I ran mine in a tent that was 2.6×4.75ft. It was overkill as I ran the 630w DE bulb at 700w. Heat wasn't an issue at all. I run a single 6 inch hyper fan with a carbon filter for ventilation, and tent temps stayed 72-78° i haven't ran a single end 315 bulb so coverage on that isn't a question I can answer. What I can say is the penetration and par output on the 630w is equivalent to what I was getting with a 1000w DE hps dimmed to 750w.
The last grow with c99 I had to move the girls from the 2x4 tent to my 5x9 tent due to c99 deciding to overgrow my 2x4. So the 4 c99 finished bloom in a 5x5 area with the 630w at 700w. Bud density on the colas was phenomenal for a sativa dominant strain. Mid canopy was dense as well. Lower popcorn was fluffy, but that's normal. What wasn't normal was the amount of resin that was there. The colas were coated in resin, and so was the popcorn! The other big benefit of cmh is spectrum. All of the bulbs are high cri which is much easier to work under.
So the other thing worth noting is the test results. I had 2 c99 and tangerine kush lab tested. All plants tested over 18% thc. Tangerine kush was tested under 750w DE hps previously and came in at 17.77% thc with 1.20% terps. Under 700w DE cmh tangerine kush tested at 18.23% and 1.30% terps.
