Quick Answer

Professor's Organic Flower Boost is an OFC-approved liquid PK enhancer for flowering and fruiting plants. Its typical analysis is 0.578% nitrogen, 0.982% phosphorus and 3.39% potassium. Mix 2–4mL per litre of water during the flowering stage and check pH after mixing.

Product Description

Professor's Organic Flower Boost supplies phosphorus and potassium in a concentrated organic liquid designed to supplement a flowering-stage nutrition program. The manufacturer describes the formula as being derived from seaweed, fish, complex sugars, amino acids, humic acid and fulvic acid.

The product carries the Organic Food Chain (OFC) approved logo. Professor's Nutrients states that OFC is an approved organic certifying body recognised by the Australian Department of Agriculture. Use this additive as directed alongside an appropriate base nutrient program; it is not a complete fertiliser by itself.
