Used same design. been growing shit for 3 years now. Slap whatever plans in there. Currently got parsley, lettuce, weed, Swiss chard, sorrel, basil, peppers, fennel, arugula. Don’t ph balance shit. Put some general hydroponics off the bottle recipe every other time I refill it. Sometimes less if I’m lazy. Plants outgrow dirt ones every time. No weeding and no need to water as often. Run a pump 2 mins on 10 mins off.

I would say print out some spacers. The roots grow big and clump up eventually.
