These kits are for serious mushroom lovers. This kit will produce a large amount of edible Oyster Mushrooms and have up-to 4 crops. We want to bring this growing experience to your home with our Gourmet Mushroom Straw Log Kit. It is easy to grow in any position of your choice, and in as little as 21 days you could be harvesting your very own organically homegrown Oyster Mushrooms.
