When you’re considering building a garden greenhouse or polytunnel, you need to consider the features, cost, and ventilation of each structure before making your final decision. Here, we’ll take a look at some of the main differences between each structure and weigh up the pros and cons of each to help you decide which is right for you.
There are several ways to improve ventilation in a polytunnel, including doors on one or both ends. These doors allow better temperature control and cost very little to install. One alternative is to place water on the floor of the tunnel, which cools the air without moving any parts.
One of the most common problems with polytunnels is condensation. Proper ventilation is key to a thriving polytunnel garden. Using doors allows a through breeze, which aids natural ventilation. If you live in a place that receives high summer temperatures, you may want to use double doors or a larger sliding door to increase airflow through the polytunnel. Planting in shady areas can also funnel summer breezes through the polytunnel.
Price of a greenhouse
The price of a greenhouse can vary widely. It will also depend on the type of crops you are growing, as some crops need a reinforced structure, while others require special equipment to ensure that they grow well. The cost of a greenhouse also depends on the technology used to create it. Different greenhouses may have various systems and equipment installed in them, including ventilation, heating and cooling systems, air fogging, irrigation, hydroponic systems, artificial lighting, carbon dioxide supply, and more.
The materials used to build a greenhouse will also impact the cost. If you are building a permanent greenhouse, you will need to install a concrete slab and create a foundation. These costs can easily add up, as you can expect to pay around $25 to $35 per square foot.
