I'm playing Agricraft in the Regrowth pack and I'm really enjoying it so far. I'd like to make one suggestion for a block: a devolver. When seeds are placed in it, they would be reset to stats 1/1/1. I hate throwing things away, and it would be very nice to "restack" all the old seeds I want to save for other uses (Botania, for example).
You should be putting them into the compost bin in Regrowth until you get all 10's anyway.
