General Hydroponics - FloraPro PK+ Liquid
Brand: General Hydroponics
General Hydroponics FloraPro PK+
FloraPro PK+ is a zero-nitrogen phosphorus, potassium and sulfur supplement with a guaranteed analysis of 0-4-6, used to bulk and ripen crops. By reducing nitrogen delivery during flowering while holding target P, K and S levels, it supports bloom development and triggers natural ripening signals. It is a soluble liquid concentrate built for commercial-scale operations. It works alongside the FloraPro Bloom A and Bloom B base nutrients.
PK+ is intended for use in continuous liquid feed programs for hydroponic use only, with a normal feeding range up to 10 mL per gallon. The published graduated schedule is 2 mL per gallon in early flower weeks 1 to 3, 4 mL per gallon in mid flower weeks 4 to 6, 5 mL per gallon in late flower weeks 7 to 8, and 7 mL per gallon at finish in week 9. It is compatible with automated fertigation systems and drip irrigation. Adjustments may be needed based on environmental conditions and water quality.
