  1. whats up guys? i just germinated some seeds in rapid rooters and after they rooted i placed them in rock wool blocks on my table under a shoplight. after two days i noticed some white stuff on the rapid rooters but not on the blocks. is that powdrey mildew or the beginning of algae? i can whipe it off and it comes back. i havent use nutrients just distilled water so its not salt buildup thanks
     
  2. I used rapid rooters for my first attempt at cloning and they all died...I figured there is a reason why the pros use rockwool..never again will I buy rapid rooters..they are shit!!!
     
  3. Probably mildew, I've used RR for a long time with great success.
