Project: Heating and Ventilating System

Bob meets with HVAC contractor Dave Talbot to discuss the heating and cooling of the greenhouse. A system of thermostats, blowers, vented windows, and boiler has been designed to maintain ideal temperatures in the greenhouse.

Bob tours the Indiana Limestone factory with Dave Kern, who explains the fabrication process for the limestone columns being used in the greenhouse.

Bob checks on the progress of the greenhouse construction and examines the framing of the pergola roof.
