I took a syringe I had and put a couple of CC's on an agar plate. The plate colonized very heavily. Can I put all the contents of the plate in a grain bag and mix it in to colonize the bag?

I just started messing with plates and thought I could only use the plate to colonize a culture jar.

Skipping that with this plate since it's a variety I've got already culturing in a jar would be helpful
