I too was close to just giving up and saying the hell with it over those evil creatures. I cleaned and sterilized my flower and grow rooms several times between runs , and they still came back with devistating force.
What I did:
Temps - I installed a swamp cooler onto my flower room ( not enough available power for an ac ) and set my lights out temps for 70 deg. ( It actually goes down to the high 60's ) Mites do not like cold. Lights on temps are mid 70's to low 80's ) previous to doing this the temps would stay in the 80's and reach the lower 90's with lights on.
Avid is what I treat any plant with that goes into the flower room with.
ALTERNATE insecticides. I spray every weekend. As I mentioned above, I use AVID when they first go into the flower room, then I alternate on the following weekend with an organic spray ( Organicide), then on the next weekend I use a different spray, and on and on, swapping with different killers. The theory behind this is that the mites build a tolerance to using the same insecticide to the point of becoming completely imune. In effect you would be creating super mites that are immune to whatever single poison is being used.
Keep it clean, simple to say, harder to do. It must be a religion to an indoor grower.
Try to find strains that have an inherent ability to survive mite attacks like g13 and strains with g13 in it.
Filters on ALL incomming air, I treat the filters with mitacide as well.
Believe me when I say I've tryed everything there is and sticking to the above regime works very well for me. The turning point was when I got a handle on the high temps which spidies love. Bringing the lights off temps down low works very well to dicourage them. I even let the temps get down into the mid 60's every once in a while ( just like in nature ) and have noticed an improvement just from doing that. Also the healthier your plants are, the more damage they can fight off and the more they can recover from.
Good luck on your battle. I feel your pain.
