Building And Using A Hoophouse – Growing Beyond Warm Weather

How to extend your growing season with a Hoophouse.

When the weather turns cold, many gardeners think it’s time to pack it in until warm weather returns.

Although its true that a hard frost or freeze can stop vegetable plants in their tracks, a hoophouse can protect plants and extend the growing season well beyond traditional norms.

That means fresh vegetables earlier in the spring – and well into the first snowflakes of winter.

A large or even mini-hoophouse is a great way to extend the growing season.

In fact, some use these mini-greenhouses to grow all winter long. They are perfect for cool weather crops during the coldest months.

And what home gardener wouldn’t love a fresh salad in the middle of winter!

What Is A Hoophouse

A hoophouse is a greenhouse that uses plastic sheeting in place of glass to trap and hold heat.

The frame is made up of a series of hoops created from either plastic, metal or wood. This type of skeletal framing is inexpensive to create, and easy to set up and take down.

Hoophouses can have their frames constructed of plastic, metal, or even wood.

The hoops are anchored to the ground, or in some cases, to raised beds. They are then covered with a layer of clear plastic sheeting clipped into place.

The plastic covering works by absorbing the sun’s rays during the day to heat the interior. It then traps the warmer air inside during cool nights allowing plants to continue growing.

Additional protection…

In addition to thermal protection, a hoophouse provides additional protection to plants as well.

The plastic covering aids in retaining moisture, requiring gardeners to save on watering chores. They also protect crops from damage due to high winds and heavy rain. And if that wasn’t enough, the covered mini-greenhouse can also be a big help in keeping away insects and pests from stealing a harvest.

That can actually be a big plus in the early spring or late fall. It’s a time when many animals are searching for any food source, and fresh vegetables are an easy target!

Installing A Hoophouse

One of the best things about a hoophouse is they can be inexpensive to purchase as a kit, and even cheaper for those willing and able to build their own.
