Hello mooney growing a moldy flat of grass is very common to growers learning about growing grass.I grew alot of moldy flats for about a month before I figured out the differance between moist not WET!Try growing the grass without watering the seeds after you put them on a moist growing medium.See how well they do and if the mold is still trying to take over.You shouldnt compare your growing to a flat that was grown inside a greenhouse by a commercial grower. Juice dosent make hormones but high consumption of suger is bad for hormonal control.There are many low suger veggies that can help control high suger issues that drive hormonal imbalance.Try radishes and Celery along with cucumbers then mix in a green such as parsley or a good lettuce.Blends like this will bless your body and help your body return to its natural state of balance.Happy juicing and may you be blessed with vibrant health.Jeff.
