    Is this fan okay for a 4x4?

    Hey. I currently have a 200cfm fan that I used to use for my 2x2 running in my 4x4. So far no issues that I can see. Every so often it gets into the high 80s, like 89 degrees f but that's not too bad. My only concern is that I may not be drawing in enough fresh air for the plants to do as well...

    Help with drivers + recommendations

    Hey guys, I'm trying to build a small light to drop in the middle of my 4x4. I already have 4x288.2 QBS but I'd love a cri 90 for the additional reds and to help get light down low. I have two drivers from a mars hydro, both are .63-.65 Amps and 95-100V. The light i'm trying to buy is...

    In need of a par multiplier for QB setup

    I could change it out for something different. Maybe i'll try to sell it off and install some strips instead. I'd just also have to buy a new driver. Probably worth the investment though.

    In need of a par multiplier for QB setup

    Hey, everyone. So I bought a lux meter. I understand these were no good for LED back in the blurple days, but now I'm working with 4x Atreum 288.2s using LM301Bs and the Spectrum King 140W to power a 4x4 space. I'm trying to figure out par using my lux meter but I can't seem to calculate...

    My Atreum 288.2 build (HLG 550 on crack)

    I thought they were pretty secure but it doesnt hurt to throw two more rails.

    My Atreum 288.2 build (HLG 550 on crack)

    Hi guys! I just finished my first diy build. Using 4x 288.s along with my Spectrum King 140W. Powered using an HLG 480 B. What do you think? I even took apart an old 100w light and used one of the drivers to power a few strips for my seedlings. Works great so far. Next i'll be converting a...

    Question about strip builds

    Some EB Series Bridgeflex strips. They're 1 footers and currently only a little over $4 a piece. I have a mars hydro and I took out the two drivers, they are both 55-86 v at .63-.65 amps. I plan on using these.

    Question about strip builds

    Hey, guys. Pretty simple question today: Do I need to have something underneath the strips or am I okay to mount just the ends to a frame? Would they potentially get too hot this way or would this help keep them cool (esp with a fan going)? Thanks

    Driver/ Led Build wont power on! Help!

    I definitely owe you one. Thanks so much. My girls were loving it last night for their first time. Went from one 140W Spectrum King (currently in week 3 of flower) to that plus 480W of quantum board LEDS. It's an ungodly amount of light.

    DIY with Quantum Boards

    Hey guys! I'm new to LED and wanted to ensure I'm going in the right direction. I've watched growmau5s videos, read a few guides on ledgardener, and now i'm ready. I bought 4 Aetrum 288.2s with the heatsink combo that I plan to flower with alongside a reptile uvb bulb. My tent is a 4x4 but...
