Polycarbonate to cover greenhouses in practice recently entered. This is a modern and very comfortable material. In order to get a good crop of tomatoes, the gardener should be aware of the peculiarities of agrotechnics in the greenhouse, which has a coating of such plastic and the most suitable varieties.
In this article we will describe how planting tomatoes in a polycarbonate greenhouse is carried out, what should be the humidity and light, as well as which varieties are best suited.
Features of the growth of tomatoes in a similar structure
The basic techniques of farming tomatoes in a greenhouse made of polycarbonate are standard. This is getting seedlings, planting, tying, pasynkovanie, fertilizing, watering, etc. But there are some moments dictated by the specifics of this material.
Humidity
Polycarbonate greenhouses are in fact almost airtight. There is no "natural" ventilation in them, whereas ordinary greenhouses always have some unnoticed gaps or random openings. Water vapor in a polycarbonate greenhouse does not have the ability to volatilize and remain in the atmosphere.
This leads to an increase in air humidity, dampness and the formation of condensate. This in turn increases the likelihood of spreading fungal diseases such as late blight, powdery mildew. For, In order to effectively ventilate the entire volume of a polycarbonate greenhouse, it is necessary to have in it not only side windows, but also upper windows.
Important: Before planting tomatoes, the greenhouse should be carefully treated to destroy the spores of pathogenic fungi, as well as other pests.
Illumination
Polycarbonate, with all the transparency, is still inferior to glass. With even a slight lack of light, light-loving tomatoes will grow worse, and, of course, yields will decrease. Therefore, it is necessary to carefully consider the placement of bushes in the greenhouse so that the incoming light energy is distributed among plants as evenly and efficiently as possible.
When buying or building a polycarbonate greenhouse, you should carefully select the location for placement - so as to minimize the possible shade that surrounding trees or buildings can cast on it.
What kind of vegetable can I choose?
