First indoor grow with LED lights

Some seeds failed to germinate , might have been my fault. Made a second run at germinating seeds and was successful, 5 days later and I have placed the sprouts , tap root down into 2cm of soil that was lightly sprayed with filtered mountain water (ph 6.8) and covered loosely. This is day one of the tent setup running on low air in/out , fan on low . One light running at 25% for 16 hours .
