>>928265Pretty much, yes. Each type has optimal conditions and requirements. You do lots of sterilization between working with different cultures.
It's like growing plants, but without the pests and the upkeep is *mostly* topping off the water and adding more algae food. There's no fussing like "is it going to freeze tonight? is it going to rain? spider mites? something is digging up my plants."
I enjoy it. If people think it's silly, that's OK.
