hi jimbo i found spider mites last friday, i went to a local grow shop and they suggested predators i pick them up on thursday this week, they tell me that the predators eat all mites and eggs and it should only take about a week to totally clear.
the predators breed and move faster than the mites and once the mites have all gone the predators then just die off from starvation so maybe this is an option for you if you dont want your plants covered in chemicals. good luck
What kind of predators. Some of them like persimilis require specific conditions to survive.
