I understand them completely and use to grow that way and had much sucsess. I changed. I have a deep knowledge in botany ,chemistry and biology. Ive been growing for 20 years.of course ive eatin chem tomatoes and they taste like garbage . thats why i grown most of my own tomatoes and other veggies. I started to grow organic because i truly believe in the health and medicinal benifits of cannibis. Organinc food is prized for its superior flavor and superior health benifits . cannibis is no different. I avoid all inorganics in growing because i have some cancer patients and many truly sick people i help. I also have many people who came to me because they wanted off prescription drugs, so .I try to give them the most healthy clean product possible. If you you use inorganic foliar feeds or worse sestimic poisons or spray poision pest control ,when you make concentrates or eddibles these compounds are present in the concentrates or eddibles. I personaly preffer to educate my patients and give them the healthiest product possible since they and myself believe in medicinal cannabis. There are many people who are profiteers who choose cheaper chemical nutrients because of the ease and even worse PRGS and sestimic poisions because they dont care about there patients, they care about profit just like big pharmacy. Im disgusted by this kind of behavior it is taking advantage of people who are seeking cure through cannabis .I choose what i choose because of passion and humanity not because i dont understand something.you choose inorganic thats fine. I will alway choose organic and will always educate. Happy farming
