Gypsum
R45.00
Powdered gypsum is used to increase the pH in mushroom growing substrates such as coco choir, sawdust, coffee grounds and straw. It is a yield enhancer as it supplies minerals and trace elements to the mycelium.
It is also used when preparing grain spawn to stop the grain from clumping together.
Gypsum should be mixed at a rate of 2.5% of the dry weight of the bulk substrate and 1 tablespoon per litre of grain spawn.

Bran Flour
Wheat bran flour is commonly used as an ingredient in substrates of wood-loving mushroom species. It is very nutritious and needs to be sterilised when added to fruiting blocks.
Generally bran is added as 30% of the total fruiting block.

Popcorn is used for grain spawn, easy to prepare and good grain to begin with.
Hydrated Lime
Cold Water Lime Pasteurization, is a cheap and effective low-tech way to prepare substrates for growing mushrooms.
This type of substrate treatment is easy for most people to do at home.
It’s even used by some small-scale commercial mushroom growing operations that want a low-tech, cheap and effective way to pasteurize straw.
The overall process is very similar to growing mushrooms on straw with heat pasteurization, the only difference is to replace heat with lime.
This process is mainly used to treat straw for growing Oyster mushrooms.
Use 20 grams of hydrated lime per 10 liter s of water.
Simply add the appropriate amount of lime to cold water, mix and add your straw. Leave the straw to soak for 24 hours and it is ready to be drained and inoculated.
