This is my first experience with an ebb and flow system and curious what everyone is using for flood times etc. I have 6 girls growing. 3 each in two tubs...flooding to 1/2" below my rockwool which sits in Hydroton. I flood for 15 minutes 5 times a day but I am thinking they are getting too much. Both trays are also filled to the top with Hydroton to protect roots from light etc.
