I’m digging the 315w cmh I’m using as supplemental light for my gavita 1000w.I would run multiple 315’s spaced out about 2.5-3’ personally. I am considering 3 in a 4x8.
But my open verticle reflector with the phillips bulb was easily as hot if not hotter to cool than my glass enclosed air cooled 600’s.
So open 630’s are out in my low ceiling small rooms amd tents. In the summer anyway but dont change my stuff often as i share house hbac with my grows and run a perpetual with no down time.
