It's also good just to keep it on hand in case you have a problem....not something you NEED to do....I like doing it and I like the little grow kick my plants get from it.

I like to have a couple of bottles sitting right up in the room where the plants can see them. Those bottles are Fox Farm Bug Spray, Serenade, and h202. I think having them around helps keep some of the monkeys in the cages.....
