DIY with Quantum Boards

Dialling in the panels to get happy praying plants in my current grow is doing my tits in.
Nothing wrong with the lights, just a learning curve.
On a brighter note, anyone putting these panels in a tent, as mentioned before they would not need lenses. Quick blast at near 600 watts will have dots embedded in your brain.

Off to have a chill it man smoke, while the bitches have their sleep.

Exactly right.

I ran at 60 watt per board for about a week and I'm seeing deficiencies. Nothing serious, but as they stretch I can see praying and canoeing starting up. I dialed down to 350ma per board, still a ton of light!

Seems like here is where a better quality of light comes into play. Plants are growing faster than I've seen thus far, and very hungry. A win-win.

So you're giving them so much light they used more nutrients than your setup previously pulled? Sounds like you were running sub-par lighting prior and your plants weren't reaching their full potential. Pretty cool!

Yep my noob slip is showing lol.

No experience with HID, but I went from CFL to T5 to Mars Hydro and now to finally to some real lighting. I'm glad I kept good notes because this is the third run with this strain and its clear they want more nutes than previous grows. After a heavier feeding at this point, I see no signs of nute burn.

Keeping a close eye on things and double checking, hard to imagine less than 100 watts in my grow could produce more bud than the 500+ watts I was running a few months ago.

This is exactly what I was trying to express early on when I was testing if anyone remembers. The growth rate under these boards is staggering compared to the watts used by other lighting. Its a combination of being a COB light but better light spread foot print. Its not one point of light but 300+ per board. I have fan leaves on the bottom pointing at the walls of my tent lol. Cool stuff !

With no air movement (which should never be the case in a grow room) these run 55-60C @ the above suggested drive current which is well below the 100C maximum and most luminares that use mid-power run at around 85C. The Philips Lumileds 3030 2D we use in the razor 250 is color binned at 85C! Heat is the drivers biggest enemy. Also most Mars panels aren't even 1/2 as efficient as these. Lots of heat for the light provided. No paste is necessary as the copper layer distributes the heat evenly across the board. As can be seen in the thermal images the heat really is super even. @robincnn has tested these with thermocouples and the camera is spot on. I think you would exceed the maximum allowable current on the diodes before you would need a thermal interface material.

2 HLG 240H 2100/1050 A version will pull 600 watts turned to full bore. I like to run these at around 550 watts to give the driver a little head room. The output is something to be seen for sure. Like I said the guy that runs Nanolux and is a grower in CO bought the razor 250s and loved them. I sent him 4 QBs on a 320 H with no heatsinks on a flat aluminum plate he wanted more. I told him I could increase the power with the addition of the heatsinks. He got 4 of those and called me and ordered 6 more. He's eventually going to switch out all 60 DEs. Woot


Hell the Tj is only 2-3C higher than the case temp!

The face of the led only runs 1-2C higher than the board. Copper moves heat 2X better than pure aluminum. Now if you consider most heatsinks are alloys that move heat even less efficiently than pure aluminum you can begin to see how these do so well.
I wouldn't even mention mars and QB in the same sentence IMO! Mars is Chinese Junk!

Ok. I am seriously considering doing a side by side with
1. Hydrofarm SE 1000 watt. May add a better bulb. Local store has Hortilux bulbs on sale.
2. Nanolux DE up to 1150 watts. My crony bought 2 and I have not used them yet. I would not buy one.
3. QB rig but what? Stephen and Robin had a 4 board rig with a reflector. What about 6 board or 4 board with 2 COBs? I want to try to make it a fair comparison.

Finished a grow with Hydrofarm SEs which are old school bit they did well with so so bulbs. Good strain, good coco set up, co2

4 boards on 2 HLG 240s will give an SE Hps a fair battle. Total wattage draw of about 600 with this combo.

6 boards on 3 x hlg 240-1050ma wired in series will be a fair comp with the de.i would guess it would destroy a single ended lamp setup.about 700w of quantum fire :)
Edit 8 boards and 4 x drivers for a solar fucking storm of photons lol

I would like to scrog around the perimeter of my room using the center as my working area. About 2-2.5' from the wall. The room is almost 10'x7'. I think thats around 40 sq ft to cover.

Would i be better off using cobs ? These quantum boards seem legit! I am shooting for efficiency and heat is a concern. I have heat issues sometimes running the 2600 watts of hps that's currently in there
