I found a spider mite on two different leaves of a CSM clone this morning. I chopped it immediately, of course, and sprayed it with Raid. One mite is an anomaly, two is an infestation.
It was on the shop floor while everything else is sitting on tables. I'll wait a few days and see if anything else is infested. If there's any on the other plants, they are all going in the trash. No way I'm going to Germany for two weeks with infested plants in the shop, and no chance I'm going to stick one in the flower tent to flip.
The MXTLs are in the other room, so hopefully they will be immune either way. I can flower them in there, so even if they do get mites I will probably try to keep them to harvest. It will sure change my plans for everything else, though.
Since nothing in there is flowering, I'm going to hang a couple of pest strips while I'm gone. Those things worked well last year.
