transplant your tomato plant in an appropriate container. To grow the tomato plant large enough to produce fruit, you will need to grow it in a large container. A plastic 5-gallon bucket is ideal, but a larger container will also work. Avoid using anything smaller than about 5 gallons Purchase grow lights for the tomatoes. Growing fruits and vegetables indoors requires the use of full spectrum fluorescent lamps, often labeled as grow lights, plant lights, or aquarium lights. Two tubes will generally be sufficient for growing 1 tomato plant. You can find several types of stands and mounts for these lamps at hardware stores and nurseries Aid the tomato plant in pollination. When grown outdoors, tomatoes rely on the vibrations created by bees, birds, and the wind to distribute their pollen and develop fruit. To simulate this effect, gently shake the plant's flowers daily or place a fan nearby to create airflow. Grow the tomato plant as you would outdoors. Aside from the special considerations mentioned above, indoor tomato plants need little additional care that is not required by outdoor plants. Turn the grow lights on during each day and off during the night to simulate the rising and falling sun. Maturity times will vary based on the variety of tomato planted and the conditions in your home.
