I honestly don’t know much about over the counter stuff beyond Neem oil and SNS for organic pesticide. I try to be as close to 100% organic as is possible and try to make all my own stuff. Primarily because I want to build healthy and reusable soil so there’s something left for our children and grandchildren and so on. Also I got into 420 growing for health reasons and have making concentrates for medicine and didn’t trust anyone else to provide because commercially most meds are made with larf and sugar leaf rather than premium organic flower. When you’re trying to beat cancer you probably should try to avoid taking in pesticide, etc. So while I may promote organic and hope everyone eventually adopts it in the future, I try to avoid being a zealot and argue my case objectively without judgements against other methods. I learned a lot from being open to other ideas.
