CalMag 2.0

B.A.C. (Biological Advanced Cultivation) CalMag 2.0 is the latest generation calcium and magnesium supplement from B.A.C., a Dutch professional cannabis nutrient brand. The '2.0' version designation indicates an improved formulation over the original CalMag — likely featuring better bioavailability, enhanced trace element coverage, or improved compatibility with B.A.C.'s nutrient system.

Apply throughout vegetative growth and early flowering when calcium and magnesium demand is highest. Compatible with B.A.C.'s complete product range. Made by B.A.C. Fertilizers, Netherlands.
