hey i started my grow 3 days ago and i had my 8 lamp t5 h0 like 3-4 inches away from the just planted seedlings. The ready grow bark dryed up quickly with the light so close so i was forced to water multiple times a day. They shrivled up and im still watering them but im pretty sure they're dead. How high above my plants should my light be, its in a gl 60 tent. thanks for any help. i replanted new seeds and raised the lights about a foot
