If you need to find a way to extend your growing season due to the climate in which you live then you should consider high tunnel greenhouses as a viable option.

They are called high tunnel greenhouses because quite simply they have high ceilings.

• They are made from a clear plastic which keeps the heat of the sun on the inside where the moisture is controlled.
• Because of the material and the way they are constructed they do not require much space and are therefore suitable to the person who has limited outdoor space available to them but still wants to be able to have a greenhouse.
• Learning what is a green house, what types of greenhouses there are, and how do they work, is a critical part of any greenhouse gardeners game plan.

Benefits of high tunnel greenhouse structures:

1. By keeping your plants separate from the exterior environment they are better protected against diseases and insects.
2. Because the water is collected inside the tunnel the interior climate is kept under control.  These are just two of the many benefits of a high tunnel greenhouse, compared to portable greenhouses saving space as their primary benefit.
3. When you experience seasons when there is too little or too much rain and fluctuations of temperature you also have the advantage of having control of the interior climate by being able to add thermostats, fans, automatic shutters or heaters.
4. In areas where the climate is generally colder this is especially advantageous if you want to yield plants that are stronger and better.
5. People interested in growing the more delicate vegetables such as lettuce will find this particularly beneficial.
6. Being that these are high tunnel greenhouses there is also the possibility for growing the creeping plants such as tomatoes.

When it comes to purchasing high tunnel greenhouses you will find that they retail at around $2000 but it is important to remember that the returns on the investment make it well worthwhile.

Instead of being restricted, by weather and climate and having to wait, for the right time of year to begin your planting you can have the advantage of getting an early start.

For people using the greenhouses to grow produce for sale, this is definitely a distinct advantage.  Because the sides are made from plastic it is easily replaced if necessary.  The plastic retails for around $200.

• Thanks to the benefits of a greenhouse you could produce multiple times more than you would without a greenhouse.
• All these points are what makes owning a greenhouse, whether a high tunnel greenhouse or one of a different style, such a pleasure.

High tunnel greenhouses can be found in a number of different styles including lean-to which require a pre-existing structure, straight-sided, and round, as well as in a number of different sizes to suit just about any need and space.

Some of the styles are portable and collapsible making them easy to transport and store. For anyone in the business of growing fresh organically grown fruits and vegetables owning a high tunnel greenhouse will definitely be a wise investment to make.

• However even the gardening enthusiast who enjoys gardening as a hobby would find these greenhouses indispensable.
• Not only can they expand the choice of plants they wish to grow but they can have the pleasure of their hobby any time of the year.
