F/2 Phyto Fertilizer Set

Two-part F/2 phytoplankton fertilizer, Macro + Vitamins and Trace-Metal Complex for fast, stable, high-density micro algae cultures. Separate bottles preserve vitamin potency.

Grow dense, reliable phytoplankton with the F/2 Phytoplankton Fertilizer Set. This two-part system pairs F/2 Macro | Part 1 (Macronutrients + Vitamins) with F/2 Trace | Part 2 (Trace-Metal Complex) to deliver balanced F/2 nutrition for rapid cell division, robust photosynthesis, and long-term culture vitality. Keeping vitamins separate from trace metals protects potency and extends shelf life.

Benefits
