THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are using a natural chelator because your heavy watering schedule is leaching nutrients out of the medium.
  • You are adding humic acid because your soil based plants show signs of nutrient lockout despite regular feeding.

  • We suggest this for soil growers who find their heavy base nutrients are not fully absorbing as expected
  • Liquid humic acid is much easier to dose accurately than powders which often clump or settle at the bottom of a tank
  • The CFIA registration gives us confidence to recommend this to facilities that require strict quality documentation

  • Soil growers say they notice a visible difference in stalk thickness after adding this to their vegetative stage
  • Users tell us that combining this with fungal inoculants makes the root systems much denser and more resilient

GreenPlanet Nutrients GPH Uptake Humic Acid

0 – 0 – 1 Humic acid supplement designed to promote elite nutrient uptake and retention in soil-based gardens.

Enhance the biological potential of your medium with GreenPlanet Nutrients GPH Uptake. This liquid humic acid supplement is a powerhouse for soil and soilless growers, working perfectly alongside base nutrients like Medi One to significantly improve the availability of nutrients that often become "locked" in the root zone. By acting as a natural chelator, GPH Uptake ensures that your plants can easily absorb essential minerals, leading to more vigorous growth and a more resilient garden from start to finish.

GPH Uptake doesn't just feed the plant; it improves the environment the plant lives in. By increasing the soil's ability to hold onto nutrients, it prevents leaching and ensures food is available exactly when the plant needs it. Furthermore, it encourages the colonization of beneficial mycorrhizal fungi, expanding the root system's reach and efficiency. CFIA Registered No: 2021902A.

Features

🧲
Advanced Chelation

📦
Nutrient Retention

Improves the "holding capacity" of your soil, ensuring nutrients stay in the medium rather than washing away during watering.

🦠
Fungal Support

Promotes the colonization of mycorrhizal fungi in the rhizosphere, maximizing the plant's ability to access deep-seated nutrients.

🌳
Structural Vigor

Boosts the plant’s ability to produce thick stalks and lush green growth during the vegetative stage, especially when paired with Vitathrive.

FAQ

Can I use GPH Uptake in a hydroponic system?+

GPH Uptake is specifically formulated for soil and soilless mediums. For hydroponic applications, GreenPlanet Nutrients recommends using GPF Uptake (Fulvic Acid), which is better suited for liquid-only environments.

How does GPH Uptake prevent nutrient leaching?+

Humic acid has a high Cation Exchange Capacity (CEC). It acts like a magnet, binding to nutrient ions and holding them in the soil so they aren't washed away by water before the plant can use them.

Does GPH Uptake help with nutrient lockout?+

Yes. By chelating minerals, GPH Uptake keeps nutrients in a water-soluble form that is easily absorbed, helping to prevent the chemical reactions in soil that lead to nutrient lockout.

Should I use GPH Uptake in both Veg and Bloom?+

Absolutely. It benefits the plant during its entire life cycle by supporting structural growth in the vegetative stage and maximizing yield with Massive Bloom Formulation and boosting resin production during the flowering stage.

Will this product affect my pH levels?+

Humic acid is relatively stable, but adding any supplement can slightly shift pH. It is always best to check and adjust your pH levels after mixing all your nutrients and supplements into your water.
