How can Harvest Hero be used with Peat Moss or Coco Coir without a pH adjuster being involved?

We recommend using Canadian Sphagnum peat moss, which is just slightly acidic. pH values for Canadian Sphagnum peat moss are well within the acceptable ranges of cannabis culture. Be mindful, Diatomaceous Earth (DE) is slightly alkaline in nature, which will have a buffering effect over the slightly acidic nature of Canadian Sphagnum peat moss, rendering the mix neutral pH.
