Greenhouse "Harvest Classic" made of polycarbonate - a durable greenhouse for the northern regions

Despite the emergence of ever new, more advanced and modernized models, everyone’s favorite greenhouse “Urozhay” has not lost its position for several years now. This is a fairly durable and warm structure with an arched shape (“Harvest Elite”) or a “house” shape (Urozhai Classic greenhouse, the very first option). Its frame is made of galvanized steel pipe 25x25 mm and 0.9 mm thick. The height of the greenhouse is 2.2 m, the width is 2.5 m and any length that can be a multiple of 2 meters. The greenhouse has 2 windows and 2 doors at the ends, the distance between the arches is 1 meter. The covering for the greenhouses of the "Harvest" series is either polycarbonate or white agrotex - here it is optional. The frame of the Harvest greenhouse is made of galvanized metal, and cellular polycarbonate is used as a covering. The Harvest greenhouse can stand without a foundation, and if necessary, it can be easily moved from place to place, especially since even one person can lift it into the air.

One of the latest Harvest models is the Harvest Elite greenhouse. Its assembly is already much more difficult, but thanks to the improved design its strength has become much greater, which is especially important for the harsh Russian winter. But the Harvest Economy greenhouse is no less popular today - compact and inexpensive. There are two options - 1.5x1.8x4 m, with both doors at the ends, and 2x2x4 m with one door with a window and just a window at the opposite end.

Advantages of a greenhouse

The very first and main indicator is that the structure can withstand snowfalls of any intensity and even stormy winds, therefore it is recommended for use in the northern regions. In addition, the greenhouse:

1. Differs in multi-purpose purpose.
2. It has increased strength: engineering calculations for all loads far exceed GOST standards.
3. Installed by digging T-shaped ends into the ground. It is necessary to deepen to the bottom trim. You can remove the ends and install the structure on a foundation made of boards, timber, or metal corners.
4. Easy to assemble and transport.
5. Quite durable: service life - from 20 years.

The main purpose of a greenhouse is not just to create the most favorable microclimate for cultivating various crops, but also to provide the opportunity to carry out this process all year round. All that remains is to maintain the temperature required for the plants inside the structure.

How to make a good foundation for this greenhouse?

It is best to make a foundation for such a greenhouse - the galvanizing of a profile dug directly into the ground can simply come off, and the frame will simply begin to rust. So, experienced builders advise making the following foundation for this greenhouse: sand cushion + posts + timber. To do this, it is best to purchase ordinary concrete cubes in advance, 10 pieces - 4 pieces will be on one side and one at the ends. You will also need a sand machine. But it will only take a day to make the foundation.

So, you need to dig 10 holes 60 cm deep and 50x50 cm wide. Gradually, the holes need to be filled with sand and compacted well with your own weight. After which you can start laying the treated timber - it is best to order it from a store, 6 meters long, and have it processed there (but sawn in half will be worse in terms of the strength of the entire structure). The most important thing when laying timber is to place the entire perimeter in a perfectly horizontal plane, for which sand can be added under some cubes and removed from under others. And as soon as the building level shows the norm, the wooden foundation for the Harvest greenhouse can be considered ready.

All that remains is to seal the gaps that have arisen between the greenhouse and the resulting foundation. And this is not much, not little - 15 cm from the timber to the lower profile. And better material. Which is not afraid of either water or frost, like linoleum, in this regard, one cannot imagine.

Design Features

To produce the base for polycarbonate sheets, the manufacturer uses a galvanized closed pipe. Thanks to this, the frame is not subject to corrosion damage.

Note: Since the frame parts do not need painting, they do not harm the environmental situation inside the greenhouse: paint is a chemical substance, therefore, when heated in the sun, it can release toxins.

In addition, a closed pipe is a very durable material, so it is ideal for creating a frame for a greenhouse made of Harvest Classic polycarbonate. And if we add to this that the frame is made carefully, the holes are made very precisely and all the parts fit neatly, then it becomes clear why the base is strong and reliable.

"Harvest PCT"

Like the previously discussed models, the “Harvest PKT” is an arched greenhouse. The frame of the greenhouse is made of Larsen tongue and groove, which is a special Ω-shaped galvanized profile. Another feature of the model is that the gap between the trusses is 67 cm, which means that the number of arcs is greater and the strength of the structure is higher.

The four-meter greenhouse has 7 arcs. Thanks to these features, “Urozhay PKT” is considered one of the most load-resistant models in the “Urozhay” series.

Specifications

The basic model weighs 50 kg. When packaged (for this purpose it is placed in a box), the product has dimensions of 18.5×210×11 cm. If the product is purchased with an extension, then the dimensions of the latter are 11×9.5×210 cm and weighs 25 kg. At the same time, you can purchase not one extension, but several - to install a structure of the desired length. The height and width of the structure are fixed values ​​- 2.2 and 2.5 m. The greenhouse can be any length, starting from two meters.

The basic kit contains:

• fastening - 4x25 and 4x4 screws. But you can buy a kit with 4.2×25 and 4.2×16 screws. Galvanized washers are also sold with them. But, these fasteners are designed for polycarbonate with a thickness of 4 mm, so when choosing a material of a different thickness you need to pay attention to this;
• the basic package includes 2 doors and the same number of transoms, but if necessary, side windows can be purchased;
• polycarbonate 2.1x6 m - 2 sheets: one for the tunnel, the other for the ends. But this is for a basic two-meter model. For a four-meter greenhouse, for example, 3 sheets are needed.
