cob led

Good day guys, have been use COB panel for few months. I can see some dust on the lens this might reduce the efficiency of the LED. If you use COB panel, How to clean up the panel to make lens clear as possible without duct as possible? Expect for a little pricey, I love COB led. Im using...

Some of you vaguely know me from the way. I don't think I've ever seen buds frostier than mine, and I say that not to boast, but to encourage you to walk away from brand loyalties and push your abilities beyond buying authority. I use the Jack's Professional Hydroponic 3-2-1 formula from...

i was all set to build a grow light similar to the kind k4, ie with separate light spectrum leds, and i started seeing cob grow lights. i have a question regarding these two types of led grow lights. i kinda liked the fact that with the leds you could control each color individually, and i...

Vitaly is a guy who just kinda seems like a genius who built some of the best looking lights I have ever seen. He's got a great set of playlists on YouTube. I just purchased 6 of his PCB's for a DIY build I plan on doing for a side by side. We're going to see how these units stack up next to a...

So, I have been a member here for a number of years. I have stopped in sporadically over the years for advice and now I'd like to give back. I'd like to chronicle my latest project- switching over to COB LEDs! A year ago I ran into these guys from ProMax Grow. They had a light priced around...

I'm jumping on board the COB train and am prepping a build for final wiring and completion. But am wondering , from those that have run their builds whether 3000k or 3500k COBS are what would be the best ( overall kelvin temperature ) for growing start to harvest. I have a 5 COB build with a...

I just wanted to see if anyone else has heard of or bought one of these types of boxes? We are a new company trying to get feedback from customers, even if you aren't interested in buying one take a look and critique our setup! Thanks in advance! Here's a link to the listing: Fully...

the objective of this grow is to try to get a cheap effective grow with consistent results also being able to have a perpetual harvest in a small space. starting with one plant this grow is a test to try to get everything down to a system that is cost efficient yet ends up with a good result...

Hey RIU, First off I would like to thank everyone for all of the valuable and interesting information found inside these forums. I am a big fan of many of your grows. Now lets get into it. I currently have 4 plants that are being grown in a 4x4 tent under t5h0 6 bulb 2 ft long veg light. I am...

Hey Everyone! I'm back with another grow journal and in this journal I will be doing 2 grows at the same time. I will be starting one tent in flowering and the other tent I will be doing a full grow from early veg to harvest using new white cob led technology. I'm running some new strains which...

Pictures below the following wall of text. Plan: - Two Jack 47 F1 Fast (Jack 47 x Jack 47 Auto, PHOTOPERIOD). Seedling 1 week, veg 3~5, bloom for 9. There have been a few soil grow journals online for this plant... I think I'm looking at 55-65 days of bloom. With half a square meter of space, I...

Hello friends, they call me Teff and this is my first venture into LEDs. After doing some reading and video watching I decided to order some things to get my build started and I was hoping I could get some assistance with filling in the blanks. Tent: 20"x36"x62" LEDs: 5x CREE CXB 3070s Driver...

Hi Everyone, I've been lurking the forums gathering information for the last month or so and would appreciate some advice. I'm looking to replace the Mars Hydro Reflector 144x5 I have in my flower tent. What's the best I can do for around $500? I've looked into building my own but the task is a...

Hey guys... so I have a P150 (continuous spectrum with 50w veg & 90w bloom). Last grow was my first grow and it went fine... got 3 oz of shit weed and 1 oz of pretty good stuff from autos. Veg was good, but I'm planning on adding 40 watts in bloom. I have currently purchased...

Hey guys I've been lurking around here for a few months now, slowly ordering everything I need to build a COB setup. I have most things figured out due to the immense amount of information on this forum but have ran into a couple of questions that I cant find answers for. First of all, I...

Hey Rollitup community, As many here I'm thinking of giving a try to DIY-build COB LEDs. So i started reading datacheets, comparison charts and even dummy electrical engineering books (as my knowledge of current electricity and circuits is not that good since highschool times hehe). So i set...
