3500k is the color temperature of those LEDs. This is closer to red than blue. Blue is better for vegging, red is better for flowering. If using for both I think you did the right thing by going with the 3500k.
Quick question. I have a build planned for a cabinet I have made. I had a thread about it here https://www.rollitup.org/t/led-diy-build-help.927250/ but did not get much activity. I was planning on using Two 44" 5.886 profileheat sinks to mount (4) cxb 3590's 36v per. Looking at this thread I am...
Ya don't wire just one unless that amperage is covered by the cob (Seems these cobs have a max of 2760 mA). Those directions must be for parallel wiring. Personally I would get a new driver and wire them in a series. You could do parallel but I would suggest resistors inline on each cob if you...
Looks like the output voltage of the driver is 48v. The cob needs somewhere near 32v. (DO NOT Try the series with just one cob. Just looked at specs and single cob can't handle that current). Looks like the driver cannot handle more than 1 cob (in a series). Just looked quick but probably your...
Have you been training your past plants? SOG has value if u want quick flowers and plant count is not a limit. Usually would not be doing any training with SOG. Maybe just defoliating lower branches and lollipopping your colas. 40 g a plant would be pretty incredible. With SOG you could go...
Could have a hole in the reservoir somewhere. If that's not the case the pump might not be shutting off / closing. Based on your diagram if gravity is allowed to push water then it will flood through the plant pots.
