The book refers to the cultivation in protected soil of both heat-loving crops - cucumbers, tomatoes, peppers and eggplants, as well as some cold-resistant green plants in order to obtain an early harvest. All these vegetables are highly appreciated as very tasty and useful and vegetable growers try to grow them even in the smallest areas, but not everyone manages to get a good harvest of tomatoes and cucumbers, rarely anyone grows in the middle lane, and even more so in the northern regions, peppers and eggplants.
