Probably, every gardener at the beginning of the new season asks the question: “What varieties to plant this year?”. This problem is especially relevant for those who grow tomatoes indoors. Indeed, in fact, the tomato is not adapted for such conditions, and there are several reasons for this, which will be discussed below.
How to choose the best variety of tomatoes for a polycarbonate greenhouse, what is the peculiarity of growing tomatoes in greenhouses – this article is about this.
What does a tomato need?
For normal development тomamas of any variety need certain conditions:
- Sufficient amount of sunlight. Not a single polycarbonate greenhouse can provide 100% light absorption by plants, because the walls of the greenhouse are not absolutely transparent. Part of the light is absorbed by the plastic itself, an even larger dose is lost due to the contamination of the polycarbonate. As a result, the tomatoes are left with about half of the natural light.
- A certain level of humidity. Yes, tomatoes love water – these plants need to be watered often and plentifully. But high humidity is detrimental to tomatoes, and in a greenhouse it is about 100%. Whereas tomatoes need only 65-70%. In such conditions, pathogenic microorganisms multiply very quickly, which leads to plant diseases and their death.
- Tomatoes do not like too high temperatures., in such conditions, their pollen becomes sterile – the flowers are not pollinated. And in a polycarbonate greenhouse it is often very hot, 30-degree temperature there is the norm.
To grow healthy tomatoes, you need to minimize factors that harm plants. But it is almost impossible to do this in a greenhouse, so you need to choose special varieties of tomatoes for polycarbonate greenhouses.
