If we simply double it to include retrieval costs (it'll do for the sake or argument), and convert pounds to kilograms, then a kg of carrots at Woolies inflated prices of $1.88 looks pretty good compared to $22,000 for orbital carrots. And I haven't included the maintenance costs of the space farm either.
It makes sense that space stations and lunar bases should be as self-sufficient as possible, so we may yet see space farms of some sort, but not for Earthly consumption ... IMHO, of course.

I could say with the price of water.... and they're selling so called 'fresh air' in cans in China which is ridiculous
