Tomatoes have their origin from South America, and the name was given to them from the Italian pomo d'oro, translated as "golden apple", and from the French tomate. Both names are used in Russian.
The tomato was brought to Russia in the 17th century as an ornamental plant. Russian scientist agronomist A.T. Bolotov achieved the recognition of tomatoes as a vegetable crop. Even 70 years ago, scientists with the help of selection were able to improve the varieties of tomatoes and their diversity. Literally at the beginning of 2000, breeders from Russia bred the Negritenok tomato - this is an author's series that is successful with our gardeners.
Amateurs grow a varietal variety of black tomatoes both in greenhouses, and under a film, and on balconies and on window sills.

The temperature can be lowered when the first shoots appear from + 24C to + 12-15C during the day and 8-10 C at night. At this time, seedlings should be watered moderately. Apply top dressing at intervals of 2-3 weeks.
The greenhouse environment is comfortable and conducive to good plant growth, while at the same time it is a favorable environment for various insects, viruses and fungi.
