The green smell disappears with curing. The longer they cure, the more the chlorophyll breaks down, the better they taste and smell. It's hard (unless you grow a lot) to wait a month or two for a good cure -- but I've had pot I thought sucked and put it away and smoked the better plant, and when I finally broke into plant 2 (2 months later) it had cured into awesomely good bud. I never would have guessed it was the same plant.

Also, use oroganic ferts and flush your plants with water the last week or so to create a less harsh smoke
