USDA's High Tunnel 100% grant for Organic Growers has been extended through the 2011 year. I have been given this information directly by my NRCS agent and will be providing helping anyone who would like to apply. If you would like all the info, I can send you an email with your direct NRCS agent that will help you with the 3 page application (super easy) and the tunnels that are available. Just give me your State and County so I can search it for you thru the USDA site...or just provide it in this thread.
Typical sizes are 2250 sq feet 30x72 Premium High Tunnels which include everything to start growing.
Please contact me for any questions or If you want the complete email package my email is
