Green House Feeding Calcium is an EDTA-chelated calcium supplement that prevents and corrects symptoms caused by calcium deficiency or unbalanced uptake. The chelate is very stable and does not react with other nutrients.

The product is especially suited to use with soft water (reverse osmosis, rainwater) and substrates low in calcium. The chelated form can be mixed with fertilisers containing sulphate and phosphate without precipitation.

Calcium is ideal for soil growing (peat-based media). For hydroponic systems (coco, rockwool, hydro), CalMag is recommended.
