I'm currently thinking about the topic of microplastics in hydroponics. In this context, I came up with the idea of using Gastronorm containers for the Kratky method. There are also Gastronorm containers that are perforated. That might be a good replacement for mesh pots. Do you think stainless steel would be a suitable material for hydroponics?

Roots need larger holes
I wonder if ceramic wouldn’t be a better idea. I don’t know how feasible that would be, but I’ve definitely seen stainless steel rust before.
Will anything leech from the metal into the soil?
Stainless steel does rust eventually and considering you’ll be adding fertilizer that could potentially cause deterioration in the metal over time.
