    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.

    How do you have the fixtures arranged for equale light distribution?

    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.

    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:

    Yep, top-dressing with roots organics and using ff grow big, tiger bloom and big bloom. I also mix my soil using peat moss/perlite/worm castings (roots org big worm) at about a ratio of 50/30/20

    he has 4k worth of hps vs 1260 watts of LEC and lec rocked it good. if he had double the 315 lights in there they would have beet the hps easy.

    My gram/watt math was wrong- I was at ~0.8 g/w, not 1.23.... lol

    Doc has been telling me to switch to LEC for a bit now. I finally listened and am happy I am. I am gonna have to bust my ass to get lights ordered faster. Its a win win to me.

    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
