Button mushrooms—also known as white mushrooms, champignons, or Agaricus bisporus—are the most commonly consumed mushrooms worldwide. They’re mild in flavor, incredibly versatile, and surprisingly easy to grow at home. Whether you’re a curious beginner, a DIY-loving gardener, or a parent looking for a fun educational project, a button mushroom growing kit is a great place to start.
In this guide, we’ve rounded up the best button mushroom growing kits for 2025 based on ease of use, yield, price, and overall customer satisfaction. We’ve also included important tips to help you succeed from your first flush to your last.
Why Grow Button Mushrooms at Home?
- Freshness: Store-bought mushrooms often sit in transit for days. Homegrown mushrooms are harvested minutes before cooking.
- Cost Savings: Kits cost less than buying equivalent amounts of organic mushrooms from a grocery store.
- Education: Watch the entire life cycle unfold—great for kids and first-time growers.
- Low Maintenance: Button mushrooms thrive in dark, cool environments. Closets, basements, and under-sink cabinets all work.
Unlike gourmet mushrooms like oyster or shiitake, button mushrooms grow best in a compost-rich substrate and don’t require high humidity, making them more forgiving for indoor growers.

What to Look For in a Button Mushroom Kit
Not all mushroom kits are created equal. Here are some features to consider:
- Pre-inoculated substrate: Look for kits that arrive already colonized with mycelium to avoid contamination risk.
- Organic certification: Especially if you’re growing for children or culinary use.
- Yield potential: Some kits offer 1–2 flushes, while others yield over 3 lbs across several cycles.
- Size: Compact kits work well for countertops, while larger bins may need dedicated shelf or floor space.
- Support and Instructions: Look for kits with strong customer reviews and easy-to-follow guides.
How Long Do Button Mushrooms Take to Grow?
- Colonization: If your kit is not pre-colonized, this may take 2–3 weeks
- Pinning (Primordia Formation): Typically begins 7–10 days after applying casing layer
- Fruiting: Full-size mushrooms usually appear within 10–14 days of pinning
Most button mushroom kits will produce their first flush within 3–5 weeks of setup. After harvesting, you may see a second or third flush over the next few weeks.
Tips for Success with Button Mushroom Kits
- Keep in the dark: Button mushrooms don’t need much light—closets, cupboards, or shaded shelves are ideal.
- Mist regularly: Maintaining surface moisture is key, especially after applying the casing layer.
- Don’t overwater: The substrate should be damp, not soggy. Too much water can cause bacterial blotch or rot.
- Harvest early: Pick mushrooms when the caps are still rounded and before the gills are exposed for best flavor.
- Reuse the kit: Some kits can be “recharged” with new substrate or reused after a break.
FAQs About Button Mushroom Kits
Are button mushroom kits worth it?
Yes—for most beginners, they’re a cost-effective and fun way to learn mushroom cultivation with minimal risk.
What do button mushrooms grow on?
Composted manure or rich organic matter. Many kits use a sterilized composted substrate pre-inoculated with mycelium.

Can I reuse the growing tray or container?
Yes. Many kits come with reusable trays that can be cleaned and filled with fresh substrate.
