THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You're switching to a dry cal-mag because shipping heavy liquid concentrates eats too much of your profit margin.
  • You are upgrading to high-purity minerals because organic fillers in your current mix keep clogging your emitters.
  • You are applying a coco buffer because inconsistent calcium levels are leading to weak stalks and poor development.

  • We tell folks looking at liquid cal-mag to switch to this powder because the shipping savings are massive on big tubs.
  • It mixes into a perfectly clear solution that actually stays suspended instead of settling at the bottom of the tank.
  • The purity is high enough that we have never seen it cloud up a reservoir even when mixing it in cold water.

  • Facilities using injection systems say they stopped worrying about clogged emitters once they swapped to this powder.
  • Users running high-performance reservoirs say the consistent pH levels make their daily maintenance much faster.
  • Growers who switched to this powder say they cut their annual supplement costs by more than half compared to liquids.

GreenPlanet Nutrients Horti Cal

14-0-0 + Calcium (Ca) + Magnesium (Mg)

Horti Cal keeps plants strong throughout the entire growth cycle, serving as a powerful companion to GreenPlanet Nutrients Horti Grow during the vegetative stage. It is formulated to supplement Nitrogen, Calcium, and Magnesium, maintaining healthy plants and encouraging rapid growth and development.

GreenPlanet Nutrients Horti Cal is a specialized, water-soluble mineral supplement designed for the high-performance demands of modern cultivation. By providing a concentrated source of Calcium and Magnesium—offering a dry-powder alternative to the liquid GreenPlanet Nutrients Pro Cal Supplement—Horti Cal prevents common deficiencies and builds the cellular "skeletal system" your plants need to carry heavy yields. This science-based formula ensures your garden remains vibrant and structurally sound from the early vegetative stage through the final weeks of flowering with Horti Late Bloom.

Engineered for professional efficiency, Horti Cal is crafted from 100% chemically compatible, high-purity ingredients. It contains zero organic fillers or contaminants, resulting in a perfectly clear solution that will not clog emitters, stock tanks, or sophisticated injection dosing systems. Whether you are using it to buffer coco coir or to supplement a hydroponic reservoir, Horti Cal delivers the stability and superior uptake rates required for commercial-scale success.

FAQ

When should I use Horti Cal?+

Horti Cal can be used throughout the entire plant life cycle. It is especially important during rapid vegetative growth and the early-to-mid flowering stages alongside GreenPlanet Nutrients Horti Bloom when the demand for Calcium and Magnesium is at its peak.

Is Horti Cal compatible with other nutrient brands?+

Yes. Horti Cal is made from chemically compatible, high-quality ingredients that can be integrated into most feeding programs, including the GreenPlanet Nutrients Dual Fuel 1 & 2 system. Always add and mix supplements thoroughly into the water before adding other concentrated nutrients.

Will this powder clog my drip emitters?+

No. Horti Cal is highly soluble and contains zero sediment or fillers. It is designed specifically to run cleanly through irrigation lines and automated injection systems like Dosatrons.

Why is there Nitrogen in this supplement?+

The 14% Nitrogen in Horti Cal provides a readily available source of energy that supports the rapid development facilitated by the Calcium and Magnesium, ensuring your plants don't stall during growth spurts like those supported by GreenPlanet Nutrients Vitathrive.

Can I use Horti Cal for coco coir buffering?+

Absolutely. Because of its purity and high solubility, Horti Cal is an excellent choice for buffering coco coir to satisfy the medium's initial cation exchange demand for Calcium and Magnesium.
