Very interesting responses to the question. Actual numbers? The real answer is no one knows. There are simply too many factors throughout the cycle.
It's like asking "I drive a Toyota. How much gas should I expect to buy in the next year." Who the heck knows? How many miles are you going to drive? Is it city or highway driving? Are the tires properly inflated...and the list goes on.
I think if I took ten of my anonymous customers and have them grow the exact same strain and then compare the results, you'd find that there were ten different amounts.
Finally, what's market value? I'm sure it would go for less in, let's say, Corpus Christi than in Northern Canada.
My direct answer to your question is anything from nothing (plant died or was male) to thousands of dollars.
(Oh, if there were a contest my plant would be the healthiest, hands down. I'd win!)
