Rank #2 in Best Greenhouse 2026: The Weight Field Is Three Numbers
Outsunny 6 x 8ft Polycarbonate Greenhouse, Walk-In with Slide Door, Dark Green
Price and rating as shown on Amazon when we collected them. Both change.
The Outsunny 6 x 8 polycarbonate greenhouse is the cheapest real structure in this ranking: £241.39 for an aluminium frame with polycarbonate panels, weighing 34.5kg.
It takes second because 577 ratings is a solid sample and because the same model in grey costs £85.60 more — but its 3.7 stars with 19 per cent one-star is the weakest record here.

Questions people ask
Why is the green one cheaper than the grey?
They are the same structure on two listings: the grey carries £326.99 and the green £241.39, with the same 577 ratings behind both.
Will it stand up to wind?
Polycarbonate panels in an aluminium frame are the right design, but the panel thickness is not published, so the wind rating cannot be checked.
How long does assembly take?
Days rather than hours, according to owners, though one calls it fiddly and worth it.
Do I need a base?
A level base is essential for a structure of this size and weight.
Why is it second?
Because it is the cheapest real greenhouse here and the record is the weakest.
How many ratings does it have?
577 at the time of collection, averaging 3.7 stars, with 47 per cent five-star and 19 per cent one-star.
