Quick question - if using a MeanWell HLG-600H-54B Driver with 10 Luminus CXM22 3000k 90 CRI COBs, with the driver running full blast (Either the potentiometer all the way open or not connected at all) how many watts from the wall would out be pulling? I'm coming up with 576.8 watts, and how...

Wow, GLR! I'm with CobKits - your info is flawed at best, and to come into someone else's thread and saying that is rude, uncalled for, and just plain ignorant. Go into your own thread, discuss your way and ideas, and roll out of this one. *.*.* Cedru *.*.*

Little offthe current topic, but I see the RIU coupon code has expired on CobKits.com. Any replacement available that I'm not aware of yet? While I'm at it, here's a little New Year Video thrown together using all COBs, drivers, and heatsinks purchased from CobKits.com. COBs are 8xCLU048-1212...

@CobKits - any idea when/ if you will ever get the qb304 in 3000k in stock? Thank you, *.*.* Cedru *.*.*

@CobKits what are your recommendations for a 5' x 5' x 6.5' FLOWER ONLY tent? I already have most of my veg tent complete, placed the next to last order today - so now it's time to prepare for flowering in 2 months. Quantum boards or COBs? How many of each and which driver(s)? Thanks in...

Well that makes a whole hell of a lot of sense. Guess it's in parallel the go, until the new driver comes in. According to the specs, it pushes out 8090 ma, so I'm guessing I can run 7-8 of these 36v cobs at ~1050ma safely in parallel with this current driver safely, correct? Thank you...

Little help needed.... Got a Mean Well 320H-36b driver. currently NO potentiometer hooked up to it. Have 2 cobs, Citizen CLU048-1212 properly hooked up to their heatsink. When wiring just one cob from the driver, brown driver lead to positive, negative to blue driver lead, the cob powers up...

Ooh yeah, very! Of course I only let it inn for a few seconds each time, but yeah, vey bright.

Only problem is these hat sinks are out of stock on HLG. Any idea when more will come in? Thank you, *.*.* Cedru *.*.*

Aargh.... Just got used to learning about COBs, now I need to put a learning on quantum boards. anyone have any quantum board DIY build Suggestions for a 5'x5' flower area? Height is approximately 6', in a basement - heat won't be an issue. Will be grown in 5 gallon buckets in coco/perlite...

Using Coinbase is easy. Once you have your wallet funded, go to "accounts", click on send (in the app, bottom left corner, looks like an arrow) and copy/ paste the seedsman id and then the amount. Hope this helps *.*.* Cedru *.*.*

Please tag me when you start it up, as is like to follow that!

That, my friend, is extremely informative. Thank you so much sir for the detailed analysis. I'd still like to see a side by side comparison between a 6500k/2700k veg/fower grow to a straight 3000k or 3500k start/ finish grow. Since I plan on getting two sets of lights, one for veg, one for...

So, hypothetically speaking, if one were to set up a perpetual grow, one area for seedlings/veg, another for flowering, using all COBs, it WOULD be beneficial to go with a higher spectrum set of lights for the veg area, and a lower spectrum of lights for the flowing area. You'll be buying the...

A little help would be appreciated in clearing something up for me. "Back in the day " we used a higher spectrum (mh @ 6500k) for veg stage, then went into a lower spectrum (hps @ 2700k) for flowing. Now with these COBs, I see a lot of recommending of a straight 3500k. Wouldn't it be more...

So, if I'm correct, both of the drivers I mentioned in the original both have an on board dimmer that I'd be able to lower the amps out to 1.4 if I see any burnage on the plants. This 9 x 36w x 1.4a = 453w / 9 = 50 w/sq.ft. if someone could help me with the ppfd for this, I'd appreciate it...

I'm only coming up with about 680 watts, not 1000. 9 36v COBs x 2.1ma = 680.4 3' x 3' = 9 sq.ft 680/9 = ~75w/sq.ft. Am I miscalculating or doing something wrong? Also, forgot to mention in the original post, all plants will be the recipient of Low Stress Training as well. Thank you...

Ok guys - any introduction is in order first. Been a grower but with CFL/Floro and Metal Halide (Veg) and strict HPS (Flower) Long time lurker and learner here, but now I'm wanting to start trying a perpetual grow with LEDs, specifically a DIY COB setup. So, I run 9 plants at a time, in a 3' x...
