Pepper seedlings waking up to the morning sun. Pepper seeds can be finicky, some taking 30 days or more to germinate, so I germinate them under controlled conditions in a grow dome that sits on a heat mat so the temperature inside of the grow dome is about 90 degrees F. Once they germinate I put them into recycled yogurt cups until they get a second set of leaves then I put them in larger pots for the terrace. I used to put them under a LED grow light for 18 hours/day but I don't see much difference between that and regular sunlight hours. These will go back inside before 10am so the sun doesn't fry them. All of these germinated in the last 24 to 72 hours.
