cob

Hi guys, i'm new here. I've recently bought some chinese LED (6 led drived 31V 1,24A about 38W each), they are water cooled. I did some temperature tests. I can't solder the thermalcouple on these cob (they don't have it) so i just used an infrared thermometer (the cheapest on amazon)...

Whats up everyone?:lot-o-toke::welcome: Really excited to bring you this grow, featuring Remo Nutrients, and the same set up were rocking in the current BignStrange journal! For those who were part of that journal, thank you, and cheers to more insanity and fun! With that, lets blow this...

:Namaste: Hello fellow diy'ers I'm researching COB's for some time now and it looks like every build is about the same ... cobs run in series with a few meanwell drivers . My question is " is that necessary ? is there some science behind it? a paralel run would be less efficient?"...

Hello 420'ers :Namaste:, my second post here, asi posted the same question elsewhee on the forum on someone else topic but it seems to have gone dead. Been looking around for an active forum discussing DIY COB builds and this one seems to be very informative and active, so kudos ! Anyhow, im...

Hi all. Sort of consolidating some info gathered over the last few weeks into this post in the hope its useful to someone. Have posted bits of this in other threads over the last few weeks but have now had a good play with some COB leds I bought for testing purposes. So, long...

Does anyone know if there is a way to attach the Angellica wide reflector to the vero29SE? The Angelica reflector clip says that it supports the vero 29, but not the Vero29SE. It looks like most sites recommend the Stella lens for this COB, but none seem to pair it with a reflector. I did...

So I am trying to make my own cob light for my 2x2 tent. Been reading and apparently they are the way to go. Went to cob kits and was talking with someone and they gave me some I do on where to start. Specially on budget. Not looking to make something big so this is what I got. Please for those...

Im planning my DIY veg and bloom cob build for scrogging and I need some input from you guys. The lenses will protect the COBs from dust and damage, but it also remove some of the light and also focus the light to a smaller footprint, will that give me better penetration? is there any...

So here my new grow. 21 days into flower. I just removed most of my fan leaves. First time doing this. Also flowering in a 3 gallons hoping to keep a smaller plant but that didn't work. About the light. 3 cob vero29 from rapidled. Had to put up my mars reflector cause she just got...

Hey 420Magazine Users, I'm seeking for an answer from some experienced mates with COB LED Growlights. The thing is I'm going to grow in a 8 x 4 Tent (240cm X 120cm) and I'm not quite sure if my selfmade COB LED setup would be enough for this perticular space. Are 8 "CXB3070" at 1400 mA...

I'm tinkering with these COB LEDs with onboard drivers. They're designed for floodlight type use. Price is definitely good, IF they last. They're no-name Chinese, so they might not work out in the long term. I bought some 100W units in warm white (2500-3200K) and I'm going to do some testing and...

Hi, I'm new here. After reading a few threads, I got the bug to build myself a COB light. I'm a LONG time electronic tinkerer, so the electrical stuff is no big deal. I just needed to learn how to size CC LED drivers and figure out a frame and cooling. I'm not growing cannabis at present. I just...

I've been looking for a grow light to replace my 100x3w Chinese panel. From what I've gathered, i think this driver can run 4 of these in series? I'm pretty stuck and need some guidance. :Namaste:

Malawi Gold from Seeds of Africa was the first landrace sativa I've grown. For a landrace it did grew well indoors. Drying was a bitch. While the buds were firm they dried really airy. Twice I had to put fresh leaves in the jar to re-hydrate them. A trick a old grower taught me. It works...

Hello all and welcome to my journal. Here I'll be attempting doc buds high brix kit. I'll be using the perfect sun cob led for the first time. So let's get into more details. And sorry for not having proper grammar and misspelling as it was jot a strong suit lol. What strain is it? Femmed...

Hi All! I'm a on again/off again grower over a number of years. I've leaned most of what I know from reading Jorge Cervantes & Ed Rosenthall's grow books & have done reasonably well in a few different locations & situations. I currently have 2 clones vegging in soil under a 600 Watt MH...

What strain is it? Unknown. We will find out soon enough. Ya, I know it's not as cool as the awesome known strain grows out there, but is it really all about the genetics? Is it Indica, Sativa or Hybrid? Most likely indica or indica hybrid. Is it in Veg or Flower stage? Vegetative state. At...
