Better quality is almost garunteed, but maybe not as much weight...

The quality will definitely improve. As for yield, you should be able to get around 80% of what you were getting under the 600w HPS, using only half as much electricity.

If you can' pull the same weight using a 315 vs a 600, try a few differet grow teks. It' very easy to do.

If you can pull the same weight with a 315 LEC as a 600 hps you are doing something wrong under the hps.
Sorry but it’s true. And I’m sick of the exaggeration. I wish I had not bought into the hype. I have tested it many ways now.
The 315 is going to the veg tent where it belongs. I would need to shorten my plants bud canopy and add more lamps to replace my hps effectively to not hurt my production.
3-4 over a 4x8 might work with the overlap. Expensive test though.
Even at 1 gram per watt hps vs 1.4 for cmh the math is obvious.
And plenty of Growers have gotten more than 1 gpw from hps. Me included.
The only real benefit is the uvb. But that is blocked by thick reflector glass. And I would prefer the natural light to see the plants better.
The bulb equals a 400 w hps for comparison purposes. Maybe 450.

Why are you using glass with the CMH?

I would never do that. It is recommended above in this thread with the conversion kit that also ruins the connection of the new base with a mogul adapter.
Sorry for the rant. Anytime I have listened to the hype here and made a purchase it was bullshit. Someone else who already invested was just exaggerating.

No, I' just a damn good grower who has his rooms dialed in.
Just because you can' get weight with cmh, don' knock the ones who can.
Bunch if whiney asses who can' grow.
Your a fn idiot. Keep listening to what the mfg says and keep getting shitnregurns.

Who recommended it? I set one up like that initially, then took the glass out, then bought vert hoods after metering the coverage I was getting with that. I'm just fucking around, not recommending anything, totally new to CMH. Now your saying CMH only belongs in Veg? Seriously?

What are you talking about? I’m matching or exceeding your cmh yield with individual spaced out seed plants. And far exceeding your yield with 600 hps.
If I get known clones with a net like you I would do far better.
Just do the math. It’s simple arithmetic. You ignore what I say and just keep talking. But your not proving anything about the lights.
They are just tools. And in the case of the little 315 underpowered ones.

Demon keeps recommending it. He says his old glass enclosed hoods work better than the ones designed for the bulb. I use the sun system remote vertical open reflector.
And yes I am saying we need more bulbs to cover the same area or use the 315 as supplemental light to an hps for best results flowering. Best plants I have grown were with 2 600’s and 1 315. Same ratio recommended for Metal Halide by many experienced Growers.
I am sure it is great for veg. I am installing soon to see. I have already done a year of side by sides with my set up.
I almost bought another. Growers House is doing 15% off again. I want to see how 2 do in a 3x6 area to see if it is worth the expense to use more for my new flower room. But I am pretty set on 2 600’s with 1 315 in the middle over a 4x8.

I'm swapping my 400w of Chinese COBs for one 315 in veg. Grabbed one of those $110 SS RA's. I am set on trying using purely LEC. I'm def not a pro or anything...if I could match what I did with a 750 HPS and see an improvement in quality with 630w of CMH, and enjoy less heat...I'll be happy.

You said that you tested it "many ways", but you've only ever shown us your 315 in the middle of a mostly HPS garden, which is not an accurate way to test the light on its own merits. To my knowledge, you've never done/shown a stand alone CMH only grow under your 315. Sir, the scientific method behind your rationale is haphazard, at best. You've also personally stated that the plant under your CMH exhibited more color, more pronounced terps, and finished sooner. You clearly didn't adjust your growing style to get the most out of the light, which is something that needs to be done in every garden, it's called getting everything "dialed in". So just because you weren't able to get the most out of your 315 CMH doesn't mean that others aren't capable of doing more with the same lamp.

I had the 315 separate from the hps all last year. It was outside the footprint of the blockbuster in the other corner of the room. I put it near the center recently.
Do you get more than a pound under 1 315? I said I didn’t try monocropping known clones. I got 15 oz from 3 different plants.
I ran 3 sets of clones a bunch of different ways but I didn’t push for yield because I normally grow plants in all different stages and measure monthly output for quantity.
Growing in potting soil and with different seeds every plant. And no co2.
And my plants are trained to max 30” tall. And I keep space between them and have plenty of airflow and stable temps within 3 degrees and stable humidity within 10%. And I adjust them all for happy leaves individually every day.
Anything else I am doing wrong? I average 2 oz per gallon of soil with the occasional 3. The footprint and lower bud development is lacking on the 315 compared to a 600 hps. The extra plant under the footprint is worth 5.5 oz to me. And less loose lowers which I count on because of my low ceiling height and small space.
I got it to perform as well as a 450 hps if such a thing existed. Which is what most say it will do.

All you punks arguing about gpw, etc.... that's not why you go with cmh. It's for quality, low heat inefficiencies, and general plant health/happyness, right?
Regardless, I'm excited to see what i get on this current run... day 16, a single 315 lec with 6 ladies in one bathtub (a dream of most men
)

Looking good.
