A shorter hoop house has the advantage of retaining warmth more effectively but could limit the growth of taller plants. It’s essential to consider the types of plants intended for the garden bed and their potential size when determining the optimal height.

Selecting the Right Plastic Sheeting

An essential component of a hoop house is the plastic sheeting that covers and protects the plants. There are numerous options available, and selecting the right one is crucial for the success of the hoop house. Some key factors to consider when choosing the plastic sheeting are:

• Durability: Ensure the sheeting is strong enough to withstand different weather conditions and prolonged exposure to sunlight. UV-stabilized polyethylene greenhouse film is a common choice for its durability and long life span.
• Transparency: Select a sheeting with good light transmission properties to allow sufficient sunlight for plant growth while providing protection from harsh weather and pests.
• Thickness: The thickness of the sheeting can impact the overall insulation and durability of the hoop house. Thicker options may provide better insulation but can potentially reduce light transmission. Common options range from 4 to 6 mils in thickness.

By taking these factors into account, one is better equipped to choose the appropriate plastic sheeting for their hoop house. With a well-designed hoop house in place, a raised garden bed can enjoy extended growing seasons and enhanced protection from pests and unfavorable environmental conditions.

Building the Hoop House

Constructing the Hoops

To construct the hoops for the hoop house, you’ll need PVC pipes. Measure the width of your raised bed and cut 1/2 inch PVC pipes into two pieces, each equal to the width of the bed interior. Bend the pipes into a hoop shape. Ensure that the hoops are of appropriate size to cover your garden bed and maintain structural integrity.

Attaching the Hoops to the Raised Bed

After constructing the hoops, it is time to attach them to your raised bed. You will need pipe clamps and a drill for this step. Follow these steps:

1. Measure and mark the spots on the raised bed’s sides where you’ll place the hoops. It is essential to space them evenly for better support.
2. Using a drill, create holes on the marks to install the pipe clamps.
3. Securely fasten the clamps to the raised bed, ensuring they are firmly in place.
4. Slide the PVC hoops into the clamps, and tighten them to hold the hoops in place. Make sure the hoops are evenly spaced and level.

Securing the Plastic Sheeting

To cover the hoop house, you will need a durable plastic sheeting material such as greenhouse polyethylene or UV-resistant polythene. Here’s how you can secure the plastic sheeting:

1. Unroll the plastic sheeting over the hoops making sure it covers the whole structure, with extra length on each end.
2. Secure the plastic to the hoops using clips or Velcro straps. Ensure it is tight enough to prevent sagging and loose enough to allow for expansion due to temperature changes.
3. At the ends of the hoop house, gather the excess plastic and secure it with ropes, bungee cords, or zip ties.
4. If desired, you can also create a ventilation system by leaving a small opening on one end or by using roll-up sides.

By following these steps, you’ll create a hoop house that effectively protects your raised garden bed from adverse weather conditions and extends the growing season.
