Just grabbed these cree initiators and rapidled 4x4 canopy substrate with 3x rails. Now i Just need a good led controller to wrap up this cob array. Anyone know of a good cheap way to time the initiators? I'm already over $1000 into this 4x4 cob rig now that I've added these I can't afford a...

That makes me happy to hear because I started using a cob array last month. I have 18 cxm-22 3500k 90cri cobs over a 4x8 area. If i run them soft at 1200 watts I get 37 watts per square foot. I can run them as high as 1680 watts for 50+ per. I haven't added any flower initiators yet though. I...

Ahh all mine are from Taiwan. Must have all been from the same batch I guess. Either way not all Asian made electronics are bad, meanwell is top of the line, so is samsung, and many more names not at all associated with "cheap chinese" if that's what you're point was. Being new here is...

Meanwell is from Taiwan, not china...

A roll of 16-2 For long runs between driver and cobs, or 18-2 Like he sent me for short runs is fine.

You could even add more cobs by daisy changing wagos but there are far more elegant solutions for that

You need one wago for positive and one for negative or you'll just short the driver at the block. So 2 per driver per 4 cobs

I'm going to add an inline 5 amp fuse since the driver is rated at 4.8 amps. I also want to put a toggle switch on each cob to allow individual testing/maintenance without interruption of light, making them hot swappable

I salvaged a power jack from an old computer power supply for each of my drivers that also had a 15 amp switch for power and a ground connection to ground the entire setup. Beware the setup I am posting pics of is extremely rudimentary, I had some scrap metal around and wanted to just slap...

You can run 4 cxm-22 in parallel on each hlg-185h-48a driver with 2 5 terminal wagos / per driver So: 8 x 5 port wagos 4 x hlg-185h-48a meanwell drivers

I'm running 2 5 port wagos per driver, since I have 3 cobs in parrallell on each driver Growmau5 has a video on how to complete your light with red supplements. You will also need meanwell drivers, Cobkits sold me one hlg-185h-48a driver per 3 cobs, so a total of 6 drivers for the 18 cxm-22s...

I can't comment in regards to temperatures yet as I'm brand spanking new to COBS and whatnot, but general consensus seems to say that 90cri, while requiring more wattage to produce the same output, is far truer to the suns spectrum and results in much larger yields

I concurr, I received the parts for my 18 cxm-22 "engines" from cobkits and it took me less than an hour to assemble all 18

That was me lol

So just to update this, today the 3rd and final package containingn my cobs and parts arrived from CobKits.com Construction is taking less than 5 minutes per "light engine". Everything was packaged perfectly I couldn't be happier. Definately glad I chose to assemble on my own and avoid...

Last package arrived today. I have some assembling to do but now I have all 18 cobs, 130mm passive pin fin heatsinks, 18 bjb holders, 6 MW hlg-185h-48a drivers and 12 wago 5 terminal blocks. Yeehaw I'm off to the races!

4x8, I ended up getting 18x cxm22 3500k 90cri

So just to expand on this, 24 hours later all 15 seeds have not only cracked, tap roots are already protruding. Holy crap every single one germinating flawlessly faster than any seed I've ever planted. If this is any indication of quality then I can not wait until these girls are ready to harvest

I'm already on that page man. About to be on my 9th blunt today

If he had never chimed in, my experience would not have pointed to him. It couldnhave been my own personal experience and reasoning behind my point that sourcing from the manufacturer saves time, money and hassle. Y'all created a witch hunt out of it, and now you think I'll swallow your pill...
