Best Cedar Greenhouse Kit 2026: Wood-Frame Picks Compared

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 a published manufacturer price, side windows and sizes up to 8x16? The Veikous 8x8 Wood Frame Greenhouse ($899.99–959.99 on Veikous’s own store, October 29, 2026) uses the same cedar-frame-plus-polycarbonate build.

Last updated: October 29, 2026 — corrected the Veikous description (Veikous’s listing specifies a solid cedar frame with multi-layer polycarbonate panels, not solid wood walls), refreshed Veikous prices from its own store ($999.99 in August to $899.99–959.99 now) and added its 8x10 to 8x16 sizes and its aluminum-kit price for comparison.

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.
• $899.99–959.99 — Veikous’s own-store price on October 29, 2026 for its 8x8 cedar Wood Frame Greenhouse (black vs. natural Burlywood finish, list price $1,099.99), down from the $999.99 we recorded in August. The same store listed Veikous’s 8x8 aluminum-frame polycarbonate kit at $589.99, so the cedar frame costs roughly $310–370 more for the same footprint.
• 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. For reference, Palram rates its own 6mm clear twin-wall sheet at 80% light transmission and a U-value of 3.5 W/m²K — our greenhouse panels guide shows how thickness changes light and insulation.
• 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.

Best cedar greenhouse kits at a glance

1. BlueWish 8x10 FT Cedar Greenhouse Kit — Best Overall

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

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

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 Wood Frame Greenhouse — Best Size Range

Correction (October 29, 2026): an earlier version of this page described the Veikous as solid cedar throughout, with solid wood wall sections that let in less light. Veikous’s own listing describes a solid cedar wood frame glazed with multi-layer polycarbonate panels — “solid” describes the lumber, not the walls — so it admits light the same way the BlueWish kits do.

What sets the Veikous apart is a side window on every size, a price published directly by the manufacturer, and a range that runs from 8x8 to 8x16 in two finishes. It also puts a number on the cost of choosing wood: on the same day, Veikous’s store listed its 8x8 aluminum-frame polycarbonate greenhouse at $589.99, roughly $310–370 less than this cedar 8x8. Plan for a staggered delivery — Veikous says the 8x8 ships in four packages that may not arrive at the same time, so check every box is in before you start building.

How to choose a cedar greenhouse kit

1. 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.
2. 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.
3. Compare windows and vents, not “solid cedar” claims. Both BlueWish and Veikous pair a cedar frame with polycarbonate panels; “solid cedar” on a listing describes the lumber, not solid walls. Veikous adds a side window on every size, which helps cross-ventilation in summer. If a panel ever cracks, replacement twin-wall comes in the same thicknesses — see our greenhouse panels guide.
4. 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.
5. Don’t skip the foundation. Wood-frame kits carry more weight than aluminum ones — see our greenhouse foundation guide before ordering.
