Hi Everyone, I apologize now if this question has been asked a ton of times but from what I've searched, I haven't really found a clear answer and hoping maybe some people could give their input. I have been growing for the last year or 2 (indoors in coco) under T5HO lights (yes I know...

So I ordered a kit 250 watt 5 cree cxb 3590s and it came with a meanwell HLG240H-C1400B. Works great.... I ordered another what I thought was the same kit but the driver this time is a HLG320H-C1400B, same COBS and all... if I hook this up and it goes to full power will this push too much to my...

I have a bar of 5 Cree CXB3590's running at max 250 watts, that I have just moved over the top of my seedlings. They are only about 2 weeks old so just little gals. I have the LED turned all the way down and up about 21 inches above them. When can I start cranking up the volume??

So I went to go continue my painfully slow upgrade from HPS to all cobs (which I guess seems like everyone is on QBs now?) I had bought Crees from timber before and loved the quality and great customer service and everything... I go back now and there are no Crees to be found on the actual...

Ok so I am currently growing in a 2.5 x 2.5 x 6 ft tent. I currently have an hlg qb100 4000k for veg cycle, but I want to add more light in the corners for flowering. My first thought was to build 4 cob led lights and put each in a corner. Then I found a thread about the hlg qb elite 96 and they...

I'm currently working on a light for a 4x4. The goal is to get a pretty even 900-1000 µmol m-2 s-1 across the whole space running it at 500W or less. The COBs are Vero 29, 3500K 80 and 90 CRI. I took some measurements with an Apogee SQ-520 today. At 40cm distance, I get a bit over 1k in the...

****Edit: The mystery has been solved, but the discussion continues. If you are looking for specific part numbers for your build, go to post #4. Everything is listed there*** Let me preface this by saying that I am still very much a green horn in the LED community. I am learning more...

Hello everyone. First and foremost, thanks for taking the time to read my post. I’ll give everyone a breakdown of my current setup and what I’m moving into.. I’ve never actually used a tent, I have always used a spare room for my setups. I currently have a 400w mh/hps ballast/reflector. I...

Hello All! We are a newly licensed medical grower, looking to get some opinions on a light setup. In personal growing I have tried many different LEDs and we are sold on HLG products, love the quantum boards. We have come up with several potential layouts, these three are the top picks. 1.)...
