Hello fellow green (or shades there-of) thumbs, I would like some feedback on the layout for these flood-and-drain style growbeds in a soon-to-be-built 20’ greenhouse. Half, that’s right, HALF of my current food budget goes to salads, so lettuce/cucumber/tomato are all very important for me.
Water will be pumped constantly from my ~1000 gallon rainbow trout pen which will also supply the nutrition. I’ve done some aquaponics in the past successfully, but this is my first stab at a larger setup and my first greenhouse, so all critique is welcomed.
For a 1000 gallon trout system, you’ll defintely want more than just root filtration. Trout produce way more solid waste than tilapia. I’d recommend a radial flow settler before the growbeds to catch solids - otherwise you’ll get clogging issues in your flood/drain system. Been there, done that, had to rebuild my whole setup lol.
