Crafted to provide balanced and complete nutrition during the vegetative stage, this formula promotes strong, lush growth by delivering all the essential macro and micronutrients your plants need to thrive.

Why Use DutchPro Coco/Hydro Grow A&B?

During the early and middle stages of a plant's life, strong vegetative growth is vital to support future flowering. DutchPro Grow A&B delivers everything your plants need to build a robust structure and healthy root system while correcting and preventing common deficiencies—especially in areas with hard water. The specialised formulation accounts for the elevated calcium and bicarbonates in hard water, helping to stabilise pH and prevent nutrient lockout.

Benefits of DutchPro Coco/Hydro Grow A&B Hard Water

Optimised for Hard Water Conditions
This formula is specifically developed for regions with high water hardness, helping prevent calcium imbalances and salt build-up that can harm plant health.

Complete Macro and Micronutrient Profile
Provides a full spectrum of essential nutrients—Nitrogen (N), Phosphorus (P), Potassium (K), Magnesium (Mg), Calcium (Ca), and trace elements—to promote thick stems, strong roots, and lush green leaves.

Supports Explosive Vegetative Growth
By encouraging the rapid development of foliage and roots, Grow A&B lays the foundation for heavy yields later in the flowering stage. Expect faster growth and more resilient plants.

Balanced Two-Part Formula for Precision Feeding
Separated into Part A and Part B to prevent nutrient interactions in the bottle, DutchPro ensures maximum stability and availability when mixed. Always add A and B separately to your water.

Easy to Use in Any Coco or Hydroponic Setup

DutchPro Coco/Hydro Grow A&B is suitable for all coco-based or hydroponic systems, including drip, NFT, DWC, and run-to-waste setups. Simply mix equal parts of Grow A and Grow B into your reservoir, following the dosage guidelines appropriate for your plant’s size and development stage.

Typical Dosage
Use 1–3 ml/L of Grow A and the same of Grow B, depending on the plant’s needs and target EC. Always check the pH and EC after mixing and adjust as necessary.
