Hello recently i have started growing a few mexican pings from the ones that grow on gypsum and limstone rock. Now they are growing well for me with the rain and ac water i collect for them. The tap water were i live have a high calcium content wich i cant use watering my Cps. I was wondering and i guss it would do no harm to the mexican pings if i water them with my tap water and that way save the rain water for my other Cps. Any body uses tap water for them?
What do you think?
