Oyster mushrooms are the easiest to grow, and a great choice for novices. To get started, buy them online, in a home gardening store, or in a homebrew supply store in the form of "spawn": spores or root-like mycelium stored in sawdust, grain, or agar. You can buy the spawn alone or as part of a complete oyster mushroom kit. Any oyster mushroom variety will work, but blue grey oysters and pink oysters are especially easy and quick to grow.Growing outdoors? "Plug spawn" is a slow but even easier alternative. Just drill holes in the side of a newly fallen hardwood log (avoid "softwood" or pine because they will inhibit the growth of fungus), insert the plugs, and wait for damp weather. If your kit came with a large bag of straw, that's a ready-to-go substrate, or material that provides nutrients and a place to grow. If you only have a small container of mushroom spawn, you'll need to make your own substrate, and heat it so only beneficial microbes can grow. Here are two ways to make a substrate: Cardboard:Best for spawn in sawdust1. Cut corrugated cardboard into pieces of equal size, a few inches square.2. Put the cardboard in a bucket and weigh it down with a heavy object.3. Add boiling water to submerge the cardboard.4. Cover with lid and let cool for eight hours.5. Wash hands with antibacterial soap.6. Squeeze out as much water as you can. Straw:Best for spawn in grain1. Choose a cereal straw such as wheat or rye.2. Cut into 34 inch lengths (7.510cm) using a shredder or a weed whacker in a garbage can.3. Tie in a pillowcase or nylon mesh laundry bag.Submerge in pot of water on stovetop.4. Heat at 160170F (7075C) for one hour.5. Drain well and let cool to below 80F (27C). Now the spawn is ready to colonize the substrate with mycelium. Most strains do this best at temperatures between 60 and 75F (1624C). Even small variations in temperature can decrease mushroom yield or encourage contamination, so try to find a room that stays at this temperature 24 hours a day. Mycelium can grow at any light level except direct sunlight. Some growers find they get better results with low light on a daylight cycle (real or simulated). However, if you are using straw, too much light can cause grain to sprout and interfere with mushroom growth. The ideal temperature depends on the strain. If your spawn came with instructions for a growing environment, follow them.
