You can buy mushroom spawn at many garden stores or online. To grow organic mushrooms, you may have better luck shopping at online shops that specialize in organic mushroom spawn.
If you do not have trees on your property that you can take wood from, buy logs from sawmills or home improvement stores.
If you do not drink coffee or do not drink enough to collect the grounds, go to a local coffee shop that sells organic coffee and ask if they would be willing to give you the grounds or sell them.
If you do not have enough grounds and spawn to fill the bucket, drill a few holes into the side of the bucket about 1 inch (2. 5 cm) above the surface of the grounds and spawn.
