Sounds like the FGI Light Square. https://www.amazon.com/FGI-Spectrum-Variable-Inspired-Growers/dp/B07R75T7CP

Anyone using the QB11 in 660nm? What driver, how hard are you pushing it, do you heatsink it, how much space are you covering per, etc.? Curious how peeps have been implementing these boards, as there appear to be a lot of options (based on the specs on HLG's site).

I've been vegging under straight 3000k for a couple of years, and I find it works wonderfully well. The only space in which I use a different color temp is the nursery for seedlings and clones, where I have the babies under a 6500k CFL. (I do have one 3500k space, but it's rarely used - and I...

Just as he's getting a new room together, he disappears off the face of the internet? That would suck.

Going in a new space, or adding/replacing in an existing one?

Toxicity of the work environment? Bummer. Mau5 seemed really excited about joining ChilLED, and then it fizzles right quick. Oh well, hopefully it's not the last we've seen of Growmau5, because he really is one of the more entertaining and informative dudes on the scene. Just don't understand...

It's been a while since I posted any pics, so here are some shots of the latest QB-grown harvest (chopped last night). Strain is HSO Blue Dream. Straight 3000k, four QB120 V1, run at 250w. The plant was half-dead when I flipped to 12/12 (at my wife's request - I would have waited to...

Slowly, carefully, and sober-mindedly - even if you aren't quite sober.

Doesn't look like light burn to me. What are your room temps?

It's widely accepted that this is due to lower leaf temps. HPS growers are accustomed to keeping their temps in the mid-70's (F), but under LED you really need to be running your room over 80°. HPS puts out a lot of infrared light, which heats the leaves up; you need the higher leaf temps to aid...

Yeah, I've thought about it, but I think I'll wait until there's a good, affordable DIY LED option, because the way my lights are set up, I can't easily integrate floros. And everyone has been more than happy with the weed coming out from under straight 3000k, so I don't feel too rushed to try...

I'm contemplating getting two more of the V1 boards, actually... If I get to them before they sell out, that is. Planning a new, smaller tent, and although I'd really like to try the added 660nm in the new boards, the price of the old ones is just too good to resist. Besides, I've been very...

What make/model and what are the specs?

Budget?

As I recall, @PSUAGRO. has run the straight 1750k before.

I think it's definitely worth the initial additional investment for two 120 watters. @hybridway2 the layout of the 245w model certainly looks good for a 2x4, but it's a bit narrow to make the best use of a 3x3, I would think.

Perhaps I've mistaken you, but I understood you to say that leaves don't need light, buds do. Last I knew, very little photosynthesis occurs in the actual buds, with the leaves doing most of the heavy lifting to supply the plant. If there's been a change in our understanding/knowledge of the...

I've never seen anyone strip a plant completely bare, but certainly people sometimes strip them down to almost nothing. I'm not convinced that proves that the leaves don't need and use direct light though.

Reference, perchance?

I was a ROLS grower for quite a while and just recently tried hempy, and I'm digging it. Definitely seems like I'm seeing faster growth. Haven't tried nutes in soil though.
