Consider registering these items as usable in the bioreactor:

• Glowshrooms
• Berries
• Barley
• Potash apples

Saplings seem to be done already - perhaps automatically by MFR?
Also I haven't tested if glowshrooms can be planted or harvested, or if berries and barley can be harvested.

Ping @samrg472 - We take PRs for MFR but don't really support it directly.

should work in latest release
