The ATTRA Hoophouse for Crop Extension webinar (online web seminar) is now available online. You can watch it here: http://attra.ncat.org/video/. (Note that url may change as ATTRA adds additional videos to its collection.)
The hour-long video discusses the benefits and drawbacks of different types of tunnels, site selection, construction, cropping and more. If you are unsure you want to watch the entire presentation, you can view the PowerPoint slides in .pdf format first.
