Equipped with self-healing injection ports and 5-micron filter patches, it ensures optimal gas exchange and contamination protection. Designed for indoor use, this kit supports large, healthy mushroom yields with easy setup and flexible storage options, making it ideal for both novice and experienced cultivators. ## Description The Mushroom Grow Kit (Quick Kit) is the ultimate solution for growing gourmet mushrooms at home with ease. This kit includes two pre-sterilized substrates: a 1-pound bag of organic, hydrated, and sterilized rye berries for creating your spawn, and a 1-pound bag of manure-based mushroom substrate to serve as the bulk substrate. The rye bag, equivalent to 1 quart in volume, features a self-healing injection port and a 5-micron filter patch to ensure optimal gas exchange. The bulk substrate, equal to 1.5 quarts, is crafted from high-quality horse manure and fortified with essential nutrients to support healthy and productive mushroom growth. To use the kit, simply inoculate the rye bag with 4cc of your favorite gourmet mushroom culture and shake to distribute evenly. Allow the rye bag to colonize at room temperature for 5 to 6 weeks. Once fully colonized, break up the mycelium in the rye bag and mix it with the manure substrate bag. Seal the bag and allow it to colonize at room temperature for another 4 to 6 weeks. Mushrooms can be grown directly in the bag or transferred to your preferred fruiting chamber for cultivation. Both substrate bags can be stored for up to 4 months at room temperature or 6 months in refrigeration, making this kit as convenient as it is effective. Out-Grow takes pride in using only organic ingredients to create high-quality mushroom substrates. This kit is perfect for both beginners and experienced growers, offering an easy and reliable way to produce mushrooms with large, healthy fruits. Review: Placing my 4th order - My 1st order I injected 10cc of Golden Teacher spore solution without reading the instructions. This was too much liquid, only supposed to use 4cc, which caused contamination. My next 2 worked perfectly. My only complaint is there needs to be another 1/2 to 1lb of manure. The vast majority of negative reviews are due to human error (except the ppl who claim to have received precontaminated bags). A sterile environment and sterile inoculation techniques are vital or you will fail. I've been growing for over 20 years and I still have contamination occasionally so to blame a product you've only tried once for contamination or lack of mycelium growth is ridiculous. Of course it's cheaper to make your own spawn bags/jars but for beginners, and lazy bastards like me, this kit is perfect. My last harvest I got a few grams shy of 1/4lb dried and still have 6cc of spore solution left. That comes out to about $3.50 a gram so if you're interested in mycology or are just sick of paying street prices for something you can grow without need of special lights etc. and zero odor I'd recommend getting this Review: Worked - Got some good crop. Don't have the prefect set up, but did fine. Would but again. ## Features - Ready-to-Use Mushroom Grow Kit: Includes pre-sterilized rye grain and manure-based substrate for easy setup. - Beginner-Friendly: Perfect for new growers and experienced cultivators alike. - Convenient and Compact: Ideal for small-scale or experimental grows. - Premium Features: Grow bags include self-healing injection ports and 5-micron filter patches. - 100% Organic Ingredients: Supports large, healthy mushroom yields with fortified nutrients. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07P9C8FCB | | Brand Name | Out-Grow | | Colour | Black | | Customer Reviews | 4.0 out of 5 stars 812 Reviews | | Included Components | Sterilized Rye Berries, Horse Manure Based Mushroom Substrate | | Item Package Weight | 1.04 Kilograms | | Item Weight | 454 g | | Manufacturer | Out-Grow® | | Number of Pieces | 2 | | Part Number | MGK-QuickKit | | Size | Small | | UPC | 616576243194 | | Unit Count | 1 Count | ## Product Details - **Material:** Rye Berries, Horse Manure-Based Substrate - **Colour:** Black - **Special Feature:** Self-Watering - **Style:** Modern - **Planter Form:** Bag ## Images ![Mushroom Grow Kit (Quick Kit) - Image 1](https://m.media-amazon.com/images/I/71OhCGIp+cL.jpg) ## Questions & Answers **Q: If you fruit in the bag can you flush it?** A: Yes you can. After your first harvest mist heavily and close the top of the bag. Place on a shelf with the bag semi inflated and allow 2-3 weeks for your second flush to grow. **Q: How many CCs of spores should be used in the grain spawn?** A: The instructions said 4 ccs. **Q: Will this product grow majic mushroom??** A: Yes but the risk of contamination is high. I recommend the PF tech method. **Q: Can you use 2 different liquid spores in the rye bag? Or is this one type per bag?** A: No. The reason it is hermetically sealed if so you can develop the substrate for one particular spore. You have to be very careful or they will fight for dominance in the bag. The spore is gotten from any mushroom (even a porcini at the grocery store.). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Placing my 4th order *by T***L on 21 February 2022* My 1st order I injected 10cc of Golden Teacher spore solution without reading the instructions.

Don't have the prefect set up, but did fine. Would but again. ### ⭐⭐⭐⭐ Product was as advertised and contamination free. *by E***E on 2 April 2022* The grain bag was well hydrated and contamination free. My LC colonized the entire bag in about 15 days without issue. I haven’t used the substrate as of yet because it’s being saved for a specific strain. This kit is a decent value considering how booming at home mycology is currently but it’s still a little pricey for the amount of grain and substrate that you get. The price is kinda to be expected I suppose since you’re getting sterilized product that’s in bags with filters and self healing inoculation points. I would absolutely buy again for small quick grows or experimenting with a new dung loving specie. Edit: I went ahead and used the substrate that is part of the kit and it was fantastic. The grain spawn colonized it quickly, around 10 days if I remember correctly, and when it came time for first harvest I had almost a full canopy. Got 3 total harvest and probably could’ve got a 4th but I was having to really nurse it and pay close attention on the 3rd harvest. It held moisture really well and when I soaked the cake in between harvest it seemed to absorb the water quite well. This kit is as good as it gets for hobby type mycology. ## Frequently Bought Together - Mushroom Grow Kit (Quick Kit) - ‘Boomr Bag’ (5 lb) Manure-Based Sterile Mushroom Bulk Substrate | Maximum Yield Formula | Made in USA | Grow Dung-Loving Mushrooms | North Spore - Myco Labs Grower's Select Mushroom Monotub Fruiting Chamber with Filter Disks and Liner --- ## 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.co.uk/products/436296002-mushroom-grow-kit-quick-kit](https://www.desertcart.co.uk/products/436296002-mushroom-grow-kit-quick-kit) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-03*
