Hey everyone two days ago I had a somewhat major spider mite problem. They had already begun chewing the leaves and such, anyways I needed a cheap quick fix so I ran to home depot and picked up a concentrate bottle of ortho volck oil spray. It was less than 7 bucks. I went home to use it, sprayed the plants down and turned the lights on after 4 hours. Checked them out and all the spider mites I had then clustered to one area, I came back yesterday morning all of them dead and not a sign of mites anymore...Figured someone wouldnt mind this info for a cheap solution that works great
