does hay smell bad to you?! how did you harvest it? have you cut individual branches and hang them? did you do any trimming before ( this usually helps)
I hang them in a place where there's air circulation while on branches for around 7 days, after 7 days I cut individual buds and leave them for another 7 days; after around 2 weeks they go in the jar for curing for at least 4 weeks and then they are ready!
