i have 3 lights. 2x150w hps, 1x250w hps.

i planted them about half an inch down and i dont know the temps. one of them sprouted but then it died, just popped the seed put and curled up. ahhh this is annoyin. the strain is kaya. i got them from nirvanas 100% female range. do u think the seeds should be ok??
