Emerald Harvest Nutrients & Plant Supplements
Emerald Harvest is a premium nutrient brand producing a focused lineup of base nutrients and plant supplements designed for performance-focused indoor growing programs. Their product philosophy emphasizes ingredient quality and formula transparency - using pharmaceutical-grade chelates and high-purity mineral salts to produce clean, highly bioavailable nutrients with predictable EC contribution. Emerald Harvest is particularly popular in coco coir and hydroponic growing programs where clean, consistent nutrient behavior in recirculating and drain-to-waste systems matters for precision EC management.
Emerald Harvest Base Nutrients
Emerald Harvest's base nutrient line centers on Grow, Bloom, and Micro (a three-part system structured similarly to General Hydroponics FloraSeries but with higher-purity chelated formulations) and the Root Wizard microbial inoculant designed to establish beneficial rhizosphere biology from transplant. Their Cali-Magic Cal-Mag supplement provides calcium and magnesium in a ratio optimized for the coco coir and high-performance hydroponic programs their base nutrients are designed for. Pair with pH meters and EC meters for precise monitoring when running Emerald Harvest's recommended EC-based feeding schedules.
Emerald Harvest Supplements & Additives
Beyond base nutrients, Emerald Harvest produces a range of performance supplements including Honey Chome (a carbohydrate and amino acid supplement for root zone biology and terpene development support), King Kola (a PK bloom booster for the peak flowering stage), and Sturdy Stalk (a potassium silicate supplement for structural stem strength - functionally equivalent to other potassium silicate silica products). The complete Emerald Harvest lineup is designed to work as an integrated system, with each product formulated around the base nutrient ratios to avoid nutrient antagonism when running the full program.

Emerald Harvest FAQ
How does Emerald Harvest compare to General Hydroponics?
Both are three-part liquid nutrient systems (Grow/Bloom/Micro structure) suitable for hydroponic, coco, and soil growing. Emerald Harvest positions itself at a higher quality tier with pharmaceutical-grade chelated minerals and higher-purity raw materials than standard GH FloraSeries. In practice, both produce excellent results when used correctly with proper EC and pH management. Emerald Harvest tends to be favored by growers running performance-focused programs where nutrient behavior consistency and ingredient quality are priorities; GH FloraSeries is the more cost-effective and more broadly documented option with the largest community knowledge base. Brand choice often comes down to program preference, price sensitivity, and whether the quality premium of Emerald Harvest's formulation is meaningful for your specific growing approach.
What EC should I run with Emerald Harvest nutrients?
Emerald Harvest publishes specific EC targets for each growth stage on their feeding schedule. General ranges: seedlings 0.4-0.8 mS/cm; early vegetative 1.0-1.5 mS/cm; late vegetative 1.5-2.0 mS/cm; early flowering 2.0-2.5 mS/cm; peak flowering 2.5-3.0 mS/cm; late flowering and flush 0.0-0.5 mS/cm. These are starting points - adjust based on plant response and visual health indicators. Use our Nutrient Mixing Calculator to determine exact volumes for any target EC and reservoir size when following Emerald Harvest's feeding schedule.
