Core Base Nutrient for 3-Part Feeding Systems

Emerald Harvest Micro is the foundation of the Emerald Harvest 3-part nutrient system, delivering a full spectrum of essential macro and micronutrients to support strong, healthy plant growth from start to finish.

Used alongside Grow and Bloom, Micro completes the feeding programme by supplying key elements that drive plant structure, metabolism and nutrient uptake throughout the entire lifecycle.

Key Benefits

• Provides essential macro & micronutrients for full plant development
• High nitrogen content to support strong vegetative growth
• Includes calcium for stronger cell structure
• Delivers key trace elements like iron, zinc and manganese
• Forms the foundation of the 3-part system
• Suitable for hydro, coco and soil

Why You Need It

Micro is the backbone of the Emerald Harvest 3-part system. Without it, your plants miss out on critical micronutrients that support everything from chlorophyll production to nutrient transport.

It also delivers a higher level of nitrogen, making it especially important during vegetative growth when plants are building structure, leaves and overall size.

How to Use

Use Micro alongside Grow and Bloom as part of a complete feeding programme. The ratio changes depending on whether your plants are in veg or flower.

• Always add Micro first to your water
• Mix thoroughly before adding Grow or Bloom
• Adjust ratios depending on growth stage
