The yield of greenhouse crops largely depends on the location of the greenhouse. When choosing a place to build a greenhouse for polycarbonate, you should follow the viber data of agricultural technology. Lighting promotes plant growth and fruit ripening. You cannot install a greenhouse in the shady part of the garden, next to the house, or outbuildings. When attaching a structure to a house, you should pay attention to the movement of the sun. The best option would be a wall facing east-west.
Accumulation of water and frequent frosts make lowlands of garden plots unsuitable for the installation of clos-ground structures. Elevations with light loams look preferable. When installing a greenhouse on a slope, the surface is level. Installation of a wooden structure on clay soil, where moisture accumulates, will lead to rapid rotting and deformation of the frame. Heavy loams are improv by adding humus, compost, sand – a bucket per square meter – for autumn digging. The greenhouse is rais 20-30 cm above the how the b2b sales process has changed due to the foundation. Installing the structure far from the house is not justifi – watering and connecting the necessary communications are difficult.

Building material
The material for building the foundation is determin by the type of greenhouse and the condition of the soil. Creating a reliable foundation will require the use of concrete, concrete blocks, sand, gravel, crush stone, cement, brick, wood, and reinforcement.
Laying the foundation
A significant discrepancy between the foundation and the philippines numbers leads to deformation and destruction of the greenhouse. A 150x150mm beam treat with an antiseptic is plac in a 20cm deep trench, according to the dimensions of the greenhouse being erect. Roofing felt will serve as protection from the effects of soil moisture. Rows of beams are connect with metal pins. For significant protect soil structures, a more durable foundation will be requir. A concrete strip foundation is consider an inexpensive and practical option. A 30cm deep and 35cm wide trench is dug around the perimeter of the propos structure. The bottom is cover with a 10cm layer of sand. Anchor bolts with a diameter of 12mm are install in the pour concrete around the entire perimeter. After hardening, 2 rows of bricks, roofing felt and a wide base beam are laid on the concrete, leaving space for the anchor bolts free.
Erection of the frame
The upper parts of the corner posts of the wooden frame of the greenhouse are connect to each other. Then, vertical supports are plac along the entire perimeter at a distance of 1 m from each other, using parallel strapping. The parts are fasten together with metal corners. In a long greenhouse made of wood and polycarbonate, made with your own hands for growing tomatoes, it is better to provide 2 doors on opposite sides. For them, vertical supports are install at a distance of 100 cm, allowing you to roll in a cart. For better ventilation of the cover structure, vents are provid at the intersections of transverse and longitudinal structures.

The ridge beam and rafter elements are fasten together using plywood strips reinforc with metal corners.
Covering a wooden greenhouse
Correct connection of polycarbonate to a wooden frame will guarantee long-term use of the clos ground structure. There are several methods of fastening: The following means will save carbonate sheets from premature thermal destruction: profile joints, provid gaps, holes exceing the diameter of fasteners by 2-3 mm, thermal washers. It is better to carry out work on covering the greenhouse with polymer plates at a temperature of 18-20 ° C. Covering the wooden frame is accompani by a preparatory process of cutting, drilling holes, end sealing.
Installation of doors and vents
The design of a wooden greenhouse cover with polycarbonate retains heat well, creates the prerequisites for an increase in temperature, and therefore must provide for the presence of doors and vents. The purpose of the clos-ground structure, its size, and the crops being plant affect the design of the door. A long greenhouse assumes two wide (100 cm) entrances, allowing free transportation of garden tools and ventilation of the room. The polycarbonate blank is fix to the door frame knock together from 50×50 mm beams. Handles are attach to the door and it is hung on hinges. The presence of vents ruces the possibility of plants becoming infect with fungal diseases and promotes fruit setting (high temperature and humidity lead to pollen sterilization.
