Ric, good information. I have never actually used those "commercial" ones made for GH use. For all I know they have the same active ingredients as those sold for home use. Then again, the GH foggers may be much more potent and have a longer residual affect. I really don't know. Naturally, when you trigger the fogger in a home or in a (home) greenhouse, you quickly vacate that area and won't return for an hour or more. When I'm doing my fogging, I will do it in the AM, close the door, and not return to the GH until late afternoon or even the following day.
