Site owners prefer to grow vegetables rather than purchase them from the store. It is difficult to determine at first glance whether a product on the table is harmful or useful.

Therefore, providing oneself with both healthy and tasty food is within the power of every summer resident. A greenhouse is an excellent helper.

It helps to increase yields. To build, you need to spend not only effort, but also time, but such costs will pay off.

The choice of material for the greenhouse

When deciding on the choice of material for the construction of a greenhouse, it is necessary to pay attention to the products of well-known brands. For construction, it is best to use cellular polycarbonate of the required thickness.

It retains all the necessary qualities, is easy to install, perfectly transmits light, is flexible, allows you to do without a rigid frame, and also withstands dampness and temperature extremes well. One of the sides of the polycarbonate sheet must be covered with a special layer of UV protection.

Requires combined use of cellular and profiled polycarbonate

The difference between this material and others is that the condensate that appears on the inner side of the sheet is evenly distributed over the surface, forming a transparent film. It increases the illumination in the greenhouse.

Choosing a place for building a greenhouse

Before you start building a greenhouse, you should decide on its location. It is best to choose the most open area, away from trees. Avoid placing the greenhouse near tall buildings: in summer they will not interfere, but in winter, when the sun is low above the horizon, they can obscure the greenhouse.

Think over the location so that the amount of sun falling on it is maximum at any time of the year.

Installing a greenhouse facing east-west will allow you to start growing light-loving crops a few weeks earlier, thus saving energy for heating and lighting. A good warm-up will help prevent condensation from forming in the morning.

It is better if the place chosen for the greenhouse will be as even as possible. Such a landscape will allow watering plants without much difficulty. In the case of a slope of the site, leveling the site, you need to add earth.

It is impossible to ram the soil, as the plants will be deprived of a sufficient amount of oxygen. If the site has a slope and drip irrigation on it, then the lowest sector will be flooded with water.

When installing a greenhouse designed for regular maintenance, you should include a water supply, electricity and heating device in the estimate.

The next item is drawing up a project, that is, a drawing and an estimate of the consumption of materials. At the stage of drawing up the drawing, pay attention to ventilation. It is the cause of consequences such as disturbances in the pollination process and the appearance of pests.

Based on the area, you can calculate the heating of the greenhouse. If you have any difficulties with the calculation of materials, you should ask for help at the place of purchase, showing the consultants a drawing.

How to build a greenhouse with your own hands

A polycarbonate greenhouse foundation is required

It should be done so that the structure does not sink into the ground, in order to avoid the destruction of the building. The traditional strip foundation is quite enough, which can increase the reliability of the structure. Bookmarking it will require an application of labor and time, in addition to accuracy and thoughtfulness of actions.

If the site is located on peat soil, do not forget about the strapping to eliminate troubles in the future.

After determining the shape of the greenhouse (usually a rectangle of 3 * 6 m, up to 2.5 m high), the foundation should be poured along the perimeter of 3 * 6 m. Depth, width, padding and pouring are standard, you can reinforce the foundation to increase its strength. If the structure is reinforced, exceeding the standard dimensions, then reinforcement and the output of the ray to the outside is a prerequisite.

Further, a supporting frame is installed on the foundation. The material for its manufacture can be steel, aluminum or mounting profile.

For the construction of a winter greenhouse, both profiles and pipes are applicable. The metal profile is much cheaper, but such a structure may not withstand the load. Difficulties arise in the delivery of pipes and bending. The last problem is solved by using a pipe bender; you can rent it in a specialized store.

The metal corrodes. Therefore, for protection, you need to cover it with a primer and high-quality paint. During the operation of the greenhouse, attention should be paid to the slightest defects in the metal immediately, periodically touching it up. The best option in this case is galvanizing, which significantly increases the service life of such a frame.

The most common forms are "house" and "arch". A gable roof has no advantages over an arched roof, since with the advent of polycarbonate, the need to adhere to clear geometric shapes has disappeared.

It is better to install a more durable frame for reinsurance. Stiffening ribs fixed with self-tapping screws should be provided. In the frame, the presence of doors and a window opposite is required in order to ventilate the room in the future. To provide additional reliability for the entire structure, the steps in the crate should be minimal.

After the foundation and the completion of the frame, you can start covering the greenhouse. If you follow the process strictly according to the instructions, then it is simple, although laborious.

Polycarbonate profiles are used for work. The bottom ends are closed with a perforated tape that prevents dirt from appearing, and the top ends are closed with a solid aluminum tape. In arched greenhouses, both ends are closed with a perforated tape.

Consider the size of the polycarbonate before cutting it. This contributes to savings on costs and panel residues. Cutting can be carried out using a circular saw or jigsaw, after preliminary measurements.

After that, you need to mark the fasteners, drill the holes for installation. An electric drill is used in their manufacture. Distance from the edge - not less than 40 mm.

Next, the installation phase begins.

The greenhouse is assembled by fixing profiles and polycarbonate sheets to the frame. For this purpose, fasteners with seals, thermal washers, and their covers are used. Self-tapping screws should be slightly larger than the mounting holes.

After installing polycarbonate sheets and their parts, ensure tightness and thermal insulation. This is done using self-adhesive perforated tape.

With the help of a polycarbonate greenhouse, it is possible not only to grow many crops, but also to harvest crops even in cold weather, provided that the greenhouse itself is properly manufactured. Provided that all construction recommendations are followed, the greenhouse will be an ideal place for growing plants.
