Liquid ProBiotic Food (PBF) for plants is sold as a concentrated liquid (NPK is approximately 22-1-22 on a dry basis); normally mixed with water to make a 20% PBF/80% water fertigation liquid. Liquid PBF is available through a “milk-man-style” delivery service to growers on Vashon Island, and limited points of sale and pop-up giveaways.

PBF for Plants Mix no 7 is our best formulation: composed of the most interesting and complimentary ingredients to make the best plant food possible.
