Gypsum
is one of the most underappreciated elements in many all-natural gardens, and what it brings
to the table is all good for cannabis especially. Some ancient organic growers from around “The Pygmy
Forest” in Northern California used to rave all the time about gypsum, and how the slow-release sulfur
enhanced natural smells and flavors in the final cannabis buds. Gypsum is calcium and sulfur, and many
people believe, as I used to, that it radically lowers soil pH. The truth is that it will have this effect in soils

works wonders on big clay-packed soils, and aerates them by somehow bringing in fungus to thrive on the
clay minerals. Where fungi are dominant they tend to cause the pH to drop, as most of them prefer a lower
soil pH. The upshot of this is that you should not make the mistake of using gypsum in a soil mix that has
a low pH to start with: the low pH will give the fungi a little too much help and an unfair advantage. If the
fungi get out of hand they will normally take the pH way too low and fry the plants. They seem to have
done that to me in the past on three or four occasions.
I use powdered gypsum and love it for its slow-release sulfur
