nice setup.generally we see a center hotspot with symetrical builds like these,but you have an empty spot not in the center where the qb288 goes.i think leave that out or plan to run the fixture higher.if it was me i would put 4 qb288 on the corners and use the qb132 in the rest of the spots.but this will work great also.sorry,you asked for thoughts/suggestions lol.in the current setup i would use nothing in the center or put a qb 120 or qb132 in that spot and keep it dimmed a bit.
That’s exactly what I was looking for actually. I thought that the 8qb132 would be enough, but it’s easy enough to upgrade when I do my cob/Cree add on. I had not thought about the heat generated in the center- good call, and I have more qb120s so I could throw one in the center. I predrilled the frame to give me more configuration options. I was hoping I had built myself a system that was more than enough for the space. 8x75+60=660w at max draw? I’m super confused of equivalent light comparison vs power usage. Do these boards create more usable growing light per watt than what I’m used to (mh / hps) ? I have read enough bs but this is my first step into leds as grow lights. What should be my expectations?
When I said hotspot I was referring to the extra par in the center not heat haha.if you wanted perfect coverage I would add a QB 120 to that center location and drive it slightly lower than the 132 boards are.i believe this will put out a very even par across the tent.as far as these LEDs compare to standard hps,you only need about 600w of quantum boards in a 4 x 4 or 5x5 tent to get the same par you would from a 1000w hps.450w of quantum boards will spank a 600w hps.750w of qb rivals a gavita .
yes.as for the other stuff idk :happy:I should get similar results with a 132 in center and dimmed?
