Well....if they are hydrated then I don't see the worry.....? When I give food offerings I spray the pile wet...so they are getting the added water....
The babies are use to the wet greens and I have peace of mind they are well hydrated....I have also noticed (because I have done water sprayed and not) that they finish their pipe much more readily when it is sprayed than when not....
The advantage of wet greens is that they stick together and picky torts can't pick out the bits they like. I always rinse before serving; they take longer to shrivel that way
