If the 54A lights up the 2 boards, then you would need to change from parallel wiring, to series wiring to use the 1750 or the 2100 driver.

You've walked in and only one panel was lit. It would help to know if it the panel lights up at all during lights on then turns off at some point, or if it just doesn't light up at all.

Thanks

It looks like the auction is being carried out on IG too https://www.instagram.com/usefulseedco/ There is also an auction for 20 Blueberry and Chocolate fem seeds.

I'm pretty sure it's the timer. I had one which worked great for 1.5 years, then would turn on both sides at lights on, but only turn off 1 side at lights off. To test it, switch the plugs. By that, I mean, move the plug connected to the right side of the timer to the left side of the timer, and...

"Honey, you know those seeds I was looking at? Well, I was wondering if" "NOoooo!"

At 1050 ma the voltage on the V1 is 48.96 volts vs 46.98 for the V2. Got the numbers from here: https://ledgardener.com/hlg-qb288-v2/

I just hooked up 4 288s to a 240H-54B. Turned the pot all the way down. All 4 are lit and drawing 18.1 Watts or 4.5 Watts per board. Total light looks to be about the same as a 60 Watt incandescent bulb.

3Thirteen Seeds, which I think is Detroit's area code.

If you look at thr Flux Characteristics on HLG's site, you'll see the bottom row says at 49.86 volts, the board will draw 2.8 amps. If you multiply them you'll get 139.6 watts. Two boards at 49.86 volts, and the driver will output 5.6 amps for 279.2 watts. All those specs are within the...

Robincnn from HLG said in post #6047: As per datasheet hlg-320-48a is 43 ~ 52V adjustable. 288 may max out at 100 watts or less at 52V 2x 288 may max out the hlg-320-48a . hlg-320-54a will work for sure. I disagree with him about 2 boards maxing out 320 though, because the formula for watts is...

I would certainly give it a try. It will either work, although not a bright as it could, or it won't. Since the voltage is under the recommended amount, it won't wreck anything if it doesn't work.

Here is one of my hlg grows. Day 67 (from flip.)

Looks like that HLG light is trying to find a way into the tent. It wants to help! lol

It was ECSD bx1, which I believe was ECSD x (ECSD x Shoreline bx).

@800lbGuerrilla mentioned that he read somewhere that the higher THCV levels in high altitude plants might be caused by higher UV levels. As food for thought and off the top of my head, I mentioned some other parameters that change with altitude, gravity being one of them. No, I highly doubt...

I'm battling allergies, so I can't say exactly. I get an overall muted sweet smell. That was from Shoreline's ECSD (East Coast Sour Diesel).

Earths gravitational force is inversely proportional to the square of the distance between the center of the earth and the object. At 8000 ft above sea level, the gravitational force is roughly 9.796m/s².

Tell us which driver you're using and we will tell you whether to wire in parallel or series. If it's the HLG-240H-C1050A in the picture, then you need to wire in series.
