  1. Hey,
    I got some clones rooted in some rockwool that i want to plant into soil. I know rockwool should have a lower ph than soil. So when i plant them what should the ph be at?
  2. normally in rockwool you want like 5.5 , but if you are transplanting into soil and the roots are gunna be growing into the soil, the ph of the rockwool won't apply.
    Soil ph is 6.something not sure exactly...
