You grew it without any idea as to what the street value was? Go buy some. That should tell you right there. Buy an 1/8 and see what that costs you. And then do your own math. If they charge $50 for the 1/8 then assume a 1/4 will be $100 and most likely some kind of deal cut on the 1/2 and the full. Like 50/100/175/350. Its only worth what people will pay for it. Start at a number if nobody wants to pay that then its not worth it so drop the price.
