Advertisement So I'm getting an oh-so-desired P. metallica this friday. As far as I'm concerned they don't require any special care and have no difference from, let's say, P. regalis in terms of care conditions. Any PRO tips for this species? One other question - I've heard different versions for moisture in Pokie substrate. One place I see it's recommended to let it dry out completely and then flood it once 1 month. In another place I see it's better to keep it slightly moist, always etc etc. Someone care to enlighten me on this matter?
