have to much lite as well as not enough light. Was going to do 4 plants with two 315W but temp was 95F. I grew 2 dwc with 1 CMH 315W in a 3x3 and it filled the tent pushing up against the sides and stuff.

You would certainly benefit from more light in that space but if you can’t add heat then u don’t really have an option, I’d be looking to add more cooling power and getting another light and led would give u the most bang for the heat

I ran a 315 in a 3x3 and don't think it cuts the mustard !

The question I'd ask is why did it get to 95f with 630w of cmh, is your system not set up right or do you live in a hot climate?

Tell us about you old set up , how was it ventilated, with what, to where????

Filling the tent and pushing up the sides is not an indication of the quality of your end product or if you had enough light in that situation

CMH are great!!!! Remember the most important difference is that you can swap out a bulb on a CMH to ensure its running at max, whereas when diodes begin to dim, you need to replace the entire LED fixture. CMH also offer UV light which the plants love.
