Which would produce more DO in a DWC?

Hey everyone, checking back in. I took a break from growing to work on a few other projects. I built a pretty massive (and costly) led light(s), but never got a chance to finish a grow under them.

My new setup is pretty damn cool! The lights have a 5x5 footprint, which I wanted to make up for not having reflective tent walls. The frames I built are super light, especially since the drivers are mounted on the wall, where a fan blows on them to keep 'em cool. I blacked out my lids, because I'm not concerned about heat. I have to run a small heater in there to warm up the room.

All these lights are overkill for these little ones, even when dimmed. After these pics, I raised one light and moved the other light to the center set of ceiling hooks. The three pairs of hooks makes it so versatile.

I LOVE how I can hang these to the side when I want to get in there and work!

The single light is much more efficient than running both. I've got it dimmed to around 25k lumins. When I crank it up, I get around 45k @ 18" to 24".

Other light hung out of the way. I'm also still feeding air to my controller, which keeps the water at 69°. No chiller needed :)

Don't really need my exhaust fan just yet. The only reason I'll run it is to filter the air during flowering, which I'll probably vent the exhaust in the room rather than the attic.

a blast from the past!!

love the new light.
can you post component list? i'm mostly curious about everything other than the QBs.
@andymex was a tremendous help with this, and put this parts list together for a $1,000 budget. I think in the end I was probably around $1,200, with all the hardware.

16 qb 132 3000k
2 hlg 480h c1750a
20 of these diodes https://www.rapidled.com/solderless-semileds-ultra-violet-uva-led-390-400nm/
2 of these drivers https://www.rapidled.com/mean-well-lpc-35-700-constant-current-driver/

Here are some pics of the frame I built. Its very strong and very light. I can carry each with one hand. On top of that, it takes less material to build, so its cheaper. Its just a 4' square bar, and angle iron (both at Lowe's, HD, or most hardware stores.) And yeah, I know its not angle "iron", but thats what we've always called it LOL!

Feel free to copy my design and post pics, and ask questions, of course :)

How ya been. Anything interesting happen in 2020 lol! Thank God for weed, eh!
good man, thanks. not much happening here: becoming more of a hermit!! lol.

so those blue/uva leds are just hard wired together along the center mast of the frame?? why did you go with blue? i have a similar array of 4000k qbs but i went with 2 of the growmaus far red pucks in the middle. but blue and or uvb in the middle is what i'm thinking about doing next. the far red was my attempt at the Emerson effect along with the QBs

Yep, just wired and straped to the center mast.

I just went with what @andymex had suggested to start with, but knew that I could expand a little later. I just had to get these done and hung. They took a little while to build, but that was probably due to having to figure things out along the way.

Ya def need to add 660 and 720nm red and ir is a must have ... uv can cause serious problems if they are ran too long...i run uva and uvb both which is a must have for uvs and uvr8 but just a hair of uvb is the trick.....

Very cool setup!

Did you wire your drivers in series or parallel?

Here is one built using a combination to cover all spectrums.

There are Samsung strips, and bud booster strips mounted in the frame with 9 QB's.

6 QB's @ 4000k
3 QB's @ 3000k
4 Samsung 96 LM301 Strips @ 2700k
4 Bud Booster Strips that cover IR, 660 and deep reds

600Watt Inventronics Running the 9 QB's
200Watt Meanwell running the 4 Samsung strips
200Watt Meanwell running the 4 Bud Booster Strips

With Dimming on each driver gives the ability to "tune" the spectrums as needed...heatsink only needed on the Strips.

Forgot to turn on the strips in the pic! Doh!

I've got an Active Aqua 60W, 70 L/min pump coming for my 4x5 gallon bucket UnderCurrent build. An 8 output manifold comes with it.

What I'm wondering is, would 2 air stones per bucket produce more dissolved oxygen than 1 air stone per bucket at twice the pressure (because 4 of the outputs would be shut off)?
It would be good to have 2 as a backup safety, incase one goes down while your away.

At some point I'll be expanding on my light rigs with some of the components you listed. It cost a lot to build, so my wallet needed a rest LOL! But after it recovers, I'll beat up on it a little more :)

Along with dimming, I am tilting the lights to account for a slow grower...

How are you adding ir?
