ive been running 600 hps for forever and last year i bought a 315cmh to see about the hype ..... what i found with the 315cmh was frostier buds but yield was off by about 10% and i think bud density was softer too .... my buds under the hps are usually like solid AF .. so my next experiment is run them together ...

The 315 is not a one to one replacement, 3 for 2 works fine. We did 7x 315 over 5 trays (that normally would take a 600 hps each) and yields were up on every grow. Not by much. Like every run was a perfect hps run.

The main difference was that we wouldnt see heat stress even if it topes out at 30C in the summer.
