Ready-to-fruit oyster mushroom grow kit

A pre-colonized grow kit is the fastest path from purchase to plate. The substrate block is fully colonized with mycelium — just cut an X in the bag, mist daily, and harvest in 7-10 days.

Recommended Kits

• North Spore Spray & Grow ($20-30): Comes with a spray bottle and detailed instructions. Blue or pink oyster. Reliable 2-3 flushes.
• Back to the Roots Mushroom Kit ($15-20): Available at Target, Whole Foods, and Amazon. Pearl oyster on coffee grounds. Good for kids and classrooms.
• Smallhold Home Kit ($25-35): Premium substrate blend. Consistently high yields.

What to Expect

• First harvest: 7-10 days after opening the kit
• Yield per flush: 0.5-1 lb
• Total flushes: 2-3 over 4-6 weeks
• Total yield: 1-2.5 lbs per kit

Tips

• Place the kit in a humid spot with indirect light — a kitchen counter near a window is ideal
• Mist 3-4 times daily or place a loose plastic bag over the kit as a humidity tent
• After the kit stops producing, break it apart and bury chunks in a shaded garden bed — outdoor flushes often appear in fall
