Parts have started arriving already for my first cob build. I am an absolute noob when it comes to building lights but you can see the bud I'm growing elsewhere :) Parts sourced so far (some have arrived. Some are on the way) Meanwell hlg320h c700a driver. 5 x citiled...

Wanted to see what one of these LePower Amazon LEDs can do. $50 for 100w light, 6000k, 107w at the wall.

I currently have a 4x8 grow room i want to start a new grow with led lighting. I want to start my veg using 4x4 of that space. Later utilizing the full 4x8 for flower. My question is what would be a good set up for my 4x4 veg space. When its time to flower I'll add more lights . I'll be growing...

I have had the worst luck getting anything going at my new pad. Water problems, soil problems, temperatures too cold, ph pen fucked up.......had to get rid of 5 plants that were a couple weeks from finishing up. The list goes on and on. I'm hoping that I have things lined out and I'm going to...

So my 20+ year old soldering iron gave up the ghost, it was an old POS from back in the college days and am amazed it lasted this long. Alas I am not familiar with the latest in iron tech so if anyone has pointers that would be great. Seeing as this is prolly the last soldering tool I will ever...

I just discovered that I am better off doing a grow journal in this forum as a thread, rather than using the 'grow journal' feature. These are 3 blueberries from Seedsman, currently finishing week 4 of flowering. Two were 'mainlined', and the third was 'fluxed'. The veg period was for 8...

Hi, i have a CXB3590 3000K fixture as my light but also have an old Mars II 400 - would the Mars be better for vegging? specs are 440nm, 460nm, 630nm ，660nm,730nm(IR), 2400k-3000k thank you

This is my first time using cob lighting, which I feel shits on my previous cfl lights. It's a work in progress. I have 4 CXM22 3500k 90 cri Cobs driven by a 240h 54B meanwell driver on a frame I constructed. Ideal holders/adapters, Angelina reflectors, 120mm sinks, 100k pot, wired in parallel...

Hello to everyone! greetings from Argentina, i decided to make some investment and buy some cobs , here in Argentina there is no reseller of cree or bridgelux, so i have to buy them in the US, the only driver that i can get here , is the Mean Well HLG-240h-c700A, voltage output max is 357 v.

I thought i would share some photos from how my first grow is coming along and see if anyone has any advice. I'm growing 2 plants in a closet that is 500mm x 1200. Im growing 2 strains, durban poison and the other is a green crack. About a week ago i put them into 27 litre (7gal) fabric pots...

I'm just going to start a thread on my newest grow box build, and first real "stealth" attempt. It's just an old crappy dresser with dimensions of 3 1/2ft L x 17in W x 47in H. I plan on throwing my new cxm22 cob array in there, which should be plenty of light. About to go pick up some beer and...

Anyone build a successful rig using direct AC powered IC LEDs? Searched the threads and found only three hits; not much enthusiasm it seems. However, given the price and ease of setup, I suspect this new breed of LED will be the preferred LED array setup in the future. $30 plus for 1 Cree COB...

Hi, i am new to cob lighting i have been researching online and am getting ready to buy my first setup, i have only ever grown using 600 watt hps/mh lighting, i am looking to get a cob setup that can replace a 600 watt hps light, my space is limited so i only need to cover a 3x4 tent, how many...

Howdy, Converted two mars2 panels to 3500k citizen clu 1212 for flower, looking to convert my other two panels over now for my veg light. Was thinking 4500k off the top. I've read all the spectrums between 4k-5k are good but wanted to know what you all found to work best personally. Thanks!
