I am having a minor issue with getting even flow rates out of the nozzles due to some sort of clog or air bubble trapped somewhere in the splitter, despite repeated attempts at cleaning/purging. So for now, no direct experiments, just some home grows to work with.
I've started with some Parris Island Romaine on the left and Bloomsdale Spinach on the right. I did not have enough rockwool to propagate every channel, so each channel has four rockwool cubes, for a total of 12 plants per side.
The spinach is under my old prototype 50w quad-band + white. The lettuce is under my 50w tri-band research panels.
