Features and installation of the greenhouse Shell
Content
pros
A polycarbonate greenhouse, and this material is most often used, takes up a minimum of space in the garden, while performing all the functions of a stationary greenhouse. The structure has a minimum of joints and cracks into which unwanted moisture or insects can seep, and besides, it is quite easy to assemble it with your own hands. The price range refers a polycarbonate greenhouse to budget buildings, and the overall strength of the polycarbonate frame makes it a profitable and durable purchase. The weight of such a greenhouse rarely exceeds 3-4 kg, so that it can be easily moved around the site.
Free access to plants inside the greenhouse makes watering and weeding them much easier. At the same time, you can independently regulate whether the sunlight will fall on the plants or not, simply by opening or closing the section. In addition, it serves as a protection against strong wind or rain and hail, which can harm the plants. And in the summer heat, it will make it possible to ventilate the plants simply by opening one or both sections.
And, finally, the shape in the form of a shell (or breadbasket, whichever is closer to whom) allows you to open both doors at any angle.
Minuses
Like any small structure that is not fixed in the foundation, a polycarbonate greenhouse can leave its “habitat” under a gust of strong wind. Therefore, it is necessary to further secure it. In addition, the frame is usually sold assembled, so a car with a large trunk is needed for transportation. However, if you have drawings and you intend to assemble a polycarbonate greenhouse with your own hands, then there will be no problems.
Unfortunately, even such a convenient design is not airtight, which means that rainwater, insects, plant debris can still get inside. In addition, the structure retains heat poorly inside and is completely unsuitable for growing plants in winter outdoors. That is, this is a purely summer-spring version of a greenhouse.

How to make
In order to make and install the structure, you will need blueprints, a sunny place and a little DIY work. Try to orient the opening sides to the north and south so that the plants get maximum sunlight during the day.
It is best to build a foundation for the structure, for example, a wooden box, pre-treated with fungicides. Dig a hole about 45-55 cm deep, about the width of a frame. Install the box (if using one). Pour a layer of sand 5-7 cm high into it, plant residues (leaves, tops, cut grass) on top, put fresh manure and fertile soil in the next layer. Fasten the frame (in the box if using it) in the ground, tamp it tightly. Now you can start covering the frame with polycarbonate.
Remember that it is better not to drill the sheets, but to fix them with mounting tape. At this stage, it is very important to prevent the formation of cracks in the moving parts of the structure so that water, fallen leaves, and insects do not get into it.
