New to LEDs and these two companies stand out to me. Saw some good opinions, some bad. mostly claims that you can build something with the similar spectrum and intensity's for less. but I'm interested in something with a good size footprint (5x5), full spectrum, controls and timers, low heat. I...

So I've been reading up on heat pipes, which seem fairly simple to make and are well explained in this video. I noticed that baseboard heaters have a 3/4" copper tube with aluminum fins already on it and people are regularly throwing them out. You just need to buy some copper fittings, try...

Hey guys, so Im looking to build my first DIY COB set up and I wondering if I should try and run 9 COBs or 6 COBs ? My plan was to run 9 to have 1 light every sq ft but Im having trouble finding a driver that would run all 9 COBs in series. Would I be better off doing 5 COBs on 1 driver, and 4...

Soooooo I was shopping high (big mistake, never again) and I bought 2 cobs, 1 is 36v, the other is 72v. The drivers i got are HLG-60H-36A so its not gonna run it but LUCKILY i've got a spare HLG-60H-36. I'm guessing fusing these two drivers (HLG-60H-36A & HLG-60H-36) would make it possible to...

Hello. I am planning to build a new grow room and I would appreciate some advice. I've done a fair amount of research but there are still some things I don't understand. Technical terms, maths and physics are fine by me. Grow space size = approx 13ft x 13ft (4m x 4m) but i don't need to use...
