Pre-EMPT Organic Hydroponic Fertilizer is a fully organic, fermented molasses-based nutrient concentrate designed to power hydroponic systems for leafy greens, herbs, and vegetables. It can replace conventional hydroponic fertilizers, offering a clean, naturally derived formula packed with macro- and micro-nutrients, amino acids and vitamins.

Key Features & Benefits

• OMRI-Listed & Plant-Based Formula
  Certified for organic use, Pre-EMPT is derived from natural plant extracts and fermentation, meeting organic standards.

• Complete Nutrient Spectrum
  The five-stage fermentation process integrates molasses with other natural compounds to deliver essential macro- and micro-nutrients, as well as humic/fulvic acids and vitamins, forming a “full spectrum” nutrient formula.

• pH-Stable & Easy to Use
  Pre-EMPT typically comes in at around pH 4, reducing the need for “pH down” adjustments. While many growers don’t require external pH control, some water sources may vary and occasional adjustments (e.g. citric acid) are acceptable.

• Extended Reservoir Cycles
  Growers using Pre-EMPT have achieved reservoir stability for up to 90 days or longer between full flushes, depending on system and crop conditions.

• Supports Faster Crop Turn-Around
  Some basil growers report harvests 5 days earlier compared to conventional fertilizer regimes.

• Emitter & System Friendly
  When used properly, Pre-EMPT does not clog ¼" emitters, which is uncommon for many organic fertilizers.
