Greenhouse Kits for Every Garden
Find the right greenhouse kit for your space, climate, and growing goals. Growing Spaces offers greenhouse systems for everything from compact season extension to year-round food production.
Choose a Growing Dome® greenhouse kit for four-season growing and challenging climates, a Growzebo™ for three-season backyard gardening and season extension, or a Simple Garden Systems cold frame for smaller spaces, seed starting, and crop protection.
Explore our greenhouse kits below and compare sizes, growing seasons, features, and applications to find the system that fits the way you want to grow.

What should your greenhouse kit do?
Cold frames, the Growzebo™, and Growing Domes solve different problems. A cold frame protects seedlings or a limited bed without creating a walk-in work area. The Growzebo provides a three-season greenhouse with room to work inside. Compare the six Growing Dome sizes when the project calls for a dedicated, four-season-capable greenhouse.
Next, account for the work around the structure. A bed-level system remains part of an existing garden. A walk-in greenhouse needs room for paths, watering, crop care, and summer ventilation. A Growing Dome project also requires planning for the site, foundation, utilities, interior, and routine operation.
Compare cold frames, the Growzebo, and Growing Domes
Use the primary job and operating season to narrow the list. Then confirm the current product specifications and local site requirements before ordering.
| Growing system | Primary job | Growing calendar | Planning scope |
|---|---|---|---|
Simple Garden Systems cold frames | Protect an existing bed, seedlings, or a limited planting area. | Seasonal protection and season extension, based on the crop and local conditions. | Bed fit, placement, access, ventilation, and regular crop observation. |
Growzebo™ greenhouse | Create a walk-in space for backyard growing, seed starting, and season extension. | Three-season. | Site exposure, local wind and snow requirements, ventilation, shade, interior use, and cold-weather expectations. |
Growing Dome® greenhouse kit | Create a dedicated, walk-in greenhouse for four-season growing. | Four-season capable; crops, climate, and temperature goals determine whether supplemental heat or light belongs in the plan. | Site, foundation, engineering, utilities, interior planning, installation, and ongoing climate management. |
Choose a greenhouse for three-season or four-season use
The Growzebo is a three-season greenhouse. It provides walk-in room for seed starting, plant care, and season extension when its current wind and snow specifications fit the site. Confirm local requirements before choosing it for a specific property.
Growing Domes are designed for four-season use and to be repaired one component at a time. Individual struts, hubs, and panels can be replaced without dismantling the entire structure. Pond thermal mass, north-wall insulation, ventilation, and undersoil air circulation belong to the Growing Dome design and do not apply to the Growzebo or cold frames. Match the Dome size and configuration to the crops, winter sunlight, outdoor temperatures, summer heat, local loads, utilities, and the lowest indoor temperature you want to protect. Use the four-season greenhouse guide and weather-resistant greenhouse guide for more detailed planning.

Match the project scope to daily use
Picture an ordinary growing day. Trace where water, soil, trays, tools, and harvested crops will move. Allow enough room to reach plants, work between beds, and manage irrigation, vents, shade, or monitoring. Floor area matters, but the work routes determine how much of it remains useful.
Cold frames keep the work at bed level. The Growzebo adds walk-in paths and room for owner-planned beds, benches, or open workspace. A Growing Dome adds the pond area, plus site, foundation, utility, interior, and operating decisions specific to a full four-season greenhouse. For a Growing Dome, keep the kit separate from owner-supplied materials, site work, beds, and optional systems when you set the project budget. Use the greenhouse buying guide for a broader project checklist or the greenhouse comparison guide if you are still deciding among product formats.

Discuss a full Growing Dome project
If a four-season greenhouse is the likely path, bring the location, crop and operating-calendar goals, preferred size or approximate space needs, and what you know about sun, grade, water, power, wind, snow, and access. You do not need every detail resolved before contacting Growing Spaces. For bed-level protection or a three-season Growzebo, use the product links above.
