Zero-Nitrogen Calcium Support for Late Bloom

During late bloom, plants still require calcium and micronutrients to maintain structure, movement and overall plant function. However, adding extra nitrogen too late in the cycle may not always be desirable. GreenPlanet Horti Late Cal solves this by providing calcium and micronutrient support without adding nitrogen.

This makes it a strong choice for growers who want to support the final flowering phase while keeping the feeding program focused on late bloom development.

The GreenPlanet HORTI line is built for efficient, soluble and scalable plant nutrition. Horti Late Cal is intended for use as part of the HORTI Feeding Program, especially during late bloom when paired with bloom-stage nutrients such as Horti Late Bloom.

Its dry, soluble format makes it suitable for growers using reservoirs, stock tanks, injectors and automated dosing systems where clean mixing and consistency are important.
