I really like the cmh Phillips bulb but want to put it in a 2x4 tent and the footprint is only 3x3. Would I have issues flowering under a single 315w? I don't think I could keep temps in check with two 315 bulbs

I run one in a 4 x 4. I am suplementing with another light but the 315 is a rockstar.

300 to 400 grams 4 plants with a 4 to 6 week veg (topped and bent etc).
White widow, king tut and white rhino were big yielders.
