This product is Hydrated Lime (builder's lime) for use in pasteurisation of mushroom substrate. It is NOT "pickling lime" and is not fit for consumption or as an ingredient in food products. Please read our safety warning below for handling Hydrated Lime.


This powder is used to increase the pH of your substrates during pasteurisation. Only 1g is needed for every litre of water. Not to worry if more than 1g is added - this will not affect the process as it will simply not dissolve and remain as sediment in the water.

Our hydrated lime comes in a resealable pouch for easy use and to keep dry when not in use.

SAFETY WARNING: Please use in a well-ventilated environment and wear gloves, a mask and goggles or glasses when handling as this is corrosive to the skin. Not to be used as pickling lime. This is builder's lime.

Weight: 200g
