With our CNG certification I can only use organic potting soil. Wetting agents are prohibited as well. So I am using Fafard super-fine germination mix. Spaghum,verm and perilite. On average it is take between 23 and 29days for the sets to root/ set true leaves well enough to transplant. (In unheated greenhouse no artificial light)
What would you add to the mix to help build the strongest plants? What ratios? thanks Tate
