Fresh, contam free and perfect innoculation size.

Thus far all of the 5 grain bags and jars I have purchased from MWGK have all been viable, healthy spawn vessels and have colonized without contamination. Delivery is always fast and pricing is always competitive.

Grains held up well. Definitely pasteurized or sterilized properly. Would Buy again.

I love these... I seen signs of growth after 4 days on both bags.. I received them a week after ordering them I will definitely be a returning customer and I would recommend this to everyone.. I've tried 3 different places an these are by far the best.!!!

Item as advertised, promptly delivered and repeat customer.
