doesn't matter how good ur bud is when its cut it will always smell like grass! lol put it in a mason jar and give it at least 3 or 4 weeks, opening the lid for a few hours each day. Try a bit after 3 weeks an i guarantee it'll be the best smellin pot ever! It's just the way it is, i was so shocked first time i grew, had some awesome buds but after dryin jus smelt like grass, after a month of curing it was the nicest smelling/tasting weed i'd ever put my hands on, just needs time dude, be patient!
