It has been a busy few months and we have some great news! We purchased a green house kit from a company called Clear Span, a manufacturer of fabric structures and greenhouses out of Iowa. It arrived at Arcosanti on 11/02/09.
This 20′ wide x 48′ long greenhouse, more specifically called a “High Tunnel,” is an unheated, plastic-covered structure that provides an intermediate level of environmental protection and control compared to open field conditions and heated greenhouses.
We have been putting together a presentation of greenhouse systems research to educate ourselves, the crew and the Workshop participants.
We are excited to begin the process of growing food and experiencing the life of a greenhouse closer to the “center of town”. We plan to use this greenhouse as a prototype for heat collection as it will be connected to the existing and in construction portion of the Heat Duct Tunnel and we will use rainwater collected from the building above for watering the crops. As a prototype, this greenhouse will help us perfect the design for the energy apron.
