Hello All!

Just got my setup today; 5-gal 8 bags.
Been searching a lurking here but can't find anything specifically about the RIGHT was to do this with dry material. Everyone is talking about fresh frozen stuff. Should I like re-hydrate this and freeze it before I throw it in the bags? Just rehydrate it? Does it matter at all; can I just toss the dry stuff in and start mixing? Also, I see some info about gram weight of fresh/frozen material to use in a 5 gallon setup but nothing about how that might equate to this dried stuff. It's a little powdery I'm afraid it might just clog up the screen in the bottom of the first bag and I'm not going to find anything further down.

Advice?
Thanks!
