Me and my husband only grow indoors yet we constantly get spider mites. We've thrown out and cleaned everything more than once. We have been giving it another try and we BACK AT IT AGAIN with the damn spider mites. He's giving up and I have no idea what I'm doing. Send help
Aside from scrubbing the shit out of the tent and all tools and buckets I'll share what I did to end the sob from coming back. After I was done I sprayed and scrubbed with bleach. I made a rule to never bring cuts from outside back inside. My clones are now made from mother's inside and brought out.
Regardless if they need it or not. Prior to flower, at least once every few weeks they get a foliar spray of a water mix with a little peroxide, and neem and a few drops of blue dawn dish soap. I'll saturate the bottom and top of the whole plant. I do this in low light or dark. It's been years since I have had spider mites or any other critters like thrips.
I even added mosquitoe bits to the soil to stop fungus gnats. I reammend my soil so that's when I add the bits, plus DE and the other ammendments. Seems to be working.
