The Mushroom Kit That's Impossible to Mess Up
Most people have never grown mushrooms before.
They're worried they'll do it wrong. Kill it somehow. Waste $27 on a box that never fruits.
That's why we created the Blue Oyster ShroomBag.
It's the most forgiving mushroom we grow. Tolerates temperature swings. Fruits even if you forget to mist for a day. Produces reliably every single time.
This is your starter mushroom. Your gateway. Your guarantee you'll succeed.
Blue Oyster grows in beautiful gray-blue clusters with hearty, meaty caps. The flavor is mild and savory—deep umami that works in literally everything. Stir-fries, soups, pastas, grilled, roasted, sautéed. It rips apart clean for cooking. No knife needed.
What You'll Harvest:
- First flush: 10-14 oz (7-10 days)
- Second flush: 6-10 oz (flip the bag, repeat)
- Third flush: 4-6 oz (highly likely with this variety)
- Total: 20-30 oz over 4-6 weeks
Why Blue Oyster First:
- Grows fast (7-10 days to first harvest)
- Forgiving temperature range (60-75°F—works in most homes)
- Mild flavor (if you're new to gourmet mushrooms, start here)
- Reliable multiple flushes (maximizes your $27)
- Beginner-approved (we've never seen anyone fail with this one)
100% guaranteed to fruit or we replace it free.
