I know it's way too late but in case anyone else comes here looking for answers; I don't know if this would work but I'm thinking maybe some dry ice in water? it should create a high CO2 level and a anoxic atmosphere for the mites and possibly kill them. Also, if anyone experiments with this idea, remeber not to leave the dry ice in there too long as temps are going to drop and you will kill the mites and freeze your plants too.
32yrslater Reviewed by 32yrslater on . Spider mites getting aggressive at 5th week flowering Hi there, What to do if you find a lot of spider mites and their eggs around 5th week of flowering? I have the impression that it is now way too late to stop them from spreading everywhere, but fortunately most of the upper buds are still intact. Should It be harvested right away? I know it's not entirely ready but there are quite a few trichomes already. Nothing amber tho, mostly clear/white. (see pic) I'm just thinking perhaps it would be better to harvest what is possible to save right Rating: 5
