Grow Kit Facts

Quick facts about Mini Mushroom Farms grow kits, gift sets and shipping.

What is a Mini Mushroom Farms grow kit?

A 4.3 lb, ready-to-fruit block that's already full of mushroom mycelium. You open it, mist it, and mushrooms grow right out of the box. Every kit comes with a temporary humidity tent, a spray bottle and a sanitizer wipe.

Which mushrooms can I grow?

Blue oyster, Nevada blue oyster, pink oyster and lion's mane.

How long until the first harvest?

In the right conditions, oyster kits start growing in 7–10 days. Lion's mane is slower, usually 2–3 weeks.

How much does a kit produce?

On average, oyster kits yield ¾ to 1 lb on the first harvest, and lion's mane about ½ to 1 lb per harvest. Later harvests yield about ½ lb each, with the next one usually ready 2–3 weeks after you pick.

Is the first harvest guaranteed?

Yes. Your first harvest is guaranteed when the kit is used within 6 weeks after delivery. If it doesn't fruit, contact us and we'll send a replacement or refund you.

Do I need experience or equipment?

No. Keep the kit at 18–28 °C in indirect light, inside the included tent, and mist it 2–3 times a day. The tent keeps humidity above 70%, which mushrooms need.

What's in the gift sets?

• Grow Tent Gift Set + Grow Kit: a reusable 35 × 35 × 32 cm grow tent, a hygrometer, a spray bottle and a grow kit of your choice.
• 2 Grow Tent Gift Sets + 2 Grow Kits: two of everything.
• Grow Kit Variety Pack: all four kits, with a temporary tent, a spray bottle and a sanitizer wipe.
• 2 Grow Kits Bundle: two kits of your choice, with a temporary tent, a spray bottle and a sanitizer wipe.

Can I store a kit before starting it?

Yes. Keep it in its box somewhere cool and dry. All kits except pink oyster can go in the fridge, which helps them keep longer. The guarantee period still applies.

Where do you ship, and how long does it take?

• Canada: $14.91 CAD, free on orders over $100 CAD, 3–6 business days.
• United States: $13.42 USD, free on orders over $90 USD, ships from Illinois in 3–5 business days.

Can I return a kit?

Grow kits and gift sets that include a kit are final sale, but they're covered by the first-harvest guarantee. Unused tents and accessories can be returned within 30 days. See the full return policy.

What do I do with a finished kit?

Remove the plastic bag and compost the block, or mix it into garden soil. It makes great fertilizer.
