PROMIX BX, 3.8 cuft.

Serious horticulturists use this PRO-MIX growing medium when they need a stable, growth-promoting base for container applications. PRO-MIX BX uses biofungicide to ward off disease and mycorrhizae to retain moisture. Combined with a 75-85% sphagnum peat base and an introductory fertilizer, the result is PROMIX soil that is productive in many applications. Use it to start young foliage plants in trays, transplant vegetables to larger pots, grow perennial flowering plants in hanging baskets and much more. The starter fertilizer will be used up within 10 days, at which point you should begin a new program.
