Forgot to mention... The seeds were incubated in an Ice Cream tub with kitchen towel and PH 5.5 tap water. After the seeds had cracked they were placed in the propagator with the lights turned off until they surfaced. As soon as they surfaced the lights went on for 18hrs a day. I have the lid on the propagator as I want a high humidity until they have established a good root zone. The Intake fan is on blowing cold air around the growroom, this helps the propagator not to dry out as quick!
