I got 2, was going to try LED, but 3 CMH 315Wers in 4' x 8' I think may be perfect.
New globes out as well apparently giving even more spectrum range, especially around the red and blue .

Mate that is bloody beautiful!
Its all in changing your growing style with these things, and not much, mostly canopy level.
Top Job please let me know the dry weight per light after harvest.
Will check your journal out mate, I always miss some...

Took a while but the final tally is in.
Under six 315 CMH A slow start with poor clones I might add
3.76lbs. dry weight so a little over 300 grams per light.
All in all a win for a new set up, next round 50% more no prob.

Thats awesome Joe! Roughly 1g-watt after a crappy start. Well done!
Lovely pic too champ.

Yeah, I think dialed you could push 2g-watt in coco. Dont be scared to get the light right into them too, they love it.
I should go an easy 1.5g-watt dry..... Even that is 2 pound.
I think a pound a 315w light is quite achievable....4 plants...4oz each...easy.
About 1.5g-watt.

I agree and what we are pushing for and more. The lights being new to us it will take a few grows to really dial it in as to height and wattage settings during different stages of the grow. Impressed so far and we are off to the races again.
