Green House Feeding Calcium, chelated calcium

Green House Feeding Calcium is an EDTA-chelated calcium supplement. It is intended to make up for insufficient calcium in the water and substrate.

When is it needed?

Assess this based on water quality and the base nutrient program. With hard water or calcium-rich soil, the manufacturer recommends not adding Calcium.

Dosage

The recommended range is 0.5 to 1 g per liter of water, with the amount reduced according to the calcium already present. This is a guideline for when a need has been established, not a mandatory additive for every watering.

Calcium or CalMag?

Green House Feeding recommends Calcium for soil growing with peat-based mixes, and CalMag for coco, rockwool, and hydroponics. CalMag also supplies magnesium and nitrogen, so the two products are not interchangeable at the same dose. Do not combine them as two calcium supplements.
