PRODUCT DETAILS
RADONGROW Extra CAL-MAG
Premium Calcium • Magnesium • Silicon Supplement
Available Sizes: 500 ml | 5 L
Product Overview
RADONGROW Extra CAL-MAG is a premium calcium, magnesium, and silicon supplement specially developed to support vigorous plant growth, stronger root systems, and healthier crop development across all growing stages.
Fast-growing plants have a high demand for calcium and magnesium. Water sources such as Reverse Osmosis (RO), purified water, rainwater, or naturally soft water often contain insufficient levels of these essential elements. RADONGROW Extra CAL-MAG helps replenish these nutrients, supporting healthy cell development, chlorophyll production, photosynthesis, and overall plant vitality.
Our advanced formulation also contains bioavailable silicon and potassium to strengthen plant structure, improve stem strength, enhance resistance to environmental stress, and support optimal nutrient utilization.
The highly soluble formula mixes easily with nutrient solutions and is suitable for hydroponics, coco coir, rockwool, soil, peat-based media, and all irrigation systems without leaving unwanted residues.
Whether you're growing leafy greens, vegetables, herbs, flowers, fruits, or commercial crops, RADONGROW Extra CAL-MAG provides reliable secondary nutrient support throughout the entire growth cycle.
Why Choose RADONGROW Extra CAL-MAG?
Advanced Calcium & Magnesium Support — Provides readily available calcium and magnesium to support rapid growth and healthy plant development.
Silicon Enhanced Formula — Fortified with bioavailable silicon to help strengthen cell walls, improve stem rigidity, and increase resistance to environmental stress.
Promotes Healthy Root Development — Supports vigorous root growth, improving water and nutrient absorption throughout the plant's life cycle.
Optimizes Nutrient Uptake — Maintaining adequate calcium and magnesium levels helps maximize the availability and utilization of essential nutrients.
Supports Chlorophyll Production — Magnesium is a critical component of chlorophyll, helping plants maintain healthy green foliage and efficient photosynthesis.
Prevents Common Deficiency Symptoms — Regular use helps reduce the occurrence of calcium and magnesium deficiencies that may lead to weak growth, leaf chlorosis, tip burn, blossom-end rot, or poor plant performance.
Highly Soluble Formula — Mixes quickly into nutrient solutions without clogging drip emitters, irrigation systems, or hydroponic equipment.
Suitable for All Water Types — Ideal for Reverse Osmosis (RO) water, purified water, soft water, rainwater, and regular tap water when additional calcium and magnesium supplementation is required.
