i think the concenus is to use Neem Oil, it's organic and safe for the plants and humans. I just bought a bottle at Home Depot because i just found some spider mites on my clones. You dilute a teaspoon or two to a gallon of water, spray the entire plant with your main lights off, fans too to keep over spray to a minimum. Spray the bottom side of all leaves! Also spray the top leaves and carefully spray the buds. I let my spray set up a bit then gave the plant/branches a good shaking to knock off most of the excess water and hopefully some mites. I've sprayed mine twice now and with any luck the critters will be gone by tomorrow. good luck, I nearly shit my pants when I saw the mites and I can't wait til those suckers are long gone. I was surprised I got the mites, I harvested my main crop almost two weeks ago and didn't notice anything funky so it looks like this happened very recently. Good luck, hope it works for you too!
