First harvest in 3 weeks. Absolutely blown away.
I was skeptical - I've killed every plant I've ever had. But these bags really take care of themselves. The oyster mushrooms came out huge and I've already ordered three more kits.

Traditional mushroom cultivation is complicated, time-consuming, and easy to get wrong. Freshrooms removes every single obstacle so all you're left with is the fun part.
No preparation. No sterilization. No mess. No fear of contamination.
Freshrooms handles it all so you can just grow.
With our All-In-One Grow Bags you don’t need any experience or equipment. Just follow three simple steps.
Use liquid culture or spores - inject directly through the self-healing injection port.
Keep the bag at room temperature. When 50% of grains are colonized, shake to break up and redistribute the mycelium through the substrate.
When the first pins appear, it’s time. Open the bag, let in fresh air, and watch your mushrooms grow. Harvest in just 6-8 days.
Grain, substrate, filter patch - sterilized and sealed. Contains everything to grow mushrooms successfully. Works with any species.

Food. Medicine. And a world still being discovered.
Rich umami flavor, meaty texture that holds up to heat. Mushrooms replace meat in stir-fries, tacos, risottos, and pasta - and do it better than anything else plant-based. Once you cook with freshly harvested mushrooms, the ones from a supermarket feel like a different ingredient entirely.
High in protein, B vitamins, zinc, selenium, and beta-glucans. Low calorie, zero fat. Gram for gram, one of the most nutritionally dense foods you can grow at home - and freshly harvested mushrooms retain significantly more nutrients than anything sitting on a supermarket shelf for days.
Lion's Mane produces compounds studied for nerve growth factor support and cognitive function. Reishi has been used in traditional medicine for over 2,000 years as an adaptogen for stress and immune resilience. Chaga carries one of the highest antioxidant scores of any natural food. You can grow all of them.
Gourmet, medicinal, functional - our bags support the full spectrum of species. Whatever you want to cultivate, we have the substrate for it. Most growers start with oyster mushrooms and never stop discovering what comes next.
Everything you need to grow alongside your All-In-One bags. Lab-grade quality, ready to ship across Europe.

Zero contamination across 4 grows.
Tried other suppliers before - always contamination problems. With Freshrooms, 4 grows, zero issues. Fast shipping to Germany (3 days). Worth every cent.
Kids check on them every single morning.
Family project that became our favourite hobby. Lion's Mane came out beautifully. Support replied within hours, sent a replacement bag when I accidentally damaged one.
I've now gifted these to 6 people.
My Shiitake grow was so easy that I've bought kits for my parents, my sister, and three colleagues. Everyone loves them. The substrate quality is clearly top-notch.
The quality difference is unreal.
I thought shop mushrooms were fine until I tasted these. Freshly harvested oyster mushrooms taste completely different - richer, meatier, better. I'll never buy shop ones again.
Perfect for beginners. Actually foolproof.
No prior experience, no equipment, first grow worked perfectly. Clear instructions. Mushrooms appeared after 3 weeks and I got two big flushes from one bag.

Can't find your answer? Our team of growers replies within hours.
Chat with our teamAbsolutely. Mushroom cultivation is surprisingly beginner-friendly when the correct steps are followed. Most people can achieve great results even on their very first grow.
That depends on how advanced you want your setup to be. For most home growers, all you really need are disposable gloves, 70-80% isopropyl alcohol, and a simple water spray bottle. No expensive equipment is required, and everything you need can be purchased directly from us.
Our sterility guarantee is straightforward: if you receive a contaminated or damaged product, we’ll either send a replacement or provide a refund. Every product is prepared and packed with strict attention to quality and sterility.
From inoculation to first harvest is typically 5–8 weeks depending on species and temperature. Oyster mushrooms are fastest at around 4–5 weeks.
Most bags give 2–3 flushes (harvests). After the first flush, re-hydrate the block by soaking in cold water for a few hours and the second flush appears within 2 weeks.
Up to 2–3 months when kept at room temperature in a clean and dark place. For best results, inoculate as soon as possible after delivery.
Our collection includes various oyster mushroom species, Lion’s Mane, multiple Shiitake strains, Reishi, Maitake, and many other carefully selected gourmet and medicinal mushrooms. We’re constantly working on expanding our lineup with new species and high-quality genetics for growers of all experience levels.
