@Vapo69 . I get a little algae on the smart pots in the greenhouse, never seems to bother. Same algae grows on the top of the soil in the garden. Never gets slimy on the pots though
material type pots do seem to take on a life of their own.have seen white crusty ones to.
Aaaaaaaahhhhhhhhhhhhh..............that's betterthey grow algae, white soil mold of the type I see around the compost, and they accumulate crust from mineral deposits
