How do you cultivate a portobello mushroom?

[Edit]

The same way you cultivate most mushrooms. You get spawn or spores. Usually you can inoculate mason jars filled with wild bird seed or rye seeds. The jars must be sanitized with a pressure cooker. Then you inoculate when they cool. The mycilum will begin to grow in jars. when jars is fully colonized you want to spawn it to straw or horse poo. Horse poo is your best bet for portobello. You can use compost also. or a mix of horse poo vermiculite coco coir. YOu have many options. Then u must induce fruiting conditions by dropping temperature and introducing a light source to trigger fruiting. Then maintain the humidity. The shroomery is a great online forum to answer many questions .
