Gypsum is added to mushroom growing substrates providing calcium and sulfur.

Gypsum also helps spawn substrate break-up making it easier to mix when needed.

Use at a 2-5% ratio for best results. This usage rate is best measured off the dry-weight of the substrate.

Can be beneficial for all mushroom kits and beds.

Gypsum is generally PH-7 meaning it is netural and does not affect the substrate's PH much.

TESTIMONIALS

"Excellent service!

Sporeshift have consistently got the best service of any online provider I have used. From the time of order to delivery the communication is great. I frequently wonder why other businesses can't to it the way they do. Excellence in action. And no, I am not their mother ... just a satisfied customer and mushroom lover. :)"

"Loving watching the magic of the growth cycle and increasing our own food security and self reliance in the process! My kindy wildlings are loving the video updates of how they're going each day! Excited to extend my varieties next. Oysters were definitely a winner on a magenta spreen, thyme, white sauce and olive pizza tonight!!"
