Thanks for buying your mushroom liquid cultures from Mush Love Genetics.
Returns
Our liquid cultures are living mycelium. Once a syringe leaves us, we cannot check how it was stored or handled, so we do not accept returns.
When we replace a syringe
We send a free replacement when a liquid culture syringe:
- arrives broken, leaking, or missing a part,
- is the wrong variety,
- arrives visibly contaminated, or
- shows no growth within 14 days after you inoculate properly sterilized grain with it.
A clean culture has clear broth with white to cream wisps or clumps of mycelium. The clumps are the culture and are normal. They settle to the bottom when the syringe stands and spread out when you shake it. Broth that stays cloudy or milky after it settles, a slimy film, green, black, or other colored growth, or a sour smell means the culture is contaminated.
A culture shows no growth when you inject it into sterilized grain using sterile technique, keep the grain at room temperature, and see no white mycelium on the grain within 14 days of inoculation. To qualify, you must have stored the syringe as its product page says and used it within the time the product page gives.
If every jar or agar plate from one syringe grows the same mold or bacteria and no mushroom mycelium, send us photos. We decide these cases one at a time.
If you are not 100% satisfied with your purchase for another reason, contact us. You may still be eligible for a replacement.
How to ask for a replacement
- Contact us no later than 14 days after the culture’s use-by date. The use-by date is on its product page: 3 months after delivery for most cultures and 1 month for pink oyster. Use the contact form at https://www.mushlovegenetics.com/contact-us/ or email info@mushlovegenetics.com.
- Include your order number.
- Attach photos. For damage or contamination, photograph the syringe against a plain light background after it has stood for an hour. For no growth, photograph the grain jars or bags, and tell us the date you inoculated them and how you sterilized the grain.
- Keep the syringe until we reply. We may ask how you stored it.
We ship replacements at no cost to you. If the variety is out of stock, we will offer a different variety of equal value or a full refund, whichever you prefer.
What we do not cover
- Contamination that shows up after you inoculate grain, agar, bulk substrate, or grow bags, unless every container from one syringe shows the same contamination as described above. Those results depend on your sterile technique, equipment, and growing space.
- Slow growth, small yields, or mushrooms that do not fruit.
- Syringes that were frozen, left in the heat, or stored in direct sunlight, and pink oyster cultures that were refrigerated.
- Cultures used after the time given on the product page.
- Orders delayed or returned because of an incorrect address entered at checkout.
- Changing your mind after the order ships.
Lost or stolen packages
If your tracking shows the package as delivered and you cannot find it, first contact the carrier with your tracking number. Then contact us. We decide these case by case and may offer a discounted price or a coupon code to reorder.
Refunds
If we cancel your order before it ships, for example because a variety sold out, we refund the full amount to your original payment method.
Nothing in this policy limits any rights you have under your state’s consumer protection laws.
