10# Crater Lake Cal-Mag

(1 customer review)


Categories: , ,


Derived from basalt and citric acid, with 1% molasses to feed microbes, Crater Lake Cal-Mag uses strictly natural ingredients to provide two of the most plant essential nutrients that aren’t N-P-K.! Great for tree’s and shrubs, gardens and field crops, potted plants, and even to buffer media for plants grown in coco. Ditch the salt for better results.
