Green Planet Horti Cal | 2.3kg Powder Pack | Calcium Magnesium Supplement for Plants

🌿 Green Planet Horti Cal | 2.3kg Powder Pack

Strong plants start with strong foundations. Horti Cal is a high-performance dry fertiliser that delivers a steady supply of nitrogen (14%), calcium (Ca), and magnesium (Mg) across every stage of growth, from seedling right through to harvest.

Calcium and magnesium are two of the most commonly deficient nutrients in both soil and hydroponic grows. Horti Cal keeps those levels dialled in so your plants can focus on what they do best: growing fast, staying healthy, and producing to their full potential.
