Purpose: The purpose of this thread is to find a way eliminate the White Fuzzy mold, and prevent it from coming back. Setup: 24x12 inch humididy dome Heated Pad 10x clones in rockwool cubes 98%-100% Humidity 72-74* F inside dome Problem: Two out of the ten have developed the circular white fuzzy mold. I'm afraid it will spread and become out of control. I believe the cause of this is the heater pad I had to put underneath the dome, considering I did not have this problem since before the heater was added. The heater is essential during the cold time of the year. What I have already done: I sprayed them yesterday with 3% H2O2 and instantly destroyed it, then 24 hours later the same 2 out of the 10 have the circular white mold. I thought maybe the clones were ready to hold moisture so I took the dome off after I sprayed them and they wilted in 20 minutes so roots have not yet developed enough.. Looking forward to hearing what the forum thinks! Thanks in advance for your help!
