Only if absolutely neccessary spray shit on dope plants (h202, milk etc),as it usually makes mold prob worse due to adding moisture.A much better bet would be to make sure they're in low humidity envirinment, osc fans, dehumidifier to lesson the chance of this happening in the future.ive read a few different places that is good choice
