A good quality phosphorus booster should derive its phosphorus from multiple sources and DUTCH MASTER POTASH PLUS has been redesigned to contain no less than 6 different phosphorus sources that have been carefully balanced with essential co-factors and micro nutrients to prevent any unwanted lockout, such as magnesium or zinc.

POTASH PLUS was reformulated to provide the next best thing during those last crucial weeks of flowering. POTASH PLUS can also be used for the entire flowering cycle for those that prefer not to foliar spray at all during the flowering period.
