I did! Transportation only accounted for 22% of the cost of a head of lettuce in my local Walmart, which wasn't really enough margin to justify the cost of the artifical lighting necessary to grow in Canada (even in dense southeastern Ontario). I think right now the most realistic application of these technologies is for premium products that are branded as such, like hot house tomatoes or living plants that can command 2-5x the standard barebones import price. Do you have different data?
