Had 2 showing roots today.I'll use a seedling mat next grow.Gotta get 1.They are on the floor near the inlet air. I think that would be an issue as to the length of time they are taking to root.Humidity was not a problem.The dome kept that at a maximum... The soil, and the bottom of the tray they are in, is not as warm as they should be. Outside air is freakin' my room temps out. Mother Nature... I love her!
