How to Grow Tomatoes With a Light at Home


Even without a gardening area outside, it is possible to grow big, juicy tomatoes at home. With proper lights, you can have a bounty of tomatoes, so much that you will have enough to share with friends and family. Novice gardeners and expert gardeners alike can successfully grow tomatoes with a light. Encourage children and teens to grow tomatoes with this method and take pleasure in the delicious results.

Step 1

Mix 1/4 gallon of peat, 1/4 gallon of organic potting soil, 1/4 tsp. of granular time-released tomato fertilizer in a small bucket.

Step 2

Fill a 1-gallon potting container half-full with the potting mixture. Water until the water drains from the bottom of the container.

Step 3

Remove a tomato plant from the original potting container. Gently squeeze the root ball, loosening the root system. Shake the plant slightly, releasing any excess potting soil.

Step 4

Dig a hole in the center of the prepared potting container (from the previous step) with a small garden trowel. Make certain the hole is approximately 1-inch deeper and wider than the tomato plant's root ball system.

Step 5

Select a location for the newly planted tomato container. Avoid a window with direct sunlight to avoid leaf and stem burn.

Step 6

Place a light 1-foot from the container. Focus the light on the container. Make sure the light has a grow bulb in it.

Step 7

Attach a timer to the light and set it for eight hours. Turn the light and timer on. The timer provides daily light without having to manually turn on and off the light.

Step 8

Rotate the tomato plant one-fourth turns daily, providing equal light distribution and preventing bent plants from growing toward the light.

Step 9

Water the plant every three days until water drips from the drainage hole.

Step 10

Harvest the tomatoes one day after ripening begins and allow shelf-ripening.

Step 11

Repeat steps for additional tomato plants.

Tips and Warnings

  • No additional fertilizing is needed since the potting soil mixture contains time-released fertilizer.
