There should be a list of hermie safe plants on the bar over there under the Crab Care FAQ -------->
From what I understand, store bought plants often have fertilizers that aren't hermie friendly, but with 4 weeks of cycling they should be ready (Or so I've heard.)
Personally, I'm growing some wheat grass seeds I got from my Grandma this weekend in a small box shower caddie.
I'm also fairly certain that they shred them to bits. So if you do get plants, hermit safe ones that you aren't going to miss are a pretty fun thing for them.
