Our Complete Mushroom Grow Kit includes everything you need to create a clean, efficient growing environment for gourmet and edible mushrooms. Every component is carefully measured, sterilized, and packaged to remove the guesswork and deliver consistent results.

Premium Sterile Components

Inside the kit, you’ll find a 5-pound bag of sterile rye grain for preparing your grain spawn, along with two 5-pound bags of pre-measured CVG substrate made from coco coir, vermiculite, and gypsum. This balanced blend provides the ideal combination of moisture retention, structure, and nutrients for rapid mycelium colonization and strong mushroom growth.

The included 1-pound sterile casing layer provides a perfect top layer for fruiting, maintaining the right surface humidity and giving your mycelium the environment it needs to thrive. Each material is ready to use right out of the bag — no additional sterilization or hydration is required. Simply inoculate your grain, let it colonize, then mix with the substrate and apply the casing layer.

    Really great deal for this. I’ve bought it 3 times now and it makes prepping my mono tub super easy. Love the cute little bag of casing layer it comes with lol!

  3. Bill

    10/10 on the products themselves and 10/10 on customer service! One of the bags arrived smashed (looks like corner of box was smashed in transit) and they sent me a replacement with an extra bag. Great experience overall.
