You can place the container in a plastic bag or cover it with a sheet of plastic. Allow for some air to circulate but don't let the mix dry out. Dry seeds will not germinate. #6 Patiently Wait for Germination Place the germination container in a warm location out of direct sunlight. Light is not needed during the germination process, but will not be harmful as long as high temperatures are avoided. Tomato seeds usually germinate within 5 to 10 days when kept in the optimum temperature range of 70 to 80F (21 to 27C). Germination is delayed by lower temperatures and accelerated by higher temperatures. Temperatures below 50F (10C) or above 95F (35C) are detrimental to germination.
