I tried to find this out reading the thread, but it's so very long, I got 35 pages in before I couldn't take it any more...
I need to figure out a good way to connect the CAP Ebb & Gro Controller module (haven't bought yet) to my 3 flood trays sitting on 5" wood blocks on the floor of my tent. I currently have the standard flood/drain bottom drain openings, and they are currently blocked off since I'm not doing flood/drain any longer. I am currently top feeding with 1/2 hosing, and using a Shop Vac to remove excess nute solution.
I want to run a 50-100gal rez that will feed my (3) 3'x3', 5"-6" deep trays, each containing (10-12) 2 gal root pots. I'm not sure how to calculate the amount of water the rez will need to hold, and whether I will have to drill side holes (and use grommets) in the flood tables instead of using the bottom ones. As I don't have the actual unit to inspect, I want to ask you guys for your thoughts on what I will need to do to keep the trays from overflowing.
Perhaps I will need to raise or lower the trays, or set the controller bucket up on something that's the correct height, so that it's overflow float will match the overflow height of the trays.
Any thoughts appreciated.
