If you already have mites this is not the product for you. I kept my plants, outdoors, 20+ in 100 gallon smart pots, mite free in Northern California using this from planting to 4 week before harvest. I am a FIRM believer in this product if used before you have issues. If you already have mites I feel for you, as I've been blessed to not have dealt with them.I've used it half a dozen times and also the systemic 209 in the water. I don't understand how everyone else has had good results. 3 days after any spray mites are back full force. I mean I douse the whole friggin plants, container and soil as well as the walls and floor with horrible results. If the plants were past week 5 in bud when sprayed then no matter how much I washed them off the end product was not smokeable.To keep using this stuff to control the mites it would cost more than nutrients and dirt and electricity combined.
But this is just my experience. The systemic stuff claims to ward off thrips also, which I also don't find to be the case.
