I've always been under the impression that the pyrethrin molecule breaks down extremely quickly when exposed to intense light, making organic pyrethrin products safe to use late into flower, where on earth did you get buds that still had a py taste to them? I've seen various commercial ops use pyrethrins two days before harvest without real problems, could this be because they took shop vacs to their plants the next day, between spraying and harvest?
