*NOTES: Monitor soil moisture so seeds do not dry out or are not saturated with water. Overwatering can lead to damping off. 

Suggestion on growing medium: Start seeds in a specific seed-starting mixture. We suggest using a sterilized growing medium for seed starting mixes as well as potting mixes. See Pro-Grow's line of heavy-duty soil sterilizers (click here).
