Blue Oyster Mushroom Grow Kit Fruiting Block

Fresh, fast-growing, restaurant-quality mushrooms at home.

Our Blue Oyster is one of the easiest and most rewarding mushrooms to grow. If you’re new to growing, this is the perfect first kit. And if you’re a seasoned fungi lover, you already know how versatile, meaty and reliable Blue Oysters are.

Our kits arrive fully colonised and ready to grow, so you can harvest your own fresh mushrooms in as little as 10–14 days. No complicated setup, no special equipment — just cut, spray, and watch them bloom.

Remove kit from the shipping box as soon as possible. Fruiting blocks should be used within 1 week of receipt. If you don't plan to use immediately, you can refrigerate your block for up to 6 months.
