A Seed Bag is an item in IndustrialCraft 2's Cross Breeding. It is sometimes dropped when harvesting a fully matured plant grown on a Crop. The Seed Bag contains a seed of the plant harvested, and it can only be replanted on a Crop.
A Cropnalyzer is required to find out the Growth, Gain and Resistance of the seed. If you have discovered a new Seed Bag, placing it in a Cropnalyzer will replace "Unknown" with the seeds proper name.
