Our Planta Greenhouses Review
Planta is the kit brand that answers the question most of the lane dodges: what is it rated to carry. 75 psf of snow and 65 mph of wind is a real engineered number, on a galvanised steel frame with 6 mm double-wall polycarbonate and a 10-year warranty, at $2,250 to $6,100 for the kit. If you garden anywhere with real winter, that rating matters more than anything else on the spec sheet. What it is not is a glasshouse: polycarbonate diffuses light and the bell shape is functional rather than pretty.
Sungrow Gen II kit prices read from plantagreenhouses.com in August 2026: Compact 10x6.5 at $2,250, Urban 10x13 at $3,000, and up through the 20, 26, 32 and 39 foot lengths to $6,100. Kit price only. The base, foundation and assembly are extra and are usually the difference between the kit price and the project price.

Strengths & Considerations
Strengths
- +Publishes an engineered rating: 75 psf snow load and 65 mph wind, which is a number you can check against your site rather than a claim.
- +6 mm double-wall polycarbonate on a galvanised steel frame, which is a heavier build than most kits at this price.
- +10-year warranty covering the metal and polycarbonate against rated loads and age-related corrosion.
Watch Out For
- −Polycarbonate diffuses light rather than transmitting it clearly, so it is not a glasshouse substitute if you want the look.
- −The 8 ft roof height and bell shape suit snow shedding but are a specific aesthetic that will not suit every garden.
- −Kit prices exclude the base, which on a structure this size is not a trivial cost.
Before You Buy: Confirm These
These are Planta Greenhouses's own documented terms and open questions, not our own test results. Confirm the specifics in writing before you order.
- ?The 75 psf rating applies to the structure as engineered and assembled. It is not a promise about a kit built on an inadequate base.
- ?Check the rating against your local snow load requirement, not against the marketing description of six feet of light snow.
- ?Budget the base and foundation separately. The kit price is not the project price.
- ?Confirm what the 10-year warranty excludes. Rated loads and corrosion are covered; assembly error will not be.
Alternatives to Compare
Palram Applications (Canopia)
mid rangeA sensible pick for budget-minded and first-time growers who want an inexpensive, retail-available kit and are comfortable with DIY assembly and modest insulation. Buyers in windy or snowy areas, or anyone wanting long-term durability and warmth, should either upgrade to a twin-wall model like Mythos or Glory or look at a sturdier brand; do not treat the thin single-wall entry kits as a permanent, storm-proof structure.
Solexx
mid rangeA strong pick for a serious hobby grower in a cold or windy climate who values insulation, even diffused light, and hail resistance over a clear-glass look, and who is comfortable paying more than a budget kit. Skip it if you want to see through your greenhouse walls, need maximum winter light for light-hungry plants, or are shopping purely on price, where a Palram or Rion kit will cost less.

Why Consider Planta Greenhouses?
Added 2026-08-17 after the brand-gap report measured 20 weekly US searches with no page here, against 5 for Canopia, the quietest brand we publish. The reason it earns a page is the published load rating, which almost nothing else in the kit lane states.

Methodology
Brand verdicts are based on buyer fit, build quality, support path, price pressure, and the risks that tend to show up after delivery. A strong reply from a manufacturer can improve factual clarity, but it does not improve placement.
If support coverage, warranty language, or dealer access are thin, we would rather say that plainly than hide it behind marketing copy.
