I trust your experience and by extension your friends'.
My buddy who's cheap but big told me these are the best, and I was 100% skeptical. LEDs are *still* not mature. T5s hot and inefficient. Plasmas cost prohibitive. Gavitas/DE's run BOILING HOT and need very tall ceilings, etc etc.
Sooooo much stoner tech hype bullshit for decades, seen it all. Soooo much fail.
But 315s, after exhaustive research here, YouTube videos, tests and comparisons, data, charts, graphs... the PAR, color, efficiency, temps, yields, penetration, cross lighting, bulb longevity, just ALL THE DATA theres literally no comparison.
My
Solistek digi adjustables were unbeatable when I got them. Now Im planning them at 400w instead of the 1000/1100w they can push, and going with a dozen Boulders. The Boulders daisy chain! Up to 6! And they're adding LED pontoons for spectrum soon, plug right into units they attach to!
Adding 2 x 220v outlets gets me 12 (!) 315s, no need for control box just timer them (easy!), and dramatic increases in PAR, color, etc.
Will go to under 7000w down from 8800 (8 x 1100w overdrive HPS), lower heat, increase light and yields probably dramatically. Eliminate need for 2nd 3ton minisplit ($5k installed) and not need to spend a grand on bulbs every couple rounds. PLUS have open bulb 2k color HPS verticals paired with 315s for each tree.
And if Im correct, 315s have a share of UVB which helps kill bugs and mildew.
I see no problems except my time wasted and problems with 1000/1100w HPS in this build thats given me fits.
Sorry for long reply. I thoroughly trust
@We Solidarity and the exhaustive, highly skeptical research Ive done. 315s are mature, for auto showrooms, developed by Philips, and give us plasma results for a fraction.
AND they can go veg to bloom, no spectrum shock nor different lights needed. Am I missing something?
