But the same idea applies there; why would I grow marijuana indoors? I genuinely don't understand the benefit; to my knowledge, outside of them being higher CO2 output, higher real estate cost, and substantially higher energy usage, none of these indoor facilities even reach the calorie density of a modern hydroponic greenhouse like Houwelings; http://www.houwelings.com/ http://www.houwelings.com/ I guess I should say: Hats off to the people that think they can compete with a modern ag operation like Houwelings in growing weed, if they can do that while paying both urban real estate rates and the electricity bill for replacing the sun they know something I don't.
