And personally, i dont like cree. They tend to be difficult to find drivers for, and i feel like they dont work as well for flowering. The new decor series vero29 has a cri of 97 and the trich development of my buds is insane. But thats just my preference haha, all leds are good though, evwn the...

Order your driver's from jameco.com electronics store, and your chips from digikey.com and order your heatsinks from heatsinkusa.com

Check out "growmau5" on youtube. He does a lot of tutorials on led building, hes a little extreme though

Oh man i hope you can too, i have made the same mistake though so i know what you are going through. I wish they told you what drivers to buy when purchasing the damn led's haha

This driver outputs 71-143 volts 200.2 watts 1.4 amps ( it will run your chips a little harder than 50% but theybwill still be very cold to the touch and very efficient

Buy this driver, meanwell HLG-185H-C1400 b. It will run 3 of your cxa3070 chips no problem, i swear

No, if you ran 1 cob, you would over load its max wattage and blow it up or cause a fire. You have the wrong driver my dude, your driver is rated to put out, (5.8 amps, 36 volts, 187 watts) this will not run any amount of your cxa3070 chips

The 187 watts would work for 3 chips but they wont be very efficient, but your driver only "outputs" 36 volts. You need a driver that has an output of "115 volts"

Your driver also puts out way too many watts. The idea is to run the chips at half their max wattage in order to make them more efficient and run colder. Powering an led at or close too their max potential makes them no more efficient than a standard incandescent light bulb

Its confusing stuff i know but trust me, i build these all the time

You need more voltage not less

You said you were running 3 cobs per driver? If you run 3 led's off of one driver, then the drivers total voltage output needs too equal the sum of all 3 led's voltage together. The cxa3070 runs at 38.5v and 117 watts, so you need to do the math, 38.5×3=115v and 117x3=351watts 351÷2= 175.5 So to...

You do not need the dimmers to be hooked up for the system to work, they are not needed to complete the series. Your lights are not working because they don't have enough voltage powering the system

According to my calculations, in order to power 3 cxa3070 chips, you need a driver that outputs at least (175.5 watts) and (115.5 volts) and preferrably (1.9amps). Your driver is currently only putting put 36v, your driver's voltage needs to equal the sum of all the combined led voltages...

The first thing to remeber when choosing a driver to run your led(s) is to make sure that your drivers output voltage is equal to the total sum of the led(s) being driven, and the total wattage output of the driver should be equal to at least half of the max wattage of the led(s) in question.

Maybe i received a bad batch of it? No light gets into my res, and i dont think its algae (dealt with tons of that in my fish tanks lol). Its just this odd clear slime with an earthy smell that i get when using sm90 and hydrogaurd, but when I use just h2o2 it stays fresh and clean.

I tried using hydrogaurd and i didnt like it, it gave me a bad slime problem as well as a bad smell, has anyone used chlorine instead to keep the system sterile?

Just to keep a sterile system, i usually add some peroxide every few days to ensure i dont get root rot or slime. My friend recommended i use sm90 instead of peroxide to keep a sterile environment. I drained my reservoir, flushed with fresh water, then proceded to fill my res with fresh ph...

Ok so here is the scoop. i have a 4 bucket ebb n flow system, i started adding sm90 (as advised by a long time growing buddy) about 3 days ago just for precautionary measures. I have noticed a not so pleasant smell and a clear/white slime building up and floating around, anyone have any ideas...

i googled what happens when you inject nutrients into the stalk of the cannabis tree and that was the first link that came up haha.
