PAYMENT

Purchasers planning for permitting or funding processes may secure current pricing with a 10% deposit on the dome kit. This pricing is valid provided that shipment is completed within four (4) months of the deposit date. The initial 10% deposit is fully refundable at any time prior to the Purchaser submitting the additional 40% production deposit.

If delivery does not occur within the four-month period:

  • The 10% deposit may be refunded, or applied to an updated price if mutually agreed.
  • If a 50% deposit has been made, the order may be subject to storage fees and restocking charges, or the final payment may be adjusted to reflect current pricing upon mutual agreement.

Purchasers who do not require permits or do not wish to pursue permitting may bypass the 10% deposit step and proceed directly with a 50% deposit to initiate manufacturing. This will place the order into the production queue and schedule it for shipment accordingly. A production confirmation will be issued once the deposit is received.

The remaining 50% of the dome kit cost is due one week prior to the scheduled shipment date.

We accept ACH/e-check, wire, debit, major credit cards, and Affirm monthly payments for eligible purchases.

Using Affirm

  • The deposit model does not apply when using affirm. Your order enters production only after full Affirm approval for the entire order. If approval is not granted or is withdrawn prior to release, you may switch to a non-Affirm method and follow our standard deposit milestones.
  • Affirm is a third-party lender. Your application, credit decision, APR/fees, and repayment are between you and Affirm.
  • Paid in full requirement. When you select Affirm at checkout, your entire cart total must be approved and paid through Affirm. We do not accept partial payments, deposits, or split tenders when using Affirm.
  • Down payment & schedule. Affirm may require a down payment at checkout and limit the methods in which the down payment is paid (such as debit card only); the remainder is financed with Affirm on the schedule you accept.
  • Order release. We will release your order into our workflow only after Affirm approval for the full amount and authorization is received.
  • Loan issues (payments, fees, delinquency, credit reporting) are handled directly with Affirm and do not pause our production/shipping once an Affirm paid order has been released.
  • When you choose Affirm, you share information directly with Affirm under their privacy policy; we do not receive your full credit details.

SHIPPING

Growing Spaces will choose the shipping method and schedule based on cost and timing, with typical lead times of 4–8 weeks depending on the season. You’ll be notified when your order has a production and ship date, and you’ll receive tracking once it leaves our facility. We ask carriers to provide a 24-hour call-ahead to schedule delivery.

Shipping costs are non-refundable. Once your order is picked up, risk of loss or damage transfers to the carrier. While we don’t insure shipments, we’ll help you work with the carrier and support you in filing damage claims. Any damage must be reported at delivery, noted on the freight paperwork, and documented with photos.

Orders may ship up to five business days before the planned ship date, and any changes or postponements may incur fees. Growing Dome® kits ship in large, heavy crates via full-size tractor-trailer or large box truck. It is your responsibility to ensure your location can safely accommodate these vehicles, including enough space, height, width, turning radius, and suitable road conditions. If you need special arrangements (such as smaller trucks, liftgate, forklift, or offloading help), you must notify us before shipment; any extra charges or redelivery due to access issues are your responsibility. Financing does not change lead times, shipping coordination, risk transfer, or your responsibility to inspect and report any damage.

SALES TAX

Sales taxes will be calculated and applied according to each state requirements on all purchased items including dome kits, merchandise and parts.

OWNER SUPPLIED ITEMS

There are certain items needed for building the Growing Dome kit that are very bulky, costly to ship, and inexpensively available at your local building supply store. These items are not included in the Growing Dome kit to help lower the final cost. Most materials are easily found at your local hardware supply store, but the sheet metal can be found at a heating & air conditioning (HVAC) or sheet metal supply store.  More about owner supplied items here.

CANCELLATION POLICY

Orders cancelled at any time are subject to a 5% restocking and processing fee, deducted from any refund due.

If the order is cancelled within 20 business days of the scheduled shipment date, an additional 5% of the full order value will be withheld (total 10%). The remaining balance will be refunded within 90 days of cancellation to allow for material reconciliation, scheduling updates, and refund processing.

Cancellations are not permitted for custom orders, defined as changes to structural design, size, or non-standard component substitutions. In practice, this means that the production deposit for a custom order will be forfeited upon cancellation. Growing Spaces will not enforce delivery for unpaid custom orders.

When using Affirm:
Our normal change/cancellation rules apply. If you cancel an Affirm-financed order, any eligible refund of amounts already captured will be routed back to Affirm; Affirm will adjust your loan per its terms. If you change your order (options, pricing, add/remove items), we will:

  • attempt an Affirm amount adjustment (subject to Affirm approval), or
    process the difference via a non-Affirm payment method before the order proceeds.

RETURNS

All sales are final. We do not accept returns or exchanges. Order cancellations are permitted prior to shipment. Once an order has shipped, it can no longer be canceled.
