No. I dont use anything on my cuttings. B1 soak, Dip n Grow, trim n stick. Plain water till roots. This problem was happening during the first few days in the dome. New room and the humidity out of control. Too high for the domes open all the way but not high enough to remove them. I actually winged it today as I had to cut and used Cloud Cover. So far so good! Thank you for responding!
