Mushroomsupplies.com pre made sterilized 5 pound mushroom growing media for dung loving mushrooms. Has filter patch and injection site patch. Made with millet and a mixture of stuff that makes them flush like mad and made for direct liquid inoculation for quick and easy colonization. Literally all you have to do is squirt the syringe with the liquid culture into the bag and set it where it's 70-80 degrees and wait! These are usually good for three flushes. These are just the growing medium - there are no mushroom cultures included. $40 trade each you pay the shipping. Want one bag I can poke it in a flat rate padded envelope for $10, want more HMU and i can figure out the shipping.
