My spider mite problem I found had a lot to do with the high temperature that my HID fixtures were contributing to the room. About a year ago I switched my indoor grow to the 400 watt induction grow lights from the 1000 watt HPS mostly because of the heat and wattage. I've been very satisfied with the canopy penetration and yields from what had been 4 of the 1000 watt HPS to 3 of the 400 watt inda-gro lights. I don't know if they'll find a way back in but so far it seems they don't do well under the lower temperature lights.
