Hay?
it should smell like cut grass
thats the smell of the chlorophyl, once it breaks down it will be fine, your buds are very GREEN, did you lay off the nitrogen a few weeks before you cut? this will reduce the amount of active chlorophyl [which is only needed most during veg]
your potency may have suffered slightly because of an inbalance i wont go into
any extra chloro your buds need, they will rape them from the leaves during the last weeks, [you can tell this when they turn yellow]
mkay?
dry it as slow as possible. make sure there is a lowered air exchange in the drying room, so they dont become dry within 3 days, or youll retain the hay smell there.
maybe give this 'newb' sum rep
