Testing the Growbot Explorer went well. Fruiting for the Yellow, Pink and Blue Oyster mushrooms took less than a week for most testers. Subsequent rushes (aka harvests) were also successful.

Design changes for the Bubbler should ensure an output of greater than one pound per month per growbot, although this is dependent on variety. In addition, the "Bubbler" is big enough to support different carriers for mushroom substrate, including other bottle sizes, mycelium blocks (used by most grow kits), and small trays.
