Description
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.

I like it to replace cal mag in my soil, works really well with my LED lights.
