Custom mixes (this includes all soil-based mixes) require a minimum 5 working-day notice to process. Listed below are some of the common custom mixes used in the Plant Care Facility. These mixes are normally steamed and delivered by PCF staff in ½ or 1 cubic yard steam carts. Steam carts with leftover soil will be picked up by PCF staff after one to two weeks of no activity unless otherwise instructed.
We will also make up custom mixes to your specifications. See also our listing of soilless mixes.
