Instruction Manual for the QuickHoops Low Tunnel Bender – #7616 – 3'Wx4.5'H – The 3-foot bender model easily creates hoops ranging from 3 feet wide all the way up to 6 feet. These different configurations have a whole range of applications, from extending the growing season for cold-hardy crops with a very late season harvest or overwintering them for earliest possible spring harvest, and for different bed widths, to protecting delicate flowers and fruit from rain damage. Note that only the 3-foot configuration is suitable for shedding snow loads.

Recommendations from Johnny’s tomato research and trialing team.
Based on our extensive winter trials, this guide offers specific planting charts and guidelines for a successful winter harvest and overwintering program, with recommendations on what to plant and when to plant it.
Hoop loops are ideal for supporting one or multiple layers of row cover for low tunnels in protected culture. The loops twisted into each hoop allows for string to be stretched the entire length of the row without having to tie any knots, making installation and removal quicker. Each hoop is made of #6 galvanized steel. Johnny's offers 3 different hoop widths to accommodate varying bed widths. Follow these installation instructions for best results.
Follow this set of guidelines for optimizing your harvest, including tips and recommendations for year-round production and harvesting, an explanation of the details of carrot season extension by variety selection, succession planting carrots, early carrots, main harvest carrots, storage carrots, and carrot types such as Nantes, Imperator, Parisian, and Kuroda, from the carrot breeding and trialing team at Johnny's Selected Seeds.
Unroll and place directly over transplants or planted seeds for “floating” installation, or over #9 Support Wire, Hoop Loops, or Quick Hoops™ to create a low tunnel environment. To anchor, secure with Snap Clamps, Row Cover Hand Pegs, sand bags, or dig a furrow along each side and cover the fabric edges with soil. If your plants are insect-pollinated, it is advisable to remove insect barrier when plant blossoms open, to ensure adequate access by pollinating species. Remove row covers if temperature exceeds 90°F/32°F inside the row cover.
