cob

Hello guys I need help from you. I've read tons of stuff about led lights, cobs and qb's. And I want to start growing on my own. I have unused cabinet 50x50x100 (or 120) which I want to use as grow box. Planning on growing 1 (max 2 plants if I get wider box). Question is what light would be...

Hello, im New to Led Grow. This one im using a fixture with 2 cxm32 running low. Growing media os coco, nuts from canna. First days everything looking nice, one week pass and leaves are getting some spots. Im wondering if anyone can help. Thank you

I have decided to build a veg tent to accompany my 4x4 flower tent. I have been using a MH/HPS setup, but I'd like to explore other options. I am building a 2'x4'x6' tent setup (could go for 7 feet tall if needed) and I have heard about cob lighting but I'm not sure if its actually more...

Hi All, i am planning to diy a cob led. I have decided to go with the BXRC-35E10K0-D-73-SE, 4 of them to run in my 3X3 tent. My doubt is i have seen people asking not to drive COB's at higher Amperes. The max current for this LED is 4.2A. So if i am using a meal well 2.1A driver, is it good to...

Looking for suggestions on budget LEDs, COBs or quantum boards with decent efficiency? Looking for about 15% blue in the spectrum.

Just upgraded from a giixer 1000w to a sunraise sw3000 and a sw1000..... It is quite a bit heavier than my previous light, my room has sloped ceilings and two studs that run up and down I have hook screws in the studs already for my giixer, was wondering if they will be good to hold the sunraise

Hey there, random rollitup dweller! I found these LEDs while browsing AliExpress for my diy grow lights. Reviews are pretty good, but I can't really believe that you can buy 50w cobs for a couple of bucks (especially knowing how much they like to exaggerate specs on the Aliexpress). So the...

These things are absurdly awesome! Here's my vid review with half-assed PAR readings.

I have 8 clones in solo cups with coco and 2 of the clones have this taco going on. I’m using 1 60 watt autocob about 3 feet above the plants. Using RO water and cropsalt veg nutrients ph 5.8 ... could this maybe be from the coco drying out too much between waterings?

So I've got 16 COBs in a 10 ft x 10 ft room. Canopy is roughly 7 x 7. What I've got running is 2 rails of 4 trusty dusty clu048 1818 in mixed spec of 3000k and 4000k running off the bad bitch hlg 320c 1400a. 4 on a rail, 2 rails, 4 ft each. Cobs spaced evenly apart about 10 in. on center. Then I...

Hello Rollitup! I need some advice please. I am planning to build a grow room with COB lights and a no-till bed. I need help determining how many plants I should fit in my space, and how much light I need. It is not my first time doing COB and no-till, but quite some time has passed since I last...

Hello this is my first real grow that I have planned and spent a little money on. Thank you for dropping by and if you have any advice please feel free to share it. I will start by saying that I have grown before, but it has always been under less than ideal conditions and I have never had the...

FIirst off, I'd like to thank all the people who contribute to this board. So much great info that I can hopefully add to with my build and grows. I'm getting into growing since I got a medical card. I plan on producing mainly to make into bubble hash. For my light, I was leaning toward going...

Greetings riu! I'm adding a 5' x 5' tent to my area, looking for advice on how best to light it up. I need relatively low heat of LED, but also want to take advantage of the UV and other benefits of ceramic metal halide. Buildasoil has a combo deal with a 315w CMH + (4) x 100w COB fixtures...

Yes hello ! I am exploring some different led options and having some fun in doing so !!!! I love to grow it’s so therapeutic and I love to think about different LED light setups I could do. So I am wondering if people could chime in on some led strips or quantum board strips or module strips...

I normally just grow a crop out from seed through to harvest, but I want to setup a perpetual grow. I veg for 2 months and want to save as much electricity as possible. There is a 75W COB and a 70w QB . I understand that COBs have better light penetration and QBs have a wider spread/less heat...

Hey everyone I just wanted to show you guys a mod I did on my Viparspectra PAR blurple lights to turn them into COB panels. The light in the picture is a viparspectra par 300w (~130 actual watt) blurple panel and the COBs are CREE CXB3590 4000k 72v 90cri. The power supply in this light runs...

Hello everyone, just joined and wanted to show you all my setup which I’m pretty proud of so far. Running my second grow currently that I switched into flower about a week ago. In one 32”x32x60” tent I’m running ~550w of viparspectra blurple that I used my whole first grow and in the other tent...

AuraLux 300w LED Grow Light Spectrum Cree/Bridgelux https://www.amazon.com/dp/B071S7S7X8/ref=cm_sw_r_cp_apa_i_ZT0yDbD4QEHV5 People around me have absolutely no experience with LED and I've not found anyone who has grown with one of these Specs. 1x cxa2540 veg cob 4x 5w bridgelux smds I think

Looking to start a new experience with a.cob led grow ,probably a bunch of 50w ,probably 6-9 Wanted to ask a couple of questions are driverless LEDs useless as some people go on ? Quite confusing as the grows and articles based on research show otherwise Also is this due to the efficiency...
