Will minerals and salts in my water hurt plants?
I never really thought about this before, but I've been looking on some European sites that say normal tap water has too many dissolved minerals and salts. As tap water evaporates from the terrerium, they leave these substances behind, which can harm plants. This makes sense to me, but I just wanted to get yall's opinions.
I really don't want to fool around with an RO unit. I guess I could use bottled water, but it's a pain to have to run to the store and buy it all the time. Same with rainwater...too much hassle. Any ideas?
