Cal Green

Cal Green by Metrop Supplies Cannabis Plants with Calcium as they are Often Lacking this Element

Cal Green by Metrop is a product used to give your plants easy-to-absorb calcium in order to avoid nutrient deficiencies in hydroponic systems and soft water.

Calcium is a mineral that cannabis plants need, especially during the flowering period. It’s used to create their cell walls and keep your plants sturdy and strong. This product also contains magnesium, which tends to be the cause of nutrient deficiency in many plants during the bud fattening period. With CalGreen alongside Metrop’s flowering base (MR2), you’ll be able to give your plants absolutely everything they need for the entire flowering period while using 100% natural ingredients. This product is also perfect for your Auto Critical GB XXL 100% Feminized.
