Building a hoop house is an excellent way to extend your growing season, especially in Zone 1, where the cold climate can limit gardening possibilities. A hoop house provides a protected environment that traps heat and shields plants from harsh weather conditions. This guide will walk you through the steps to construct a simple and effective hoop house suitable for Zone 1 gardeners.
Planning Your Hoop House
Before starting construction, consider the size and location of your hoop house. Choose a sunny, well-drained area that receives maximum sunlight during the day. Determine the dimensions based on your available space and gardening needs. A typical hoop house for small-scale gardening might be 10 to 20 feet long, 6 to 8 feet wide, and 6 to 8 feet high.
Gathering Materials
- Flexible metal or PVC pipes for the hoops
- UV-resistant plastic sheeting (6-8 mil thickness)
- Metal or wooden stakes for anchoring
- Zip ties or clips to secure plastic
- Door frame materials (wood or PVC)
- Tools: saw, drill, measuring tape, hammer
Constructing the Hoop Frame
Start by marking the location of your hoop house on the ground. Measure and cut the pipes to the desired length, typically 6-8 feet for the height. Bend the pipes into semi-circular arches, ensuring they are uniform. Secure the ends of each pipe into the ground using stakes or by burying the ends for stability. Space the hoops approximately 2 feet apart to provide adequate support for the plastic sheeting.
Adding the Covering
Drape the plastic sheeting over the hoop frame, ensuring it covers the entire structure with some excess at the base. Secure the plastic to the ground or frame using zip ties, clips, or weights. Make sure the plastic is tight and free of wrinkles to prevent flapping in the wind and to maximize insulation.
Creating Doors and Ventilation
Cut an opening on one side of the plastic to serve as a door. Reinforce the edges with additional plastic or framing materials. For ventilation, create small vents at the top or sides that can be opened and closed as needed. Proper airflow is essential to prevent excess humidity and maintain healthy plant growth.
Final Tips for Zone 1 Gardening
In Zone 1, winter protection is crucial. Consider adding additional insulation, such as bubble wrap or thermal blankets, during the coldest months. Use heaters or heat lamps cautiously to maintain optimal temperatures. Regularly monitor temperature and humidity levels to ensure a healthy environment for your plants.
Maintenance and Care
Check your hoop house regularly for tears in the plastic, loose supports, or drafts. Clear snow from the roof after storms to prevent collapse. Ventilate during the day to prevent overheating and close vents at night to retain heat. With proper maintenance, your hoop house can significantly extend your growing season in Zone 1.
