what makes us different

What Makes GROmagic Special?

Simplicity at Its Best

With our all-in-one grow bag, growing mushrooms has never been easier. It's a hassle-free solution for both beginners and experienced growers.

Species Variety

Whether you prefer shiitake, oyster, or any other variety, GRO Magic is designed to support the growth of numerous mushroom species.

Medically sterilized and sealed polypropylene bag custom designed for our mushroom grow bags.

Mushrooms need oxygen to grow—our .2 micron air filter maintains proper gas and oxygen exchange while keeping contaminants out.

The “special sauce” of our mushroom grow bags: two pounds of our organic mushroom substrate—a blend of fully composted and aged manure, peat moss, vermiculite, coconut coir, gypsum, and coffee grounds.

Two pounds of organic golden rye grain—cleaned and soaked to provide the perfect amount of moisture for optimum mushroom growth.

Self-healing injection port prevents contamination.

Organic and Sustainable

We prioritize the use of organic, sustainable materials in our grow bags. You can feel good about what you're growing and how you're growing it.

Contamination Free

Our grow bags are crafted to prevent contamination, offering a secure environment for mushroom growth. Cultivate with confidence in a clean, safe setting.

GROmagic Bag

The 3 Steps to the Magic!

Step 1

Introduce spores delicately place your chosen mushroom spores into the self-sealing injection port of the bag.

Step 2

Once you notice the bag undergoing a transformation, with the appearance of white mycelium, gently agitate the bag to ensure even distribution of the mycelium throughout the entire bag.

Step 3

Watch as the mycelium network develops, and your mushrooms start to grow.  Once the mushrooms are mature, harvest them and savor the freshest, most delicious fungi you’ve ever experienced.

Liquid Culture & Spores

Liquid culture, often abbreviated as LC, and spores serve as the essential starting points for cultivating mushrooms. Offered in liquid form and syringes, these can be effortlessly injected into a GROmagic Bag. Opting for liquid culture is recommended over spores due to its quicker growth and increased resistance to contamination. Both liquid culture and spores are available for separate purchase from various online vendors. Upon ordering a GROmagic Bag, your confirmation email will include a list of reputable online retailers specializing in liquid culture and spores with whom we have partnered.

Lab-Tested for Purity & Potency

All spores at SporesMD are lab-tested by a third party to ensure purity, potency, and sterility. They are processed in a certified ISO-7 cleanroom under cGMP protocols, maintaining strict environmental controls. Spores are sourced from pesticide-free, non-GMO farms, and every product comes with a guarantee of clean genetics and top-tier quality.
