Frequently asked questions

A successful order generates a confirmation email. If you do not see it, check spam or junk—confirmation emails are sometimes filtered, especially by iCloud and Yahoo. If it is still missing, email us with the name and email used at checkout so we can verify and resend it.

No. A confirmation means the order was submitted; it does not prove that a Cash App, Venmo, cash-by-mail, or cryptocurrency payment was completed. We cannot ship until payment is received. If you believe you paid but we cannot locate it, send a payment screenshot or transaction ID.

We accept major credit and debit cards, Google Pay, and Apple Pay through the website. Other options may include cash by mail, money orders, Cash App, Zelle, Venmo, and Bitcoin. Follow the instructions shown for the method you select. We do not accept PayPal.

We cannot add a new charge to a completed card transaction. Place a separate order and email us immediately with both order numbers. If the first order has not been packed, we will try to combine them, but this is not guaranteed.

Email us immediately with your order number and request. We can usually correct or cancel an order before it is packed or transferred to USPS. Once an order has shipped, it generally cannot be changed or canceled.

Yes—if you contact us before fulfillment. Include your order number and the complete corrected address. Once a package has shipped, contact USPS about any available intercept option. We cannot guarantee recovery of a package shipped to an address entered incorrectly at checkout.

We can issue an approved refund promptly, but the time for it to appear depends on your bank or payment provider. Please allow several business days.

We normally dispatch orders on business days, excluding federal holidays and weekends. The standard cutoff is 9:00 a.m. Eastern Time. Orders placed after that time generally ship the next business day. This schedule is subject to change and is not guaranteed.

A separate automated email with a 22-digit USPS tracking number is sent when the label is created. Check spam or junk if it is missing. Enter the number into Google or the USPS tracking tool.

Our rural post office does not always provide the first scan. Many packages update after reaching the Louisville hub, and some are not scanned again until they are out for delivery. If “Label Created” remains unchanged for more than 72 hours, excluding weekends, email us.

Complimentary shipping normally uses USPS Ground Advantage, typically estimated at 2–5 days. When available, expedited USPS Priority shipping can be selected at checkout and is typically estimated at 2–4 days. These are carrier estimates, not guarantees.

USPS delays and missed scans are outside our control. Contact your local post office with the tracking number and request a package inquiry. If a package has not arrived within 14 days and has not been marked delivered, email us so we can review it for reshipment under the shipping policy.

USPS sometimes marks packages delivered before final delivery, so allow a short period and check with household members, neighbors, and your local post office. Ask USPS to verify the delivery scan and open a missing-package report. We do not refund or reship packages marked delivered when the label used the customer-provided address.

No. Temperature packs do not reliably control a parcel for the full trip. Monitor tracking and retrieve the package promptly in extreme weather. You may also ask your post office to hold it for pickup.

Cultures generally tolerate normal transit conditions. The biggest risk is a delivered parcel sitting for a long time in extreme heat or freezing solid. Retrieve it promptly. If you suspect damage, test the culture and email us with your order number, photos, and results.

We currently ship within the United States and U.S. territories, including Puerto Rico, Guam, American Samoa, and the U.S. Virgin Islands. International shipping is not currently available.

We source cloned and isolated genetics through trusted, verified sources and produce cultures in a professional commercial lab environment. Batches are tested to verify viability and screen for contamination before release.

Color, clarity, and visible mycelium vary by culture and recipe. Nutrients, peptones, sugars, and normal caramelization can change the appearance without indicating contamination.

A small red piece may be a sterile injection-port plug. Brown flakes may be bacterial peptone used in the nutrient solution; peptone can clump during preparation. Neither one, by itself, proves contamination.

Refrigerate cultures when they are not being used for research. Do not freeze them; freezing can damage the live mycelium and reduce viability.

We recommend using a refrigerated culture within three months for optimal viability. Properly stored cultures can remain viable far longer—sometimes beyond a year—but the product guarantee lasts 70 days from delivery.

Usually, yes. Properly prepared cultures can tolerate normal room temperature for an extended period. Refrigerate after receipt and test if concerned. Freezing solid or prolonged extreme heat is the greater risk.

Cultures are guaranteed to be viable and free from contamination for 70 days after delivery. Within that period, a confirmed product issue may qualify for one complimentary reshipment or a refund, within reason and subject to the complete Refund & Replacement Policy.

Do not use a compromised syringe. Email us promptly with the order number and clear photos of the syringe, cap, label, packaging, and leaked material. Confirmed transit damage will be reviewed for replacement.

Not necessarily. Nutrient sediment, an injection-port fragment, culture-specific color, and normal cloudiness can look unusual. Appearance alone is not conclusive, so we may ask you to test the culture on agar or grain.

Email us within the guarantee period with your order number, affected variety, clear photos of the syringe and label, and photos of the test medium, container, lid, and injection area. Include a brief description of the test and observed result. Agar or grain test results help us verify the issue quickly.

Generally, no. Normal nutrient material can resemble contamination. We will review photos, but testing is usually needed to confirm whether a culture is contaminated or inactive.

We advise against all-in-one kits because they have higher contamination and failure rates. Products used with an all-in-one kit are not eligible for reshipment or refund under the current policy.

You may have checked out as a guest or used a different email address. Email us with the order number and possible checkout emails. If you create an account using the same email, we can review whether the guest order can be attached to it.

First confirm that an account exists under that email; guest checkout may not create one. Check spam for the reset message and try again. If the reset loop continues, email us with the account email and username.

Support is handled by email. This gives us a written record and lets us accurately review photos, tracking, order details, and test results.

Yes. Our 20% lifetime service discount is available after verification for military veterans, active-duty military, law enforcement, firefighters, EMTs and paramedics, search-and-rescue personnel, 911 dispatchers, doctors, nurses, and other verified first responders.

Apply using the service discount form →. Once your service is verified, we will email your personal, never-expiring discount code within 2 business days. Your code is for your personal use only.

Complete the service verification form on our Military & First Responder Discount page. Enter your first name, last name, email, shipping address, and type of service, then upload your proof.

Accepted proof: a service certificate; discharge or separation record (such as a DD214); veteran-status document; professional license or certification; employer or department letter; work ID or badge; or an ID.me screenshot showing your name and verified qualifying service status. Other documents are welcome if they clearly verify your qualifying service.

Upload one JPG, PNG, or PDF up to 5 MB. Your name and proof of qualifying service must remain visible; everything else may be blacked out.

Prefer to email, or having trouble with the form? Send your first and last name, shipping address, type of service, and proof directly to Anthony@CubeCultureUSA.com instead.

We have checks and balances in place to review service claims. False information, altered proof, and attempts to steal valor are not tolerated. False submissions will result in denial of program access or revocation of the discount.

No. We do not provide cultivation or consumption advice. Support is limited to orders, shipping, product identification, suspected quality issues, and lawful microscopy research.

Our cultures are sold only for lawful microscopy and research and are formulated without active alkaloids. Laws can vary and change, so customers are responsible for checking current state and local rules. Product availability is not individual legal advice.

No. We do not diagnose conditions, provide medical advice, or recommend products or substances as treatment. Please speak with a licensed healthcare professional.
