Hi,
You should leave the heating mat/pad on low all the time. If you are using artificial lights, you should provide about 16 hours of light each day to start your seedlings. A timer is an excellent way to make sure the seedlings are getting enough light. Here is some information from the U on starting seeds indoors. Scroll down to see the article.
