I have been a tomato grower since 2008 when I grew my first tomatoes from seed.
Growing tomatoes from seed takes time and care, but ultimately it is not hard and the results are well worth it.
You will need either a grow light setup (cheap shop lights) or a south-facing window that gets plenty
of sun (if you live in the southern hemisphere, you will need a north-facing window).
Use this instructable as a guide to growing your own tomatoes from seed. UPDATE: Check out my new Web site on growing tomatoes.Grow Your Tomatoes
