RE: "Cannabis Hyperemesis Syndrome" (CHS) is actually Azadirachtin (neem) poisoning!
I hear you completely. I don't take a hard-line stance against fertilizing, or managing pests, but I value natural solutions far above chemical ones. Especially newly developed miracle cure products promising triple the yield. As for neem, the compound itself is natural, but maybe it isn't natural for concentrated solutions of it to be dumped into the soil of cannabis plants. Which is what we're often doing to treat bug and larva infestations. Maybe further research will show that spraying small amounts of azadirachtin on leaves, during veg stage only, and being careful not to allow any into the soil, is relatively safe. But as for me and my plants, we're going to avoid it altogether for the time being. Surely there's something else on this planet that's both effective AND totally safe when taken internally! One of the safest things I can think of is cannabis, ironically! Maybe we will develop some kind of pesticide out of cannabinoids? Wouldn't that be amazing and fitting?
