Same as rock wool

  1. Anyone have experience with grodan mini blocks? How do you prep them.
     
  2. Read the directions on the package.

    Soak em in 5.5-6.0 water overnight.
     
  3. Yeah that's what i thought. But the package says soak in 5.5 for 10sec!! That can't be right. Everywhere I've read says the same as you overnight. I was thinking maybe grodan was something different. Please help my beans sprouted, just waiting on tap root to get a lil longer.

    I soak for 30min-1hr and never had any problems. Just make sure to get your ph right. That's the important part.
