| Well, I think all my problems may be due to the hydrophobic extract. I am wondering if it has a shelf life/temp sensitivity/other weakness that results in a degradation similar to the problem mentioned by Arlene with storing the mixed solution. I have a 1000 plants and I absolutely can't handle the 'occasional' failure of the product and resulting damage. With this many plants, the damage adds up fast. For mites, I am now using the Bayer Advanced 3 in 1. Seems to work well, without any damage, but it will probably not be until next spring before I know how really effective this stuff is, as the mite problem with the cold weather seems to have abated. I know this is true outside, where the source of reinfection is coming from, but I would expect any mites inside the GH to be happily forging ahead, and I have not seen any since spraying with the B A 3 in 1. I have sort of sprayed twice (first spray missed a few usually uninfected plants, ran out of time, and second one was thorough), but am having trouble getting the product in Prescott, AZ. Am in talks with Lowe's about including this in their regular stock.
