Hydrodynamics Ionic PK BOOST Plant Nutrient 0-5-6 - 128 oz (1 Gal)

Extra Phosphorus and Potassium for Late Flowering - 128 oz Liquid

Late in flowering, plants often need more phosphorus and potassium than a standard bloom feed supplies. This liquid supplement adds both on top of your existing program, with an analysis of 0-5-6 and no nitrogen. It mixes with water in all proportions, so it blends into a reservoir or feed tank without special handling.

The 128 oz (1 Gal) size suits growers who run bloom cycles regularly and want enough on hand to finish several batches. At the labeled rate of 2 mL per liter, a gallon covers many feedings for home gardens and small to mid-size indoor rooms.
