The cost to grow a gram of marijuana in North America is between $1.50 and $2.35.
Very interesting. I'm guessing homegrown can be inexpensive or very expensive depending on the setup. For example, an outdoor grow can theoretically be free.
Looking back at the cost of a small hydroponic grow I once enjoyed, the startup cost was the big cost.
I had a modest 6-plant grow room costing around $1500-2000 at the time. From that I produced roughly 12 premium ounces every three months for about $300, maybe less.
If these figures are representative, then after 4 crops are harvested you would recover 48 ounces for a total cost of $3200, which is $2.38/g.
Of course it's a long term investment. The total cost of 8 crops, 96 ounces, would be around $4400 or $1.64/g.
After the equipment cost is paid out (or sunk), it should only cost around $300 for 12 ounces, which is $25/ounce, $0.89/g. These are probably outdated figures, but still in the ballpark hopefully.
A minor point but I would probably only grow 2 crops per year, I found that it works much better when you can easily keep the temperature below 70°, preferably around 68°, in the fall and winter. This stretches the payout out over a longer period of time. Really strong weed will stink up the entire neighborhood if you're not careful. HPS lights generate a lot of heat. I mixed HPS and LED.
No way I'm buying Chinese weed. It's an excellent hobby. I read about some Acapulco gold seeds in another thread.....
