New member from Buenos Aires. Im new with mushroom culture as well. Right now I have Oyster and Psilocybe culture going on.
I have a specific question about gaseous exchange in the colonization of grain spawn. Is it totaly necessary to make opening to the flasks where I have the inoculated grain? Because I couldnt find the materials to make the filter. So I just left small holes on the aluminium paper with the size of the srynge needle. Should I cover the holes with tape to avoid contamination, or I just leave it like it is?
Hope my english is understandable enough. Thanks!
