      Coco Nutrients That Feed Clean from Veg to Flower

      Coco nutrients matched to your medium

      Coco coir holds potassium and binds calcium and magnesium, so a generic feed leaves gaps. These bases are formulated for soilless media — buffered, pH-stable and built for clean uptake in coco and hydro systems.

      FAQs

      Do I need special nutrients for coco coir?

      Yes. Coco naturally holds potassium and binds calcium and magnesium, so coco-specific base nutrients are formulated to compensate and keep feeding consistent.

      Can I use coco nutrients in hydroponic systems?

      Yes. Most bases in this range are built for soilless growing and run cleanly in coco, perlite blends and hydro setups — check each product page for system suitability.

      What is the difference between 1-part, 2-part and 3-part base nutrients?

      A 1-part is a single bottle for simplicity, a 2-part (A&B) separates elements for stability and control, and a 3-part splits grow, bloom and micro for maximum fine-tuning.
