The Retractable Roof Production System from Cravo allows growers in warm climates to uniquely utilize the benefits of the natural outdoor environment and the protection of a controlled greenhouse environment to lower input costs while extending harvest seasons. The new system will help realize the higher prices of the shoulder seasons and extend supply season to distributors, increase yields which reduces the fixed costs per case, eliminate supply disruptions due to erratic weather so growers never lose a customer, grow organically or chemical free in order to achieve higher revenues and lower production costs and increase shelf life.
