Excellent find Bradley! Cost effective and easy to get as well.
My only concern is that I bet it would 'wick' up moisture much more so than excelsior. Just add more water, would prolly be a quick fix.
It stays pretty moist. You'll get your 30 days plus out of a culture...
It doesn't dry up fast, and I use Josh's...
