H&G MgO 8%
H&G MgO 8 % Magnesium is a highly concentrated magnesium supplement designed to prevent and correct magnesium deficiencies at any stage of plant growth. Magnesium is an essential secondary nutrient, central to chlorophyll synthesis and a key activator for over 300 plant enzymes involved in growth, metabolism, and nutrient transport. Without adequate magnesium, plants quickly exhibit interveinal chlorosis; yellowing between the veins, leading to reduced photosynthesis, slower growth, and diminished yields.
This premium formulation delivers magnesium in a highly available form, ensuring rapid uptake and utilisation by plants even under challenging conditions such as fast growth cycles, high-intensity lighting, or suboptimal water quality. By maintaining adequate magnesium levels, MgO 8 % supports deep green foliage, maximises photosynthetic efficiency, and strengthens plant tissue, resulting in healthier, more productive crops.
MgO 8 % Magnesium is fully compatible with all nutrient programs and growing systems, including hydroponics, coco, and soil. It can be used as a preventative measure to maintain optimum nutrient balance or as a corrective feed when deficiency symptoms appear.
Maintain vibrant foliage and optimal plant health with a fast-acting magnesium boost.
