Pricing the medicine

It seems like a good time to start a new thread since the "Tips for Growing" thread has introduced the concept of pricing. So, here we go. What's the cost of growing medicine? What's a fair price for patients? Should there be a sliding scale for patients based on ability to pay? Should caregiver operations be "non-profit" as is required in Oregon and by the new proposed California regulations? What does non-profit mean?

Have at it, folks, and thanks again for your participation
