High Sean,
You should use NEEM OIL this is a fantastic way for organic cannabis growers to get a pest and fungus-free garden. AND IT IS REALLY CHEAP!!!
What makes neem so unique is that it’s 100% natural and safe to use. It’s non-toxic to both humans and animals, and there are no negative effects on plants if you use neem oil properly.
I have been killing all types of bugs with it. When you want to get rid if bugs on the leaves simply spray the leaves with a neem oil solution and the bugs are death within a week. When you want to kill bugs that live inside your soil just simply water the plant with neem oil solution and the bugs will be death within a week.
I will send you a link form WayofLeaf where they explain everything about neem oil and how to use neem oil.
