Sforza, yes it's for root production. I give it a little dab on cut area hoping it would relieve stress from topping late. It seemed to work very well. No plants showed any kind of stress. Some that were topped started flowering two days later. Stress would have prolonged flowering imo. As we discussed earlier about flowering. I'm staying with the Alaskan brand moorbloom for the balance of this season. I will research other options after harvest. Not being 100% organic bothers me. It's still better than any other product I have used. Peace
