I can confirm this,so far only place I've used them is veg and it definitely cut down on time vs t5s.
I have 4 new ones sitting in boxes that I'm going to mix into my gavita flower room but it's summer break/vacation time first.

I'm here to always help ppl when I can.

If I need clones to grow faster, I move them to my veg room under cmh. It's stupid crazy how much faster they grow.

79* lung room air, 3x315 in a.c. hoods, 82* canopy height, no a.c..

The 315's are awesome for trich production but running them solo I think you won't hit the weight you want..

I have another grow going next to these in another room and these are kicking the shit out of a 1000W HPS in everything including mass on the buds.I dont see the 1000W really giving me more weight.Now a true side by side comparison with same strain or clones will be the way to go.I will be doing one of those after these are all done.I have 20 Greenpoint Tomahawks im gonna sprout and put half the females under the 1000 and the other half under the CMH's both areas will be under DWC recirculating so well see.
Tomahawk is GG4 and Stardawg X.cant wait to see some of them growing under CMH.will deffinitly be an epic grow journal.

That would be good. I'm not very experienced but my grow partner is..
We run flood and drain tables with 2 x 600hps and a Phillips CMH above each one..
He's pretty positive you don't get the weight with the CMH's by themselves so I would be interested to know your results seen as heat is an issue for us.
If you think there's no loss with CMH I will overrule him and put three above one table and see what happens..:ninja:

i guarantee 2 315's will kill a single 600HPS in weight and quality.I would not even second guess.I have a 600W and just ran 2 plants under DWC and my 2 315's are going to yield almost double what the 600 did no doubt about it.If you replaced a 1000W with 3 315's they would flat out murder the HPS there is no doubt in my mind.Like i said i have 630 watts of CMH doing the same if not better than the 1000W HPS.

That would be nice.
The tables I run have an open hood 600hps at each end and a Phillips/Dimlux 315 in the middle.
We just chopped down yesterday and the ladies that are in the middle of the table you can actually see are more frosty than the others..
We are going to keep replacing the 600's with 315's until we have 4 above each table..
