Allow the beauty of fungi to brighten your kitchen and its deliciousness enhance your family dinner. Growing your own healthy and delicious mushrooms has never been easier, and you can do it year round with a North Spore 'Spray and Grow' Kit. No experience necessary. Activating your kit: 1) Inside this box is an amended sawdust block that has been completely colonized by mushroom mycelium. Open your kit along the perforated line and dispose of the remaining cardboard. 2) Slice an 'X' into the plastic underneath with a sharp knife or scissors. 3) Fill the sprayer included in your kit with tap water and spritz the plastic where you sliced your 'X' shape. Spritz your kit at least twice daily - more if you're in a particularly dry climate. 4) Place your kit in the most humid part of your home and outside of direct sunlight. We suggest putting it on a kitchen counter close to a sink. The mushroom mycelium will sense the oxygen in the air and produce mushroom 'pins' - another word for 'baby mushrooms.' This will usually happen within two weeks of slicing the plastic. 5) Harvest before the caps flatten out and become concave. Mushrooms grow quickly, so when you spot your first pins, keep an eye on them. The warmer the environment the faster they will grow. Mushrooms should be ready to harvest 2-5 days after pin formation. ## Features - Blue Oyster Mushrooms (Pleurotus ostreatus) are delicious, contain very little fat and are high in both protein and fiber, riboflavin and niacin.

Very easy. It started pinning in 2 weeks. And it’s doubling in size everyday. So exciting! ### ⭐⭐⭐⭐⭐ Fun project *by L***E on Reviewed in the United States on 20 October 2023* Great project for kids to learn about mushrooms and enjoy eating the results. Once package was opened and spritzed kept under bathroom sink so kids could easily check on and rehydrate. We had a large batch of mushrooms within days. ### ⭐⭐⭐⭐⭐ Amazing! *by K***X on Reviewed in the United States on 30 July 2022* First time experiencing growing mushrooms!!! It started to sprouts exactly 2 weeks. I love it! And watching it grow! Will buy again.Update 10/8: So it’s been almost 3 month since I got the mushrooms kit. Thru those time I harvest it 3 times, only the 1st round have more mushroom sprouting. There were 2 other times that the mushrooms were having hard times growing n it went dead, then I realized my house is too dry to the point I almost threw the kit in the trash having no more hope. But I gave it one last chance to see if it’s still grow outdoor during fall season. Instead of just putting the block outside, I broken in half, smash them in 2 jug(1 clear, 1 milk jug) on top of some garden soil with dried grass on top and watered to see if that work. I left it outside in a shaded spot didn’t check for a week until now n amazing!!! It’s still growing, even better!! Got pictures too. ## Frequently Bought Together - North Spore Organic Blue Oyster Mushroom Spray & Grow Kit (4 lb) | Beginner Friendly & Easy to Use | USDA Certified Organic, Non-GMO | Handmade in Maine, USA - (2-Pack) North Spore Organic Lion's Mane Mushroom Spray & Grow Kits (4 lbs each) | USDA-Certified Organic, Non-GMO, Beginner-Friendly & Easy to Use | Handmade in Maine, USA - North Spore Organic Pink Oyster Mushroom Spray & Grow Kit (4 lbs) | USDA-Certified Organic, Non-GMO, Beginner-Friendly & Easy to Use | Handmade in Maine, USA --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/376806081-organic-blue-oyster-mushroom-spray-and-grow-kit-4-lb](https://www.desertcart.vu/products/376806081-organic-blue-oyster-mushroom-spray-and-grow-kit-4-lb) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-16*
