Eggplant varieties grown in greenhouses are expensive because they are generally hybrid eggplants. Therefore, healthy seedlings should be generated without harming the seeds. Drilling can be done either by scattering the seeds into boxes by hand (under appropriate temperatures) or by using the row planting system.
After drilling, the area must be covered with compost screened to 1/5 inch particles. Plants should be kept out of sunlight as they emerge and will gradually adjust. When the seed leaves fully emerge and the first real leaf is seen, it is time to transplant them. Since transplanted plants are sensitive, they should be kept out of direct sunlight for 2 to 3 days. Seedling bags should be placed in such a way that there will be enough space between them so that the will not touch each other.
God seedling growth should be allowed so that when the seedlings are ripened, the flower buds will form with equal width and length. Plantation should be done in a cold atmosphere and re-irrigation may be necessary depending on the climatic conditions. The most appropriate temperature for eggplants is between 77 to 86 F. If temperatures in the evening drop below 60 F, the fruit set will not emerge. In order to provide insemination under these conditions, plant growth regulators are needed. Development decelerates under low temperatures and eggplants begin to freeze at 32 F.
