If the substrate is the soil, mushroom spawn is the life that runs through it. It’s when the whole thing really begins – the part that takes your mix from a bag of damp material to a living, breathing grow. Good spawn doesn’t just make a difference; it changes the whole experience. Strong clean mycelium spreads fast, fights off contamination, and rewards you with those thick healthy flushes that every grower wants to see.

Our mushroom spawn bags come fully colonised and ready to use. Theres no messing around waiting for spores or liquid cultures to take off or wondering if something’s gone wrong—it’s all there alive and kicking, just waiting for the right substrate. Open the bag, mix it in, and let nature handle the rest. It’s low effort, high reward.

You’ll find all the classics here – Lion’s Mane, Blue, Golden and King Oyster and even Shitake and Reishi for the patient types. Each grain spawn bag is prepped in sterile conditions, tested for strength, and designed to work with monotubs, blocks, or our mushroom grow kits. Pair them with our substrate mixes, keep the humidity steady, and you’re set. It’s the simple way to grow more with less stress.
