Hey, I am very new to growing (1st time) and I think I killed my White Widow seeds. I germed them on june 10th using plain white paper towels, zip lock bag and heating pad. They started to sprot so I put them in pot with organic soil, with little water and under a plant light. 2 days later there were no more sprot. Are they really dead or is there something I can do? These were very high quility seeds. Any ideas? Thanks!
