This is the ultimate sustainable homestead and prepper greenhouse, but purposely doesn’t look like it.Imagine a greenhouse that heats your home in the winter; and heats your water; that grows five times more food per sq. ft. than a hoop house; that provides food for you and your family all year long; where your food grows in 3 dimensions; where you never have to use fertilizer; where you never have to use pesticide, and where you can grow exotic foods (i.e. citrus or coffee trees in New England); that allows you to start seedlings in the spring; that hides your solar electric system; and that can house your small animals or incubate chickens and ducks. All disguised to look like a porch on your home, so that desperate and hungry passersby would have no idea that you have food growing there. This greenhouse does all that.This book is a simple, straight-forward, step by step approach to creating your own Secret Greenhouse of Survival, and it’s easy and cheap to build!Written by Rick Austin, the Survivalist Gardener, the author of the #1 Best Selling book in Garden Design- The Secret Garden of Survival- How to Grow a Camouflaged Food Forest.
