Club 315w lec

Side by side with clones.... 315 holds its own with a 600(but it's only 315 watts)... fact.
Seed plants are seed plants..no way to really tell anything.

630lec next to a 600 is doing just fine also...better imho.

I posted some of this and have told you before. I ran 3 cuttings each from 3 known mother’s 3 times in each configuration.

Then pulled the 315 out for the summer to be sure of any results I got earlier.

The hps grew more potent and less leafy buds.

It is Hortilux super hps so there is some added needed blue light in their spectrum.

The 315 as supplemental helps with compactness some strains shorter ripening times and much more colorful leaves likely due to the fuller spectrum.

The 600w Hortilux blue out grows the cmh 315 too. But even looser leafier buds.

I think that it is easier to achieve potential with the cmh than the harder to dial in hps. The plants like less intensity during ripening in my opinion so I back the mature buds away to retain terpenes and help the buds keep growing with less light stress.

I read this and get excited to use 315w CMH/400w HPS housed in 1 glassless hood. Not sure it's all hype. Are you saying if you put a 315w CMH in the same space as a 600w HPS you get 30% less yield. But you used 48.5% less power. What if you put 2 - 315 CMH at 630w, in a 3x6 space, or individual 3'x3', would the yield per Watt be only 5% more than a 600w HPS in it's ideal space.

Well I said those were my average results with my known plants. The weight was lost mostly in footprint. But also in leafy mid buds and lowers.

And that is with 30” tall from the pot bushes for reference.

And of course that is my plants that I was running and that room. And me. There are tons of variables. I had a learning curve with the new 315 at first too. And I had been using the hps a few years perpetually already.

I do think it will work great alone in a 3x3 tent with a nice 6” exhaust.

Okay I got a couple and see how they are doing. I am gonna replace 4k of 1000 watt lights with 12 315 watt lec so 3800 watts and I bet I do 20-30 percent more yield with better quality. I am gonna fast forward to the end and go back 10 pages tomorrow.
How big is your room?

I am buying 2-3 lights each month till I have them all but will hang them as they come in and replace another lights with. got me a new cmh 400 bulb today 2100k I will mix match spectrum in the room 5 3100k/ 6 4200k and the 2100 cmh 400.

Here's my blue dream and choc mint og, run #2, soil, ff and roots organics with orca microbes, under a single 315w lec. I only ran one of each last time, and going with 4 this round, 5 next round. The blue dream literally smells and tastes like candy/blue berries.. i have yet to see anything that even comes close in quality from dispensaries... YUM! some SERIOUS fire!!

Also, for those wondering about yields using cmh, my last run (first in ~2yrs) i got just under 8oz, so that's 1.23 grams/watt if you use the 315w number, and that's the weight a bit over-dry (after curing) at ~45%rh. Not sure what the actual wattage pull from the wall is... Regardless, feeling pretty proud, being a complete novice and all.... :weed:

So you're blending FFOF & Roots Organics?

Also, for those wondering about yields using cmh, my last run (first in ~2yrs) i got just under 8oz, so that's ~0.8 grams/watt if you use the 315w number, and that's the weight a bit over-dry (after curing) at ~45%rh. Not sure what the actual wattage pull from the wall is, so this is conservative estimate on g/w... Regardless, feeling pretty proud, being a complete novice and all.... :weed:

Your math is out to lunch....

8 oz- 224 / 315cmh = 0.71111111
my first run with the bulb was 302g/315cmh=0.9487

And yet there are others getting 448g a bulb for 1.422222
