insecticidal soap

[VickiC]

Hi Joann,
I think I've got the good-circulation covered...several fans, etc......but it's the humidity I really have to work at keeping up. For example, About 8:30 or 9 this morn. I went outside to my greenhouse and turned the swamp cooler on before I left to run errands...about 10:30 or so. When I returned about 3 hrs. later, the gh temp. was 96 and the humidity was 28%! I quickly opened vents hosed the floor and turned misters on, but it seems like everytime the exaust fan runs, there goes some of my humidity. It's a vicious cycle. Guess that's pretty much par for the course ?? Anyway, if it keeps this up, I might have to spend the whole day hosing the floor.
Thanks again for your help,
Vicki

I was referring to comments by gardeners about soaps, not the company advertising. Dishwashing liquid (see ingredients and MSDS) is often thought of as a cheap alternative to commercial insecticidal soaps. However, dishwashing liquids are less plant (and soil) friendly and are best avoided, regardless of the cost savings
