General Hydroponics Flora Gro

FloraGro ® by General Hydroponics: The Foundation for Vigorous Plant Growth

FloraGro® is one of the three essential components of the renowned FloraSeries® by General Hydroponics—a nutrient system that has been trusted by growers around the world for decades. Designed specifically for the vegetative stage of plant development, FloraGro® delivers key nutrients that encourage the growth of strong roots, robust stems, and lush green foliage. It plays a critical role in setting the stage for healthy, vibrant flowering and fruiting down the line.

Optimized for Vegetative Growth

FloraGro® features a carefully balanced nutrient profile, with an N-P-K ratio of 2-1-6. This formulation is high in nitrogen, which fuels the production of leafy growth, while also delivering potassium to support overall plant structure and resilience. The inclusion of essential secondary nutrients like magnesium and sulfur ensures that plants receive a well-rounded blend of elements required for optimal growth.

By focusing on the needs of plants during their most dynamic phase of development, FloraGro® helps build a strong foundation, enabling them to better absorb nutrients and thrive throughout their life cycle.

A Core Part of the FloraSeries® System

FloraGro® is designed to work in tandem with two other products in the FloraSeries®: FloraMicro® and FloraBloom®. These three solutions form a customizable feeding system that evolves with your plants. During early growth, FloraGro® is used in higher proportions, while the blend shifts to include more FloraBloom® during flowering. FloraMicro® provides essential micronutrients and acts as the base of the trio, delivering trace minerals and buffering agents that stabilize the solution.

This modular approach gives growers the ability to fine-tune their feeding regimen according to the specific needs of each stage in the plant’s lifecycle, ensuring consistent, high-quality results.

Versatile Across Growing Methods

One of the key advantages of FloraGro® is its compatibility with a wide range of growing environments. Whether you're cultivating in hydroponics, soil, coco coir, or soilless mixes, FloraGro® can be seamlessly integrated into your nutrient schedule. Its solubility and stability make it ideal for recirculating systems, drip irrigation, and manual feeding alike.

FloraGro® is also suitable for both home growers and large-scale commercial operations. The product is manufactured to high quality-control standards, with every batch tested for purity, consistency, and performance in General Hydroponics’ state-of-the-art labs.

Flexible Application

Growers can apply FloraGro® in multiple ways, depending on their setup and goals:

• Hydroponic Systems: FloraGro® dissolves easily in water and provides a direct nutrient feed to plant roots in hydroponic and aeroponic systems.

• Soil and Soil-less Mixes: When used in soil, FloraGro® acts as a liquid fertilizer, delivering precise nutrition without the guesswork.

• Foliar Spray (Optional): In specific cases, a diluted solution can be used as a foliar feed to rapidly address nutrient deficiencies or to stimulate growth.

Always refer to feeding charts and monitor pH and EC levels to ensure optimal uptake.
