You’ll want 4 of the QB288 boards in a light to cover a 4x4
https://horticulturelightinggroup.com/collections/quantum-boards/products/qb288-v2-rspec-quantum-board with a driver Mean Well HLG-480H-C2100
You’d get 14oz-30ozs in a 4x4 scroged with that. “1 plant to 4”
Light will pay for itself probably in the first grow
And like every said “go with the 6” or bigger"

I wouldn’t buy a light you plan on replacing. I would also agree that 4 plants in a 4x4 is quicker and probably more productive grow than 2 plants.

Wiring would be really EZ, It just depends how you make the frame" plate, aluminum corner," Theres a lot of ideas you can search (DIY) or ask member’s , they’ll be able to tell you anything you need"

I like the 2x288 light rather that a 4x288 for versatility.


That’s the first one, going to make 3 more already have the frames just waiting till I see a steal on the HLG-240h I need

Don’t those boards require heat sinks?
Or am I missing them as they are on other side out of view

There an aluminum 1/16 sheet in back and the flame being bulky dissipates any heat. Boards don’t even get warm. I was surprised.

As you can see we like to help.fox farms is a great soil but rather hot for seedlings. Most here start theirs out with fox farms happy frog. You will also need sm fans to move the air around.
Welcome to the forum. Great folks!!

Buying them with heatsinks helps with framing them

@ravenchief HLG lighting will be a solid decision, you won’t regret.
For a fan, I recommend the AC Infinity :infinity: in-line fan. I have the 6” in a 48x48 and it does great.
Plant count is a matter of opinion, however I recommend the 4 in there as that would make best use of the space, and you may not want too many just starting out. (Not that we would allow you to fail)

Any more questions just tag someone as you’ve already figured. Happy growing and welcome to the forum!

Thank you so much I am definitely going with the 6" and just made my first purchase of 4 QB288s with 2 drivers to make 2 sets of 2 - I originally was going to go for only one set of 2 but I got the fever and all the sage advice tells me to invest in the best lighting. I ordered the newer V2 r-spec with 3.5k spectrum.
I’ll be doing alot more research over the next few days - time is ticking…

I am implementing all your suggestions - thank you

You talked me into it - I was going to go quality but smaller, then I decided that this is the kind of investment that I know will pay dividends for a long long time. I am going with the same setup. Thank you…

I would suggest changing the spectrum to the 3k although the variable of that choice is the r-spec difference that would bring more red to the lights.

Any thought @dbrn32 as to which might be better seed to flower?
R-spec 3k or 3.5k

I don’t think hlg offers different cct with supplemental reds. You can choose cct with standard 288 boards, but r-spec is r-spec. You pretty much get what you get.

Just looked at them again and yep r-spec is what it is and it looks nice…lol
