Hi DGC, Love watching your show and have learned a lot. I started smoking in 1971. I’ve always wanted to grow but was too afraid of the possible negative consequences until it became legal in California.

Question: I had a bad infestation with fungus gnats. At the advice of a hydroponics store employee I used a soil drench using a product containing Spinosad. My fungus gnats were gone in a few weeks and have not returned. What is the down side of using this as a soil drench?
