Since people have expressed concerns about pesticide buildup in a growth
chamber, you might want to consider Safers. It is essentially one of the
formulas for Ivory soap and it breaks up the cohesion of water molecules
so the insects drown due to water entering their spiracles. One cannot
just buy Ivory soap and make their own, however, because all but one of
the formulas is toxic to the plants. We bought ours through our local
nursery (they ordered it for us).
