It’s not that tough, just instead of keeping plants alive you ar keeping fish healthy and buying fish food instead of fertilizer. It’s not perfect, you have to foliar spray some things that aren’t in the fish poop (magnesium, trace metals) but when you do, the results can be spectacular. You might find it easier than the chemistry dance of hydro twice a day. You might like fabric pots of coco fiber, it’s a nice medium that filters the water from the fish and holds good water and nutrients and your bacteria component.
