When you order an MYG upgrade you will not need to cardboard box and dome that usually comes with the individual MYG. You simply utilize the kits grow chamber in place of the missing two items and it will work just as effectively. The MYG upgrade will include 1 pre-sterilized rye grain jar, 1 large bag of shredded wheat straw, 1 large bag of casing soil, 1 casing starter, 1 spray bottle and plastic bag for mixing. You can also double the size of your grow chamber if you need more room by turning one of the chambers upside down and on top of the bottom chamber therefore doubling your fruiting space. It works great! Follow the MYG instructions here:
