The need to extend the growing season on a small scale or if you are supplying restaurants could be very important to you.  Cold Frame Kits are easily accessible online or at your local greenhouse supply location.  The cooperative extension of your university might have a building design guide for you to use as well.  For example, Purdue University and Minnesota USDA both have great guides available.  Once you have the cold frame built, you will need an irrigation system for your plants.  You can add a timer to turn it on and off as well as manual valves.  The most important part is the drip irrigation.  A quality system to deliver the water will help give you the production you are looking for.  We offer some pre-packaged drip irrigation kits that will deliver the water needed.  Individual parts are also available to customize your system in the future.
