So what do you recommend for my set up for 5x5 tent? I'm thinking 12-15 COBs but can't decide on type/number of drivers. Thx

Thanks bro you’ve been a great help!

Thanks bro. You’ve helped plenty

Interrsting. So what is the added benefit of going up to a let’s say 2400mA vice 1400 driver aside from putting out more heat? Do you get much more photons etc or is 1400ma sufficient?

Hey man, thanks for the reply. At 1400mA, your running the cobs at less than half their rated current. According to the data sheet, at 1400mA, the cobs are running @roughly 34v. The driver in the picture has a range of 89-179V so 34v x 5cobs= 170v. 170x1.4= 238W. What happens when you dim all...

Are you running them in series or parallel? Also, what drivers and heat sinks are you using? Much appreciated

That’s awesome. You recommended earlier COBs all the way. However, I see your using QBs as well. Do you mind explaining why your using both? I’m not sure if I should go COBs all the way, QBs or a combination of the two. Also, if I wanted to go with your set up, either COBs or QBs, what/how many...

What kind of heat sink would you use? If I was to spread them out, I’m guessing 2 QBs positioned on top of each plant would do?

Can you post a picture? Did you use 3500K all the way or did you mix them up?

o_O Not sure how this thread took a wrong turn!

Hi all, I am new to the site and hungry for some feedback. I’m starting a set up and before make any purchases, I wanna do my homework. I have a 5x5 tent and plan on growing 4 plants using coco in AutoPot . I’m wondering if I should do a mix of COBS (cree cxb3590) and QBs (304 or 288). Looking...
