Magnesium Sulfate/Epsom Salts - 8 oz bottle (STEM Garden Nutrients)

Magnesium Sulfate, aka Epsom Salts, is used in the STEM Garden to give plants sulfur. This is an important addition that isn't present in the 1 KG Bag of STEM Garden nutrients because it tends to bind those ingredients and not dissolve afterwards. A pinch of Magnesium Sulfate goes a long way, making 8 ounces last approx. 8 months.  We recommend nutrients are stored in the locked storage space below the farm.

Take care when handling nutrient solutions. Keep out of reach of children and avoid contact with skin and eyes.

Store in a cool, dry place.
