I had a all in one bag that stalled out but had a nugget in it so I cut open an Uncle Bens, dropped it in, and sealed it with tape. It was slow but it colonized the whole bag. Spread that in the bottom of that bin and ladled the "manure" part of the same bag on top and off it went.
Did Ecudor and Hawaian all in one bags ( 7cc ) and dosed UB's with with the left overs.
