If you sell in any manner, legal or no, labor has to factor in there somewhere. So at $40/hr, over a 60 day period (if I do a 60 day strain) an oz costs me $128 and change in labor alone. Before I get blasted for being a financial rapist, I came up with that $40/hr figure as that is $20 less than I bill my time out at the shop. In this economy, it's a wage that will allow you to live decently. How many of you want to live in bare subsistence? So......to make a PROFIT, you at least double your costs (Many retailers triple costs), which will put the rock bottom price of an ounce of my bud at $280.
******If anything I count the time spent in the grow room as money saved....otherwise I'd be out in a bar or snowmobiling or riding my Harley, etc, etc....going in the grow room is better then going to the movies with the ole' lady IMO.
