Fulvic and Humic Acid Canada: Unlock Nature’s Nutrient Booster

Fulvic and humic acids are naturally occurring components of humic substances derived from decomposed organic matter. Both help improve nutrient availability and support plant health, but their different properties make them better suited to different growing systems. 

GreenPlanet Nutrients offers two specialized supplements: GPF Uptake, a fulvic acid formula designed for hydroponic systems, and GPH Uptake, a humic acid formula developed for soil and soilless applications.

Fulvic and humic acids are naturally occurring compounds found within humic substances, which are formed through the decomposition of organic matter. Both play an important role in improving nutrient availability and supporting overall plant health, but their unique properties make them better suited to different growing environments.

GreenPlanet Nutrients USA offers two specialized supplements designed for different cultivation methods: GPF Uptake, a fulvic acid formula ideal for hydroponic systems, and GPH Uptake, a humic acid formula developed for soil and soilless growing applications.

Why Fulvic and Humic Acids Matter to Canadian Growers

Plants can only use nutrients that are available for absorption. Fulvic and humic acids help improve nutrient availability by chelating minerals and supporting their movement through the growing environment.

Fulvic acid contains smaller, highly water-soluble molecules that help transport nutrients more efficiently to plants. Humic acid contains larger molecules that help retain nutrients and support a healthy, active root zone in soil and soilless growing mediums.

For growers across the USA using different crops, climates, and growing systems, selecting the right supplement can help plants maximize their nutrient uptake and get more from their feeding program.

GPF Uptake: Fulvic Acid for Hydroponic Systems

GPF Uptake is a low molecular weight, water-soluble fulvic acid supplement designed specifically for hydroponic growing systems.

Its chelating properties help improve nutrient mobility, making both macro and micronutrients more available for plant uptake. Once absorbed, these nutrients can move more efficiently throughout the plant, supporting healthy growth, stronger structure, and overall plant vitality.

GPF Uptake can be used throughout the entire growing cycle. Add it to your regular nutrient solution at a rate of 5 ml/L during watering or feeding.

GPH Uptake: Humic Acid for Soil and Soilless Applications

GPH Uptake is a liquid humic acid supplement formulated for plants grown in soil and soilless media.

Humic acid helps retain nutrients within the growing medium, keeping them available in the root zone for when plants need them. It also supports nutrient exchange and helps maintain a healthy environment around the roots.

GPH Uptake can be used throughout the entire growing cycle. Add it to your regular watering or nutrient solution at a rate of 5 ml/L.

Foliar Application

Both GPF Uptake and GPH Uptake can also be applied as foliar sprays, allowing plants to absorb nutrients directly through their leaves.

Foliar applications should be applied early in the morning or later in the evening. Avoid spraying under direct sunlight or active grow lights, as excess moisture combined with intense light can cause leaf damage.

Apply at the recommended rate and lightly mist the foliage without fully saturating the plant.

Product	Primary Application	Recommended Rate	Main Benefit
GPF Uptake	Hydroponic systems	5 ml/L	Supports nutrient mobility and uptake
GPH Uptake	Soil and soilless media	5 ml/L	Supports nutrient retention and root-zone health
