The right containers are very important as you don't want them to be too big or too small. Choose a container that is at least 2-3 inches deep and about as wide
Before you start putting the soil into the container make sure you get the soil moist. You do not want the soil dripping wet or the consistency of mud.
Start with moist soil and water at least once a day. If you live in a drier climate, you may need to water twice a day. Check your soil to see if it is dry to the touch.
Seeds and plants need air to grow and thrive. Adding a fan to your set-up will help the air to circulate more and can also prevent a seedling disease called damping-off.
