Then place the heating mat under the tray and turn it ON. The release by mat will keep the seeds warm and they will sprout fast and easily.

75 to 85 degrees F is the ideal seed germination temperature. Install a thermometer in the room to know about the temperature. When you see half of your seeds are sprouted then turn OFF the seedling heat mat.

Do not forget to water the seedlings you need to keep the soil moist all the time. Remember that shishito peppers need 16 hours of minimum light per day. Fertilize seedlings with diluted organic fertilizer. Let the seedlings in the seed starting tray until each of them develop few leaves.
