Well dilema, I say Wait as long as possible but in the next 2-3 days since you must cut them. Can you keep them under lights while drying them (Or rather have lights under them facing UP so that they use as much of their remaining chloraphyl as possible. I believe It is the Chloraphyl that makes the smoke HARSH so make it use as much as possible. That and Nutes thats why people reccomend flushing.
