Tomatoes are a popular home garden crop and easy to grow. Many gardeners start their tomato seeds indoors in the winter to get a head start on the spring growing season. Tomato seeds do best in a sandy loam type of soil but germinate fine in plain sand. Because sand has a tendency to dry out quickly, you will need to check the moisture content of sand periodically and moisten it if it appears to be drying.
Pour the sand into the planting pots. Water it well and allow the excess water to drain completely from the bottom of the pot.
Use the tip of the pencil to poke 1/8-inch deep holes in the sand and drop on tomato seed into each hole. Cover the hole with sand.
Cover the pots with plastic wrap, but leave one corner just barely open for ventilation. Keep an eye on the soil, and if it begins to dry out, use the fine mist setting on the misting bottle to lightly spritz it.
Place the pots on a heat mat set to 75 degrees F. Tomato seeds do not have any special light requirements in order to germinate, but they do require warm soil.
Remove the plastic wrap when the seedlings are 1 week old and place them in an area with lots of light, but not direct sun.
