Hello, I just switched to rapid rooters for my cloning needs. I have 350 Nice little clones already popping roots through the sides. Unfortunately, I am seeing this white growth appearing, mostly on the top, outer edges of the rapid rooter plugs. The plants look healthy as can be, but it has me worried. I have been keeping them wet with a light solution of clonex and ro water. I didn't soak the plugs in anything. I'm guessing this is some type of mold that will not harm my plants since it's not effecting them yet, but I'm wondering if I shouldn't must the plugs with some h202 and water? I saw there was an old thread about this with varying responses, but I thought I'd see off anyone else had any experience with this recently, and if anyone has any suggestions? Thank you.
