These spawn starter culture is prepared in sterile condition. Comes in a jar with varying weight of your choosing. This can be added to the substrate of your choosing. All you have to do is prepare you substrate and add the spawn to the mix. It is recommended that you add one part spawn to 10 parts of substrate to allow quick and easy colonisation of the substrate. However, lower ratios have been used but these give suboptimal results and is prone to contamination.
Due to biosecurity and pest control laws, we do not ship to WA nor TAS.
