#Plant your tomato seeds in a starting mix. Wet your seed starter mix or potting soil with fresh water until it is moist. Fill a seedling starter tray with a moist mix or soil. Poke one hole in the soil of each cell—the hole should be ¼ inch deep. Insert about 8 seeds into each hole with a tweezers or your fingers. Cover the holes with moist soil or mix. | #Plant your tomato seeds in a starting mix. Wet your seed starter mix or potting soil with fresh water until it is moist.

#Promote germination with consistent heat and water. Germination is the process of transformation from a seed to a seedling. Tomato seeds will germinate within five to ten days. There are several actions you can take to speed up this process and to ensure its success. | #Promote germination with consistent heat and water.

#Move your sprouted seedlings to a sunny or artificially lit location. Tomato seedlings and plants require between 12 to 16 hours of light each day. Without adequate light, tomato plants will become weak. As soon as the seeds have sprouted, discard of the cover and provide your seedlings with ample light. If you have a south-facing window, place the cells directly in front of the window. If you do not have a south-facing window, shine a grow-light or a fluorescent light on the seedlings. | #Move your sprouted seedlings to a sunny or artificially lit location.

#Transplant your seedlings into large pots. As soon as your seedlings grow one to two sets of leaves, they are on the verge of outgrowing their cells. At this time, transplant the seedlings into a pot that is large enough to hold a mature plant—a five to ten gallon container is ideal. | #Transplant your seedlings into large pots.

#Water your plants when dry. After you transplant your seedlings, it is imperative that you continue to water the plants regularly. Assess the soil everyday for dryness by sticking your finger into the soil. If the soil is dry, water the the plant. If the topsoil is dry but the rest is moist, water at a later time. | #Water your plants when dry.

#Create day and night time light conditions. While tomato plants require plenty of light, they also need a period of darkness. If you are using artificial lights, you need to mimic the natural rising and setting of the sun. Turn on your lights in the morning. After twelve to sixteen hours, turn off the lights and allow the plants to rest in the dark. | #Create day and night time light conditions.
