When germinating seeds just put a cloth in a plate. Fold it in half and keep it moist. The warmer it stays the faster the seeds will grow (heat activates growth). Dont let it get above 95* though. Let dry seeds soak in glass of water and swirl them around hourly. I let mine soak for 3-5 hours and they open up within 48 hours. Some seeds are no good and there is nothing you can do... accept it. That hair you see isn't mold, Its normal. I have 9 2"-5" seedlings that have the same hairs.
