The ideal harvesting time for tomatoes is around 70-90 days. Accordingly, plant the seeds and transplant the plants. 

To prevent physiological diseases of the tomato plants, grow a tomato in a regulated atmosphere. 

Keep the tomato seeds in 16 hours of light and provide 7-8 hours of sunlight to the well-grown tomato plant every day.

Tomatoes should be grown in an area with a good drainage system and with no tall trees or shrubs around.
