Hesi CalMag 1L

FOR PERFECT MINERAL BALANCE

Plants need a balanced supply of minerals to grow strong and healthy. When using soft, demineralised, or reverse osmosis (RO) water, important minerals such as calcium and magnesium are often missing. Hesi CalMag replenishes these nutrients and ensures that plants receive the mineral balance they need for stable growth. 

Calcium strengthens the plant’s cell walls and supports a solid plant structure, as well as transmissions of important signals. Magnesium is an essential component of chlorophyll and therefore vital for photosynthesis. Together they help plants absorb nutrients efficiently and maintain healthy, deep green leaves. Hesi CalMag can be used in soil, hydroponics and coco substrates and is especially useful in modern cultivation systems and LED growing environments, where plants may require additional calcium and magnesium. 

It's Hesi's mineral balance in a bottle! 

Hesi CalMag buffers soft water and supports healthy plant development in all growth stages – from cuttings to flowering.
