It is the chlorophyll you smell and until it all converts it will smell like that. Stick in the jar closed for another week and see if it is better. Yes, you can throw them in boxes or bags in a single layer, lay them on shelves made of screened substance, use a collander, upside down is just a convenience thing, I cut all the buds off and lay them in a wire basket thing, one layer. Set until color turns, then to smaller basket with greater airflow for another week, then the jar for a week. Then I see what it needs, further drying or curing.
