i suggest that you make a separate space for drying. i placed the drying chamber above the flowering chamber just before the exhaust, so it gets vented along with the room. I hang them because it is the simplest way and it allows for maximum air exposure. laying them even on nets will cause the branches and leaves to lay over each other and delaying the dry. if you want to grow again right away, i don't think that using the same space is a good idea as in some more humid times they might take some time to dry, and the size of the buds matters too
