I have just been flushing these girls the last two weeks. the predator mites turned out to die the first time and the second time iv seen reduction but still have a mite issue. about to start chopping in 2 days and ill have it up to dry for the next week. the heads are so fat they aren't able to hold their own weight anymore and i haven't had time to go get yo-yos to hold them up. A few more days then chop trim dry and toke.
if not so much time left, and no younger plants there, maybe dont care with spidermites, and after harvest push the area with ozone. for me only that worked to completelly remove them from room.
