I'm planing to setup a new grow tent, 80X80X200cm (2.6x2.6). which I'll use for growing two photoperiod plants in coco coir. I want to grow short plants , I'm not necessarily aiming for high yield but of course for quality yield. I want to go for QB and i have two options from two local shops...

I think a lot of people want these. Has anyone have the info as to when they will be available ? Has anyone settled for something different? If so...what? Is the difference between 3000k and 4000k that big ? Gratefully growing 3000

Hello guys, thought I would share my build and ask some questions as well. I've been in the middle of building a 4'x8' grow tent with all the good stuff. Right now I'm building my first 12 3590 cob LED grow light at 640watts and 2.8 amps. I have 2 drivers... each driver is 320watts and 1.4 amps...

Same deal, only thing that changed is I “upgraded” (more of a side-grade) to cdp 8852 and I have a 1/2” pickup that splits to 3/8” pump input. All my plumbing push connect fittings and tubing are atp or John guest. 4x4 560w Cree cxb3590 3500k 44 gal res High pressure aeroponics Greenleaf Mega...

Hi, I'm a Canadian (Ontario) prescription holder and I'm trying to set up a system for a 4x4 grow area with 4 plants. I'm also keeping an open mind to future expansion as I will be applying for a nursery/research license. My intent is to make an efficient lighting system while remaining behind...

I’m building a light using Samsung f Series strips and was wondering if anyone could tell me what spectrum was best to produce higher quality, 3000k or 3500k?

Is there a thread for pics that directly compare kelvin to kelvin compared to bud structure and trich production? If not let’s start here

Has anyone bought one of these kits? looking at getting 2 of them for a few plants in a 4x4 setup, not crazy about 3 cobs on a 20" heat sink. any input would be appreciated, hope everyone is having a great weekend. /vero29-triple-cob-array-kit/ sorry, not allowed to post a link. need one...

4 parallel COB's in a 4x4 tent with a light mover with the 2x HGL-185H-C1400B and 4 Vero 29 3500K "C" Could dim them down and bring closer to the canopy and the light mover could be used later for "further expansion" later down the road. Decent idea or a flop? Input and thoughts?

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...

Hi Guys Last Night I build up a Cree CXB 3590 2 COB Combo 3500K + 6500K for my Veg Box (0,6×0,6m/2×2) To fire up the Sun a MeanWell HLG-120H-C1400B with a 100k Poti (+/-3%=102.3kOhm) makes it easy to dim it up 102.3% with 3 COBs in Step 2 The COBs are active air cooled and 1.43A take out 99.8...

These seedlings are both about 6 days old, and the Ghost Train Haze #1 is the big one that has been vegging for about 1 month. I'm planning to top the seedlings at the node(forgot which Node this is) to create 4 tops and then flower them. I think the ghost train haze will be flipped to...

Greetings RUI community! Been living on here for a few weeks soaking up all I can from you amazing DIYers. I'm about ready to put together an order for Jerry from Kingbrite, but I am not sure about which drivers I should use with this setup. What I need is a super efficient setup for extreme...

clarify some things for me please. First things first, I'd like to thank you all for the knowledge that is being passed around. I've lurked on these forums for years, and LEDs finally got me to ask some questions. My goal is to increase electrical efficiency WITHOUT sacrificing flower quality...
