I make RSO/FECO mainly for people with cancer. I moved from California to Arizona and I'm having trouble sourcing material to extract. I've tried some local grow shops and pop-up events with limited success... I get some material, but not a consistent supply. The flower has to be grown organically... and there is one brand out here called Abundant Organics that has the quality flower I'm looking for. Is it feasible for me to contact them to start an account to purchase flower? Or, what is suggested in this situation?
