Successful indoor propagation involves providing the seeds with a healthy growing environment until they have developed sufficiently to survive in the outside soil. This includes using sterilised equipment and hygienic materials to reduce the risk of fungal diseases; the right amount of light and water; and a constant evaluation of their conditions, thinning the seedlings out and then hardening them off when they are more fully grown.

In this section, we take a look at all the stages involved in successfully growing plants indoors from seed; from preparing the growing medium to hardening the developed plants off and potting them on.
