With some preparation, it is entirely feasible to grow tomatoes indoors from seeds.
Depending on the variety, the time from sowing to harvesting tomatoes in an apartment can range from 50 to 80 days.
Growing one or two pots of cherry tomatoes at home has almost become a tradition, and they thrive well when placed near a sunny window.
Moreover, tomatoes can bear fruit throughout the year, as there is no risk of frost indoors.
Tomatoes are warm-loving plants and also prefer moderate humidity.
As long as your potted tomatoes in the apartment receive the necessary light and water, the temperature and humidity in your home should not pose a problem.
However, keep the tomatoes away from vents to protect them from hot or cold drafts.
Tomatoes require at least six hours of light per day for fruiting, but eight or more hours of light will yield the best results.
