General Hydroponics FloraGro 2.5 Gallon

FloraGro 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 & reliability — The original 3-part hydroponic system since 1976 (over 40+ years of refinement), trusted by generations of growers for consistent, precise results when others were just starting out.
• Targeted bloom & fruit booster — Delivers high phosphorus (P), potassium (K), magnesium (Mg), and sulfur (S) specifically for the flowering, fruiting, and reproductive stages, stimulating prolific blossoms, larger fruits, better seed/tuber formation, and enhanced ripening.
• Customizable for every stage — Combine flexibly with FloraBloom and FloraMicro to create personalized recipes tailored to your plants' exact needs—adjust ratios for seedlings, veg, transition, or full bloom—ensuring optimized nutrition from seed to harvest.
• Balanced, deficiency-resistant nutrition — Provides properly proportioned primary, secondary, and micronutrients to prevent imbalances, deficiencies, or toxicities; promotes vibrant, healthy growth with "brag-worthy" blooms and serious yields all season.
• Versatile across setups — Works in all environments (hydroponics, soil, coco, soilless) and for diverse plants—ideal for hydro applications, potted plants, vegetables, flowers, fruits, and more.
• Fully soluble & plant-available — Keeps nutrients completely water-soluble and immediately accessible, supporting fast uptake in hydro systems without lockout when mixed properly (always add FloraMicro first!).
• Quality-controlled performance — Batch-tested in state-of-the-art labs with tight QC for consistent mineral ratios and superior results—enhances flavor, aroma, essential oils, vibrancy, and overall crop quality.
• Simple yet powerful system — Part of an easy-to-use "building block" trio that gives growers precise control without complexity—mix, monitor pH/EC, and adjust as needed for happy, high-performing plants. 

Directions for Use

• Combine FloraGro with FloraMicro to provide a specialized nutrient for rapidly growing plants during the flowering and fruiting phase.
• Mix precise formulas for specific applications by combining FloraMicro, FloraGro plus FloraBloom. This "building block" system enables you to create tailor-made nutrient mixes for many different types of plants and each phase of growth: seedling, cutting, structural, flowering and fruiting.
• Our combination of primary and secondary nutrients keep nutrients fully water soluble and available to plants.
• Ideal for all hydroponic applications and as a nutrient supplement for potted plants.

For Best Results

• Use a conductivity or ppm meter to monitor water quality and control nutrient strength. Drain, discard and replace nutrient every week or two to prevent nutrient imbalance.
• Maintain nutrient pH between 5.5 and 6.5. Adjustment may be necessary since water quality and pH vary both regionally and seasonally.
• Refer to the Basic Applications Table for general mixing recommendations. Please measure accurately. Reduce nutrient strength if plants show signs of stress or if growing in very bright, hot or dry environments.
• SHAKE WELL BEFORE MIXING. Always add FloraMicro to fresh water first and stir well, then add FloraGro and/or FloraBloom. Never combine FloraMicro with FloraGro or FloraBloom in undiluted form; doing so may cause nutrient lockout making some minerals unavailable.
