Ok, I have spider mites going after my grow room. So far I am sure that they have attacked all of the plants. Yesterday I sprayed the plants with no tolerance %50 diluted. Today I dropped 1000 lady bugs in the room as I would like to stay away from chemicals. The room is 20' by 5' total. They are all in veg stage and I do not want to get rid of my entire crop as a new batch of clones or seeds are expensive. For those with experience with these evil little creaters do I need to go as far as to add a bomb, or is the method I am going with enough? Yes I am sure they are spider mites.
