Italspawn has introduced new spawn bags. Instead of 2 filters, the bags have 4 filters now. The main benefits are increased oxygen exchange for the spawn to breath better. Therefore there is an more faster and optimal colonization inside the bags. Early testing in the new test facility has shown spawn being more active straight out of the bag and shorten the incubation time in the compost with 1 day. From now on all bags come with the new 4 filters.
