General Hydroponics FloraMicro 1 Quart

FloraMicro is part of FloraSeries, the O.G. 3-Part Hydroponic-Based Nutrient System. More than 40 years ago, when the other guys were still in grade school, our scientists were hard at work with a mission: to give growers a consistent and precise way to feed their plants through every growth phase. First formulated in 1976, FloraSeries is the original 3-part hydroponic-based nutrient system consisting of FloraGro, FloraBloom and FloraMicro. Good things really do come in threes.

The O.G. 3-Part Hydroponic-Based Nutrient System
More than 40 years ago, when the other guys were still in grade school, our scientists were hard at work with a mission: to give growers a consistent and precise way to feed their plants through every growth phase. First formulated in 1976, FloraSeries is the original 3-part hydroponic-based nutrient system consisting of FloraGro, FloraBloom and FloraMicro. Good things really do come in threes.

Plant Nutrition for Every Growth Stage
By using different combinations of FloraGro, FloraBloom and FloraMicro, you can help fulfill your plants’ nutrient needs at every stage of growth in all kinds of environments, for happy plants from seed to bloom. Adjust how much and when you use each to create your own personal recipes. Then grow knowing your nutrients are optimized to deliver the primary, secondary and micronutrients that push serious growth and brag-worthy blooms all season long.

Beautifully Balanced for Big Growth
FloraSeries is formulated to help feed the right minerals, in the right ratios, to help plants flourish. Each formula is carefully proportioned for balanced nutrition. Too much or not enough of a particular element in a plant’s diet can lead to deficiencies and toxicities. We work to ensure FloraSeries provides proper balance by batch-testing our products in a state-of-the-art lab with tight quality control.

Advantages 

• Proven legacy as the original system — Part of the O.G. 3-part hydroponic nutrient line since 1976 (over 40+ years of refinement and trust), developed when competitors were just emerging—delivering consistent, precise feeding across every growth phase.
• Essential foundation & "building block" — Serves as the core of the entire FloraSeries; provides critical nitrogen (5%), potassium (1%), calcium (typically 5% in standard formula), plus a full spectrum of chelated micronutrients and trace elements (e.g., iron, manganese, boron, zinc, copper, molybdenum) that form the base for a complete hydroponic diet.
• Comprehensive micronutrient delivery — Supplies readily available, chelated trace minerals essential for enzyme function, chlorophyll production, and preventing hidden deficiencies—ensuring plants thrive even in fast-growing or demanding conditions.
• Supports all growth stages — Always included in mixes; pairs with FloraGro for vegetative/structural growth (extra N & K) and FloraBloom for flowering/fruiting (P, K, Mg, S), allowing precise customization to match any plant's changing needs from seedlings to harvest.
• Prevents imbalances & deficiencies — Delivers balanced primary, secondary, and micronutrients in proper ratios, reducing risks of excesses, lockouts, or shortages—promotes vigorous, healthy plants with strong roots, foliage, and overall resilience.
• Versatile & adaptable — Works in hydroponics, soil, coco, soilless media, and any environment; easy to adjust ratios via the "building block" system for personalized recipes tailored to specific crops, lighting, or conditions.
• Fully soluble & reliable performance — Keeps nutrients water-soluble and immediately plant-available; batch-tested with tight quality control for consistency—trusted for "brag-worthy" results like enhanced growth, larger yields, and nutrient-dense crops.
• Simple integration — Mix FloraMicro first (standard protocol), then add others—prevents nutrient lockout and makes the system user-friendly for beginners to pros. 

Directions for Use

As Nutrient Additive: Shake well. Add to nutrient solution at the rate of 1 teaspoon per 5 gallons water (.25 ml per liter). Keep solution aerated. Renew with each nutrient change.

As a Foliar Spray: Add 1-2 teaspoons per gallon water (1-2 ml per liter). Spray foliage lightly, particularly the bottoms of leaves. Use weekly in addition to your regular fertilizers.

For Use With

Plants: Hemp, Herbs, Flowers, Fruits, Vegetables, and High-Value Crops

Media: Coco, In-Ground Soil, Peat Lite Mix, Potting Mix
