Hello All, This is my first post here and I have an interesting question for you all: I have seen a lot of static on the web about parallel wiring and current mirrors and resistors, but not much useful information. I know there are many different opinions about parallel wiring in our...

Hi, could you please help me to understand which is the best MW driver for 200-250W DIY cob led? I will use an arctic64 active heatsink(alpine 11 seems to be small) so 25°C may be not utopy. VERO29D need 37.2V at 1.4A 36.5V at 1050mA and 38.7V at 2.1A I' ve a 70x70CM grow box (2.3 ft) so i...

Hey guys, I'm trying to use rockwool stonewool blocks to germinate my seeds and I was wondering what size cubes I should start with the 1"x1". 1.5"x1.5", or 2"x2" cubes? I'll be using a 2'x2'x4' vegetation tent and 4'x4'x8' flowering tent, and was also wondering what size garden pots I should...

So I'm hoping you guys can help me. I'm new to this led diy build and have some questions. I was looking into cheaper leds bc well I can't afford full out set ups right now so I'm looking to do something smaller. Plus I'm only doing a 3x3 tent. And found citizen clu048 1818s. Then I found a few...

Hey all. I'm looking to do a DIY build for a 2x4 tent dedicated to vegging. I'm really into the idea of a Citizen COB build. Does anyone have some suggestions for what I should go with? I need driver and LED suggestions. For color temp it sounds like 3000k is best for veg only lights, but I'm...

So, finally getting the tent set up... For some personal reasons I cannot do a side-by-side comparison at this time of the Citizen 1825 80 + 90 CRI, which was my original plan in a 73 x 134cm tent (2x4ft), sorry Robincnn! I will hopefully be able to do that in the coming months for people here...

I'm planning on building a 9 cob display using citizens clu048 and 3 HLG-185H-C1050b drivers. I've got some dimming questions for you LED fanatics. 1) Will these drivers make any kind of electronic noises? 2) Will dimming these drivers make my drivers make some kind of noise? ^I'll be...

Here we have a Northern Grow Lights Photon 180 CLU1825 that @robincnn was kind enough to build for me to test. It utilizes two Citizen CLU058 1825 cobs in 3500k with 90cri. Just put the plants under the light and screen yesterday. Had these girls vegging for 5 weeks from seed under my 36w veg...

Hey guys, Breaking out the BOG gear with Sour Bubble and Sour Grape. The plan is to grow out 12 plants for a little pheno hunt so I can run clones later. They'll start under a 100 PLL fixture in a 3x2 space and after a longggg veg, move into a 3.5x3 flower room which will have either a 400 watt...

So, this is my first cob build, but not my first DIY light. I built to a modest budget, and chose Citizen over Vero 29s after crunching the numbers and realizing Citizen is way ahead of Bridgelux at the moment, likely because they are a generation ahead right now. These are a minimalist...
