Greenhouse kits let you grow more, start earlier and keep plants safe through cold snaps, all without hiring an architect or a builder. At Mulberry Greenhouses we carry the best greenhouse kits for home gardeners: DIY hobby kits in glass, polycarbonate and cedar, from small starter kits to grand Victorian glasshouses. Every kit ships free to mainland US addresses, and real people in Atlanta, GA help you pick the right one.

How to Choose the Best Greenhouse Kit

The best greenhouse kit is the one that fits your space, your climate and how you plan to grow. Start with these four questions:

  1. How big? Most gardeners wish they had bought one size larger. Shop by size: small greenhouse kits, medium greenhouses and large greenhouses.
  2. Glass or polycarbonate? Glass greenhouse kits give the clearest light and a timeless look. Polycarbonate greenhouses insulate better, diffuse light evenly and stand up well to hail.
  3. Freestanding or lean-to? A freestanding kit gets sun from every side. A lean-to greenhouse attaches to your house or garage, saves space, and keeps water and power close.
  4. What is your climate? In cold or snowy regions, look for strong framing, insulating panels and good snow-load ratings. In hot climates like ours in Atlanta, GA, plan for plenty of roof vents, fans and shade cloth.

Greenhouse Kit FAQ

What size greenhouse kit should I buy?

For seed starting and a few tomatoes, an 8'x10' is a comfortable start. If you want to grow year-round, add benches or keep citrus, look at 10'x15' or larger. When in doubt, go one size up; almost no one regrets the extra room.

What is a hobby greenhouse?

A hobby greenhouse is a backyard greenhouse built for home gardeners rather than commercial growers. Every kit in this collection is a hobby greenhouse, sized and priced for a home garden.

Do greenhouse kits need a foundation?

Most permanent kits need a level, solid base such as a concrete slab, pavers, a timber frame or a perimeter footing. Some models offer a matching base. Our greenhouse foundation guide explains the options, or call us and we will help you plan.

How hard is a DIY greenhouse kit to assemble?

Small polycarbonate kits are often a weekend project for two people. Larger glass and cedar greenhouses take longer and more care. If you would rather not build it yourself, see our assembly crews page. We are not affiliated with any crew, but we can share a list of crews our past customers have used.

Is shipping really free?

Yes, to any mainland US address. Islands, Alaska, Hawaii and some remote locations need a freight quote, so please call 678-408-8222 before ordering. See our shipping policy for details.
