If your forced to grow it inside a building, under artificial lighting, with heavy security and heavy regulation; then yes it's ~15$ / oz (225 per pound). Cut out that crap and use a field and it's far cheaper.

PS: I don't smoke and have no idea if 'hydroponic' is better for the plant or if it's a proxy for grown in the US and fresh. But, I suspect it's mostly about post processing.

Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil.[1]
