premature seed need to save

hey I have a premature seed form a batch of really good stuff it's hard and slightly brown more greenish what it the best what to finish this off and save it to use. its fresh stuff is there a way to air dry it if so how long should I let it set befor using.

like I know with normal seeds done fresh out of the bud you should still wait what is normal for those.

if it's truly premature, there is really no preparation you can do that will make it mature and be viable.
