Verdict

Palram Essence 8x12: excellent, 9.0/10

The Essence is the best buy among the 8x12 kits: 4 mm twin-wall polycarbonate on every side, double doors 47 in wide with a low ramp, two roof vents, gutters and a galvanized steel base, all for $1,899 at Planet Greenhouse on November 12, 2026. It is a three-season greenhouse more than a snow fortress (15 lb/ft², 56 mph), and the warranty is five years.

Buy it if

  • You want a real walk-in greenhouse and a budget under $2,000
  • You need wide, step-free doors
  • You garden from early spring to late fall

Skip it if

  • You get heavy snow every winter (look at the Arrow or the Glory)
  • You want automatic vents out of the box

The sweet spot of the Palram range

Palram-Canopia makes several 8x12 kits, and this is the one we would buy with our own money on a normal budget. For $1,899 you get 4 mm twin-wall polycarbonate on the roof and all four walls, not just the roof. That matters on a cold spring night: twin-wall walls hold heat that single-layer clear walls lose. Light transmission is 82% per the dealer's spec table, diffused.

The frame is rust-resistant aluminum, and the peak sits at 91 in (7 ft 7 in) with a 48.6 in eave. Comfortable in the middle, a little lower at the bench line.

Doors you will love

The double doors are the detail that wins people over: 75 in high and 47 in wide, per Canopia, lockable, with a low threshold ramp. A wheelbarrow rolls straight in, so does a wheelchair, and moving a 20-gallon pot in spring stops being a two-person job. Most budget kits have one narrow door; the Mythos 6x8, for comparison, has a 22.2 in opening.

Snow, wind and where to put it

Canopia says the Essence was "tested to withstand" 15 lb/ft² of snow and handles winds up to 56 mph. Those are three-season numbers. In a mild or moderate climate that is plenty; in heavy-snow regions you would want the 32 to 38 psf of the YourGreenhouses tunnels. Put it somewhere sheltered from the prevailing wind and on a level base. The galvanized steel base is included, per Planet Greenhouse.

Price and warranty

Planet Greenhouse, the US dealer we link to, listed it at $1,899 on November 12, 2026, with free curbside freight to the 48 contiguous states. Palram-Canopia covers it with a 5-year limited warranty. It is a DIY kit; Palram-Canopia says no special tools are needed, and two people make it a much happier weekend.

The good and the catch

What we like, and what to know

  • $1,899 for a 95 sq ft walk-in kit with twin-wall panels all round
  • Double doors, 75 in high by 47 in wide, with a ramp for wheelbarrows and wheelchairs
  • Two manually adjustable roof vents
  • Galvanized steel base and rain gutters included
  • 7 ft 7 in at the peak

The catch: Its 15 lb/ft² snow rating and 56 mph wind rating are fine for mild winters, not for heavy snow country. The warranty is five years.

Where these figures come from

Palram Essence 8x12: questions

Is the Palram Essence 8x12 good for winter?
For mild winters, yes: its 4 mm twin-wall panels insulate better than clear single-layer walls. Its published ratings (15 lb/ft² of snow, 56 mph of wind) are not meant for heavy snow regions.
Does the Palram Essence come with a base?
Yes. Planet Greenhouse lists a galvanized steel base as included.
How wide are the Essence doors?
Canopia lists double doors 75 in high and 47 in wide, with a low ramp-style threshold for wheelbarrows and wheelchairs.
Essence or Balance?
The Essence for most people: it costs $600 less and has twin-wall panels on the walls too. The Balance has clear walls, a green frame and slightly better published ratings in its feature list.
