Torn between soil mediums: Peatmoss & Perlite or Promix BX mycorrhizae. If I use peatmoss & perlite the soil medium would be 30% peat 30% perlite and 30%WC and compost. If I use promix bx what would the ratios be . Promix has 85% peatmoss and perlite and vermiculite plus lime as a ph adjuster . I can get the promix on sale now and I've used peatmoss with my old soil mixes in the past but never tried promix before just wondering if any of you organic growers have used it in your outdoor grows. Im basically using the 8 step soil recipe in your tutorial page and 30 gal smart pots.
