Stop adding stuff to your clones. It may be one of your problems. The only way that you can kind of figure it out is to start isolating products. I also didn't think to ask. Did you clean your aero cloner before using it? Domes are a nice safety item as well. I just don't need them where I am. How are your clones doing since being under the dome with the rockwool? Are they in rockwool in the aero cloner?
