Right on, you might want to look into using fans to cool those heatsinks. These COBs can get pretty hot if not properly cooled.

Sorry I haven't been updating as much, but I did just switch back my lights to 12/12 yesterday, so now that the flowering period has begun I'll begin posting more. Veg updates just aren't nearly as exciting. I still have 2 plants in my setup with a C99 and a blue widow clone.

Yeah, go by what the forward voltage and current is instead of what the driver says because even it says it's a 50W driver, it might not run a CXA3050 as the current could be 2A and voltage could be 25, which would not run a CXA3050 even though that's 50W

Actually my driver can output anywhere from 37.5W to 60W. The voltage range the driver offers is from 25-40V at 1.5A. So it's not rated for only 50W, just that's what a good use for it is. The meanwell hlg-100-42 is a driver that can adjust voltage and current and the max current of that...

Meanwell sells drivers that you can adjust the voltage and current so you could have them set to run at 50W and drive them all the way to 100W if you wanted to. I've thought about adding these at some point because it would be pretty sweet to overdrive them a couple weeks mid flower. The...

I just wired them up directly to the driver. The LEDs can be run all the way to 100 Watts. Each LED is pulling around 55W with the drivers I used. As long as you have around 36-40 forward volts you can run these LEDs with a wide range of current.

No need for a breadboard if you are using COB leds as you just mount directly to heatsink and solder as they come directly on the pads ready to go. I only see the need for a bread board if you were using single diodes like the cree xm-l

Those should work just fine for the CXA3050 or CXA3070

About 4-5 degrees Fahrenheit. There's actually a formula you can use to compute how much CFM you need to keep a desired temp for a given cubic feet and total watts.

The nugs are dense and the smoke is great. Makes my wife giddy all day. Blew away my previous DS100 light. Not to mention the smell is really strong. One tiny nug stinks up the whole area. Considering how small my area is, I think I would be hard pressed to top my output. I pulled 4oz's...

Still a lot cheaper than purchased lights. My first 100W led from advanced LEDs cost 300

Thanks. I am still sticking with Hempy. I can't discount the results I get with it as well as the simplicity.

Yeah, I'll be doing a 2 plant scrog soon enough and that should make for some amazing yield numbers

After 5 days of drying the preliminary weight is 126 grams. I expect it to drop a little more in the next few days, but I should still hit the 1 gram per watt.

I just got some 50W led drivers off ebay for $17 a piece. If you go to the beginning of the thread you can see them These LED buds were on par with any HPS buds I've grown in the past.

By the way my outer dimensions are approximately 25-3/4" L x 19" W x 35-3/4" H I built the cabinet using the Sterilite 2 Shelf Storage Cab. I copied a link below http://www.walmart.com/ip/Sterilite-2-Shelf-Storage-Cabinet/8206250

Ok guys, time for round two. Just put in my baby C99 from Female Seeds. Let's hope round 2 goes as well as round 1 did. P.S. The Blue Widow might be one of the stinkiest plants I have ever grown.

I only used 2700K throughout the entire grow. Honestly don't think I would have benefited from the 5000K because these nugs were so dense and the plant vegged fantastic as well. I think 5000K promotes too much leaf grow and these buds were about the easiest to trim as the flower to leaf ratio...

1 per sq/ft would be ideal. Depending on how many would want to run, I would look into a 300-400W power supply, then use buck pucks for each led. So everything would be run off of one power plug. Meanwell sells power supplies and puck drivers.

Chopped her down yesterday. Will post dry weight by end of week Don't mind the toilet in the pic as I got them drying in the dark spare bathroom as that place does a good job handling stinky things :-) The size and denseness of the nugs are just unbelievable for such low wattage.
