I have plants at different stages in their life cycle. I have done a decent job of keeping pests away. Cinnamon is what I use to keep ants away. The following day after a rain, the cinnamon is washed a away. I notice that about 4 weeks before harvest, right before I apply the next dose of cinnamon, I find 1 or 2 ants that have crawled up to the colas and have overdosed on THC trichomes. I laugh out loud every time I see that.
