Quick Answer: The best cedar greenhouse kit for most buyers is the BlueWish 8x10 FT Cedar Greenhouse Kit — a cedar-frame structure glazed with 6mm polycarbonate panels, with an adjustable roof vent and lockable door, sized to fit a standard backyard footprint without dominating the yard. Want something smaller to start? The BlueWish 6x8FT cedar kit trims the footprint and price. Want an all-solid-cedar build rather than just a cedar frame around polycarbonate walls? The Veikous 8x8 Cedar Greenhouse ($999.99, per Veikous’s own listing) is the pick.
Every kit we’ve reviewed on this site so far — Palram, Exaco, Quictent, Riga — uses an aluminum or steel frame. Cedar is the wood-frame alternative: naturally rot- and insect-resistant without chemical treatment, and it holds warmth better overnight than bare metal. It’s a smaller, newer category on Amazon than the aluminum kits, but a handful of real options exist. Here’s how they compare.
Cedar greenhouse kits by the numbers:
- Naturally rot- and insect-resistant — the property that makes cedar the standard lumber choice for outdoor structures left exposed to weather year-round, the same reason it’s used for raised garden beds and outdoor furniture.
- $999.99 — Veikous’s listed price (regularly $1,099.99) for its 8x8 solid-cedar greenhouse with windows, per the manufacturer’s own site — the one cedar kit in this roundup with a manufacturer-confirmed price.
- 6mm — the polycarbonate panel thickness on BlueWish’s cedar-frame line across its 6x8 through 8x16 sizes, roughly matching the twin-wall gauge used on entry Palram kits.
- Every year or two — how often manufacturers recommend re-sealing or oiling an exterior cedar frame to preserve weather resistance and color, comparable upkeep to a cedar raised bed or fence.

1. BlueWish 8x10 FT Cedar Greenhouse Kit — Best Overall
BlueWish 8x10 FT Cedar Greenhouse Kit
- Cedar-frame construction with a 6mm-thick polycarbonate panel for the walls and roof.
- 80 square feet — big enough for a bench down one side plus a working aisle, without the assembly footprint of a full walk-in.
- Adjustable roof vent for passive summer airflow, plus a lockable door.
- Cedar naturally resists rot and insects without chemical pressure-treatment, and holds heat better overnight than a bare-aluminum frame.
Growers who want a cedar frame without either the smallest starter footprint or the cost of a much larger structure land on the 8x10. It’s roughly the same growing area as our best small greenhouse aluminum picks, but with a wood frame that ages to a warm gray rather than staying bare metal — and, unlike aluminum, it needs an occasional exterior seal or oil to keep that weather resistance up over the years.
2. BlueWish 6x8FT Cedar Greenhouse — Best Compact / Starter
BlueWish 6x8FT Cedar Greenhouse
- Same cedar-frame-plus-polycarbonate build as the 8x10, scaled down to a 48-square-foot footprint.
- Fits tighter backyards or a corner spot where an 8x10 or larger structure wouldn't clear a fence line or setback.
- Adjustable vent and lockable door carry over from the larger sizes in the same line.

If your entire goal is starting seeds a few weeks earlier or overwintering a handful of potted plants, 48 square feet of cedar-and-polycarbonate space is plenty, and the smaller footprint means less lumber and a shorter assembly weekend than the 8x10 or 8x14.
3. BlueWish 8x14FT Cedar Greenhouse — Best Large
BlueWish 8x14FT Cedar Greenhouse
- 112 square feet — the largest size in BlueWish's cedar-frame line, roughly 40% more room than the 8x10.
- Same 6mm polycarbonate panel and adjustable-vent, lockable-door spec as the smaller sizes.
- Enough length for benches on both long walls with a center aisle, similar in scale to our [best greenhouse for winter](/best/best-greenhouse-for-winter/) full-size picks.
At 112 square feet, this is the size where a cedar-frame kit starts to compete directly with a serious hobby aluminum structure rather than a backyard starter. Budget real assembly time — a cedar frame this size means more panels, more hardware, and more weight to manage than the 6x8 or 8x10, and a solid foundation matters even more given the added weight of wood versus aluminum.
4. Veikous 8x8 Cedar Greenhouse — Best Solid-Cedar Build
Veikous 8x8 Cedar Greenhouse with Windows
- Solid cedar construction rather than a cedar frame around polycarbonate wall panels — the most wood-forward build in this roundup.
- 64 square feet with windows built into the design for extra ventilation and light beyond the roof vent.
- Listed at $999.99 on Veikous's own site, regularly $1,099.99 — the only price in this roundup confirmed directly by the manufacturer rather than estimated.
- Also sold in larger 8x14 and 8x16 sizes for growers who want the solid-cedar build at full walk-in scale.
Veikous’s build philosophy is different from BlueWish’s — solid cedar throughout rather than a cedar frame wrapping polycarbonate panels, which means more wood, more natural insulation, and a heavier structure overall. The tradeoff is less light transmission through solid cedar wall sections than through polycarbonate, which the built-in windows partly offset. If the point of going cedar is maximizing the wood look and feel rather than just avoiding an aluminum frame, this is the pick.
How to choose a cedar greenhouse kit
- Decide if you actually want wood over aluminum. Cedar looks better and holds heat slightly better overnight, but it needs occasional resealing and costs more than a comparable aluminum kit like our Palram or Outsunny picks. If maintenance-free is the priority, aluminum wins.
- Size by growing goals, not the biggest number. 48 sq ft (6x8) suits seed-starting and overwintering a few plants. 80 sq ft (8x10) fits a bench and aisle. 112 sq ft (8x14) supports benching on both walls.
- Choose frame-only cedar vs. solid cedar. BlueWish’s polycarbonate-panel-in-a-cedar-frame builds let in more light; Veikous’s solid-cedar build trades some light for a heavier, more wood-forward structure.
- Plan the maintenance cycle. Budget an exterior sealant or wood oil every year or two, the same upkeep as a cedar raised bed or potting bench, to keep the frame’s rot resistance intact long-term.
- Don’t skip the foundation. Wood-frame kits carry more weight than aluminum ones — see our greenhouse foundation guide before ordering.
