Have you ever wondered if it could be done? Can you create a greenhouse that needs NO supplemental heating year round? the answer is yes!! This greenhouse design, involving stored water as thermal mass and our bountiful Colorado sun, can be used with recycled materials or new. You can apply this method to pre-existing greenhouses, attached or single units. Water is the most efficient thermal mass but there are many other options as well learn how to use them while recycling all kinds of materials. The Parmenters built their greenhouse out of 90% recycled materials and it sits on top of a decomposed granite mountain at 8,120 ft. This technique works at any altitude. Fresh, organic food year round in Colorado is a sure thing we have more than enough sun. There's always something to eat!
