@GMan

What is e&f? Ebb and flow?

Yep, you got that one right.

@GMan

connected to a small reservoir?

Sure is, 8 gallons fit below the upper tub.

@GMan

you have an airstone in the system?

No, but I might add one.

@GMan

Is it a build or an all included unit? It seems all self contained??

I built it. I have a few posts in my workshop thread starting here where I painted the two containers.

ReikoX's Workshop

Got a little E&F setup I’m working on. I wanted the opaque version if these totes, not they wanted $79 to deliver them at Lowe’s. So I got the clear ones from Target and some spray paint. First I scuffed up the plastic with some 400 grit sand paper. Then I coated the top tray in white and the bottom resivoir in black. After that was dry, I flipped it. The top tray got a few coats of black and the bottom tray got a few coats of white. [image]

Then assembly

A little more progress. I laid out the holes for the drain and the flood. [image] Using a hole saw I cut out the holes. The big hole is my drain/fill hole, the small hole by it is the fill/drain, and the one in the corner is the overfill. [image] I accidentally broke the plastic drilling it, so a nice coat of silicone will solve that problem. [image] I installed the fill/drain, then cut out the screen and did a dry fit. [image] Looks like I’ll be able to get a dozen party cups in her…

And testing

ReikoX's Workshop

Got the E&F finished. The first time firing it up. Worked as expected, it leaves a bit of water after the drain cycle though. The drain could have been in a slightly lower place. [image] I filled the cups up with coco chips, reused from the FAM project. Again it flooded with no floating pots or spills. [image]

Finally installation

ReikoX's Workshop

Doing some CAD (Cardboard Aided Design). My floor in the cabinet is set up about 4.75 inches. I will need the extra space, plus keeping the reservoir on the cold concrete slab should help keep temperatures down. [image] First I measured and traced out the shape I needed to cut out. [image] Next I drilled the corners. [image] Then I cut out the floor using a jigsaw. [image] A perfect fit! Well almost, my sight line is higher than my max fill line… [image] Mixed up some nutrients fo…
