Today, there is an interesting twist in agriculture, where cannabis, being a premium crop, has what some claim to have significant medical and health value and is therefore a growing market for the commodity.
CO2 is increasingly being used for crop growth enhancement inside closed greenhouses; as well as applications in the fields, for growth enhancement.
