cob

Hello, guys. I have a 100x100x200cm tent with a cob 1800w light that draws 340w from the wall. I was wondering what would be the best light to add to it for an optimal yield. Plus, is it at all necessary to do that? I'm told I'd need to reach for at least 600 actual wattage, especially for the...

Hey All, I'm new to the forum, and new to the DIY LED Scene. My apologies if this is out of place. I started out looking at building a cob setup, and have started leaning towards QB's. I have no first hand experience with either one. The space I'm flowering in is 2.5' Deep x 6' Wide x 7' tall...

Hi Everyone. A close friend of mine approached me last September and asked me to help him setup his own grow. At the time he didn't have the resources to put anything together better than a couple florescent fixtures. So we set up a very bare bones op. Earlier this week he asked me to help him...

What is the best voltage/amperage to use when running BXRC-30E10K0-C-73-SE Vero COBs. The data sheets from Bridgelux uses 69.4 V at 1710 for 118.7 W. Would I run these at 70 W for efficiency or should they be run at what they were tested at? I originally planned to use two of them at lower amp...

I was a member here almost a year ago. Struggled with mental health big time after helping a lady with cancer. She died. I went on a bit of a downhill spiral. I have come back stronger, fresh and healthy. Even went 100% vegan 4 months ago. So, I did like it here and made some good online...
