Slow Tomato Germination?

SueCT · January 26, 2017

I don't know about anyone else, but I germinate my seeds on a heat mat with a thermostat and with a loose covering of plastic wrap. I started out using 80 degrees as a set temp and then eventually decided to reduce that to 75 degrees. But unless there is a way to determine the optimum temp for each seed variety, not sure how I can get better germination. I already have an average of about 90% germination except for the odd variety or pack of seeds that I have trouble with. It is still a mystery to me why when all other others do well at the same temp. If anyone has information about the germination conditions preferred by a specific variety please share.
