Probably every gardener at the beginning of a new season asks the question: “What varieties should I plant this year?” This problem is especially relevant for those who grow tomatoes indoors. After all, in fact, the tomato is not suitable for such conditions, and there are several reasons for this, which will be discussed below.
How to choose the best variety tomatoes for the greenhouse made of polycarbonate, what is the peculiarity of growing tomatoes indoors - this article is about that.
What does a tomato need?
For normal development Tomatomas of any variety require certain conditions:
- Sufficient amount of sunlight. No polycarbonate greenhouse can provide 100% light absorption by plants, because the walls of the greenhouse are not completely transparent. Part of the light is absorbed by the plastic itself, and an even larger dose is lost due to contamination of the polycarbonate. As a result, the tomatoes are left with approximately half of the natural light.
- Specific humidity level. Yes, tomatoes love water - these plants need to be watered often and abundantly.But high air 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, under such conditions their pollen becomes sterile - the flowers are not pollinated. And in a polycarbonate greenhouse it is often very hot; temperatures of 30 degrees there are the norm.
To grow healthy tomatoes, you need to minimize plant-damaging factors. But it is almost impossible to do this in a greenhouse, so you need to choose special varieties of tomatoes for a polycarbonate greenhouse.
