  1. hey what is the best way to raise or lower the PH in my soil . id like to stick to my organic flow so no chems . im not sure this is the problem yet as i havent checked my ph yet (broke!)hope the dont kick before the funds come in .
  2. HIGH All, Basically, Marijuana plants will thrive in a pH of 6.5 to 7.0.
    To make acid soil less acid, you need to add alkaline materials such as lime. To make soil more acid, you need to add acid materials such as peat moss, sulfur, iron sulfate or aluminum sulfate. After adding the proper amounts of acid materials or lime, it does take some time for changes in pH to occur in the soil.

  3. everything is made out of chemicals, organic or no-organic, it all uses some type of chemical.

    and for those who don't know, iron sulfate means an old rusty chain or rusty nails. I learned that from my grandma when she wanted her hydrangea bushes to be blue
