Epsom salt, the nickname given to magnesium sulfate, is a compound that was discovered in underground springs in the town of Epsom, England. It is a natural and organic source of both magnesium and sulfur. Epsom salts are commonly used in bath salts, exfoliants, muscle relaxers and pain relievers. However, these are different from Epsom salts that are used for gardening, as they contain aromas and perfumes not suitable for plants.

The Importance Of Magnesium in Epsom Salt

Epsom salt is a natural source of magnesium – one of the most important nutrients to a plant’s life, as it encourages its uptake of essential nutrients like nitrogen, phosphorus and potassium. Magnesium is also important for your plant’s development of chlorophyll, the component responsible for your cannabis’ ability to absorb sunlight, which allows photosynthesis to occur by strengthening cell membranes. Overall, a healthy level of magnesium is what’s responsible for the successful and healthy growth of your cannabis plants.

Why Do Plants Need Sulfur?

Sulfur is the essential basis for your plant’s immune system. Sulfur facilitates the production of amino acids, enzymes and vitamins in your plant, all of which aid in the healthy growth of a plant and build up its immune system. In other words, a healthy base of sulfur in your garden will help prevent your plants from getting sick. Sulfur is also essential for your plants to create chlorophyll. Most importantly, it works together with magnesium to secure the plant's uptake of nitrogen, phosphorus and potassium, or NPK – the most essential nutrients to a cannabis plant’s survival.

The Right Time To Incorporate Epsom Salt

You can begin using Epsom salt for cannabis plants within the beginning of each lifecycle, when the plants are just a few inches tall. You should, however, cease using Epsom salts during the first week of flowering, as this can alter the growth of buds. Generally, a good amount of magnesium and sulfur throughout a plant’s life will ensure a high yield.
