I have been using rockwell for 12 years and i think it is great . I just use white cotton rags to cover it up around the base of the plants.
chudderhead Reviewed by chudderhead on . Algae & Rockwool - How do you deal with it? I have some on the tops of my 6" cubes and some on my grow mats (not severe but still there). Most of my plants look good but a few look kind of wilty and weak. Anyone out there with the same problem and any idea on how to deal with it? Also for next time how can I prevent it from starting in the first place? If this is addressed somewhere else I'm sorry but I looked around the site first and couldn't find any conclusive info. Thanks!:thumbsup: Rating: 5
