It was designed based on Logan Labs soil testing and saturated paste testing. We wanted to design a premium plant and mineral based potting soil. Along with that it had to be a compost based soil without any of the low quality ingredients normally in organic potting soils. Besides being clean, the goal was that it would test High in available calcium and low in available sodium. After dozens of lab tests and real world tests, this potting soil mix became a clear cut favorite or BuildASoil customers. It was designed to work with all plants by keeping excess to a minimum and balance as the all goal. Because the recipe is so balanced it has the ability to be run as a No-Till Soil with added topdressing or to be run as a highly steerable recipe for organic feeding. Compared to our other recipes this is our most popular all around potting mix. Excellent for starting seeds or full term growth

THEY DO NOT sterilize any of our compost or Potting soils during the manufacturing process and as a result it will contain a plethora of life. This could be beneficial mites, fungus and microbes as well as, from time to time, unwanted fungus gnats. While they do their best to keep anything unwanted to a minimum we cannot guarantee it. They always recommend purchasing beneficial insects to combat this possibility and/or learning best practices to avoid population explosion.
