Owner Supplied Items: The Growing Dome® is purchased as a greenhouse kit ready for assembly by owner, contractor, or Growing Spaces crew (33′ kits require at least a Growing Spaces Certified Supervisor and the 42′ kit requires a Certified Supervisor plus one Growing Spaces crew member). However, since a few items are bulky and costly to ship, and available at your local building supply store, they are not included in the greenhouse kit. Doing this lowers the overall cost for the Growing Dome owner. See the Technical Specifications page for more information on Owner Supplied Items.

Shipping / Delivery: Growing Spaces delivers and/or ships within the United States and also ships Internationally. Shipping / delivery, crating, and handling charges are not included in the price of the Growing Dome kit. See our Shipping page for more information on how to receive a quote. Local sales taxes do apply for customer pick-up. For more information on our shipping policy please visit Terms & Conditions – Our Product.

Installation is not included in the above prices. You may install the Growing Dome yourself (26′ Dome and smaller), hire a Growing Spaces Installation Supervisor to direct your crew, or you may choose to have our Full Crew install your Growing Dome kit. See details and prices on the Greenhouse Build Options Page or call us at 800-753-9333 for a quote.
