When choosing a new greenhouse, you should pay attention to 5 important parameters.
Among them, according to the expert of the online publication Belnovosti, scientist-agronomist, landscape designer Anastasia Kovrizhnykh , are the thickness of the profile metal, the cross-section of the frame profile, the density and thickness of the polycarbonate, the metal coating and the sun-protective UV layer of the polycarbonate.
However, there are still a few necessary steps.
Ask the seller to provide you with a sample of polycarbonate to conduct an experiment. If, when you press on a piece of polycarbonate, it cracks, it is not the right choice.
The same sample should be measured with a ruler or calipers. It may seem surprising, but the parameters sometimes do not match the declared ones.
Do not hesitate to check the certificates and markings for the materials from which the greenhouse is made.
The easiest way to find a reputable seller is by word of mouth.
If there are no avid gardeners in your circle, use the reviews left on forums on vegetable growing topics - reviews from the supplier's website do not always reflect the real state of affairs.
