Quick Answer: The Yardistry Meridian 6.7’ x 6’ is the best entry point into this line — a kiln-dried cedar frame with double-wall polycarbonate windows, priced around $1,699.99-$1,751.99 depending on retailer. Need more growing floor? The 6.7’ x 7.8’ (roughly $2,189-$2,998) and the largest 6.7’ x 9.7’ (roughly $1,899.99-$3,699, heavily promotion-dependent) scale up the exact same cedar base-wall design, built-in shelving, and automatic roof vent.

Yardistry didn’t start out building greenhouses. For nearly 20 years the company built its name on cedar gazebo kits, later expanding into pergolas, pavilions, and louvered rooms, per Yardistry’s own site — the Meridian greenhouse line is a newer extension of that same outdoor-structure business, closer in spirit to this site’s Backyard Discovery roundup (a swing-set company’s greenhouse line) than to a dedicated greenhouse maker like Palram or Riga.

1. Yardistry Meridian 6.7’ x 6’ — Best Entry Point

Yardistry Meridian 6.7' x 6' Greenhouse

Best entry point · 6.7' x 6' · ~$1,699.99-$1,751.99
  • 100% kiln-dried, pre-stained cedar lumber, pre-cut and pre-drilled for assembly.
  • Double-wall polycarbonate windows for insulation and UV filtering.
  • Heat-sensitive automatic roof vent opener plus a louvered base-wall vent for passive air intake.
  • 32-inch cedar base walls with a built-in 16-inch lower shelf and 8-inch upper shelf per side.

This is the smallest Meridian size, but it isn’t a stripped-down version — it carries the exact same cedar grade, polycarbonate thickness, and built-in base-wall shelving as the larger two sizes. What you’re trading for the lower price is floor space, not construction quality, which makes it the size worth defaulting to unless you already know you need more growing room.

Compared to this site’s cedar-frame kit pick, the Meridian’s automatic heat-sensitive vent is a genuine step up — BlueWish and Veikous both rely on manual venting at this price tier.

2. Yardistry Meridian 6.7’ x 7.8’ — Best Mid-Size

Yardistry Meridian 6.7' x 7.8' Greenhouse

Best mid-size · 6.7' x 7.8' · ~$2,189-$2,998
  • Same cedar lumber grade, polycarbonate thickness, and automatic vent system as the 6.7' x 6'.
  • Roughly 30% more floor area than the smallest size, enough for a center aisle plus benches on both sides.
  • Sold through Costco (sometimes bundled under a Costco-specific model number) in addition to Walmart and the brand's own site.

The price gap between this size and the smallest Meridian varies more by which retailer currently has it in stock than by a predictable per-square-foot markup — Walmart listings have shown this size anywhere from roughly $2,189 up to $2,998. That makes it worth checking Yardistry’s own site, Walmart, and Costco side by side before buying rather than assuming any one retailer has the better price on a given week.

3. Yardistry Meridian 6.7’ x 9.7’ — Best for Max Growing Floor

Yardistry Meridian 6.7' x 9.7' Greenhouse

Best for max growing floor · 6.7' x 9.7' · ~$1,899.99-$3,699
  • Largest size in the Meridian line, with the same cedar base-wall shelving and automatic vent system as the two smaller sizes.
  • List price around $2,799.99 at Yardistry's own site, frequently discounted to roughly $1,899.99.
  • Priced up to $3,699 at some Canadian retailers (Rona) — confirm current pricing before ordering.

This is the one size in the line where the sale price genuinely swings below the mid-size model’s typical price — a real example of why checking current promotions matters more than trusting a list price on any wood-frame greenhouse this large. If you have the yard space and catch it on sale, it’s the best per-square-foot value in the Meridian lineup; at full list price, it’s priced closest to this site’s best greenhouse kit pillar picks in the aluminum-and-polycarbonate category instead.

How to choose a Yardistry Meridian size

  1. Default to the 6.7’ x 6’ unless you know you need more room. It carries identical materials and warranty to the larger sizes — the price difference buys floor space, not quality.
  2. Check Yardistry’s own site, Walmart, and Costco before buying the mid or large size. Prices for the same size have varied by several hundred dollars across retailers in this comparison.
  3. Budget for a foundation separately. Like any structure this size, a level pad isn’t included — see our greenhouse foundation guide before you commit.
  4. Compare against Backyard Discovery if you want electricity built in. Yardistry’s base-wall vent and shelving are genuinely strong, but unlike Backyard Discovery’s PowerPort-equipped line, no Meridian size includes onboard electrical outlets.
  5. Weigh cedar against aluminum. Cedar resists rot without chemical treatment and holds warmth overnight better than bare aluminum, at the cost of more upkeep than this site’s Palram aluminum-and-polycarbonate picks.

The bottom line

The Yardistry Meridian 6.7’ x 6’ is the best way into this line for most buyers — real kiln-dried cedar construction, double-wall polycarbonate, an automatic heat-sensitive vent, and built-in base-wall shelving, all backed by a 5-year warranty on both lumber and panels. Need more growing floor? The 6.7’ x 7.8’ and 6.7’ x 9.7’ scale up the identical materials and features, though pricing on both swings more by retailer and promotion than by a predictable size curve — worth a quick price check across Yardistry’s own site, Walmart, Tractor Supply, and Costco before you order. Whichever size you pick, know what you’re buying: a nearly-20-year gazebo and pergola company’s greenhouse line, not a dedicated greenhouse manufacturer’s — genuinely solid cedar-structure engineering, just not Yardistry’s original specialty.
