Palram Canopia Mythos 6x4 Silver Polycarbonate Greenhouse (1.85m x 1.26m)

The Palram Canopia Mythos 6x4 (701636) is a silver-framed polycarbonate apex greenhouse measuring 1.85m x 1.26m that's roughly 2.3 square metres of growing space. For a compact garden it delivers a serious amount of usable floor and staging area without taking over the lawn. The apex roof sheds rainwater efficiently and the integrated gutters collect it for reuse.

The frame is rust-resistant aluminium with a galvanised steel perimeter base. The 4mm twin-wall polycarbonate panels are shatterproof and fracture-proof transmitting 82% of light while blocking harmful UV rays. The structure is wind tested to 90km/h and snow-load tested to 75kg/m². Panels slide into pre-cut uniform profiles making assembly straightforward.

A single manually-opened roof vent lets you regulate temperature. No staging is included but Palram Canopia shelving is available separately. The 1.85m x 1.26m footprint fits two standard grow bags on the floor with room for pots of tomatoes, peppers or cucumbers alongside.

A 5-year limited warranty backs the whole structure. The door fits left or right-hand opening and has a latch with padlock fixing. Maintenance-free materials and free UK delivery make this a practical first greenhouse for any small garden.

The Mythos uses a silver aluminium extrusion frame with a galvanised steel perimeter base for ground-level rigidity. The 4mm twin-wall polycarbonate panels slide into pre-cut frame channels no drilling through glazing is needed. Twin-wall construction means two skins of polycarbonate with an air gap between them which improves heat retention over single-skin glazing. The apex roof pitch sheds rain quickly and feeds the integrated gutters. The structure is wind tested to 90km/h and snow-load rated to 75kg/m². The manually-operated roof vent is hinged at the ridge and opens outward to release heat and moisture.

The frame is rust-resistant aluminium with a silver finish. The perimeter base is galvanised steel. All glazing panels are 4mm twin-wall polycarbonate shatterproof, fracture-proof and fully UV protected. Brackets and fasteners used in optional accessories are galvanised steel. No timber is used anywhere in the structure.

No floor is supplied with this greenhouse. It must be fixed to a solid level base a concrete slab or level paving is ideal. You need to prepare and level the ground yourself before building. The galvanised steel perimeter base sits on top of your prepared surface. An optional anchor kit is available separately for additional wind security.

The Mythos arrives flat-packed for DIY assembly. Pre-cut panels slide into uniform aluminium frame profiles which Palram Canopia describe as incredibly easy to put together. Two people are recommended one to hold sections while the other fixes them. No assembly time is stated by the manufacturer. Professional installation is available through the merchant if preferred. Check that all fixings and instructions are present before you start.

The 1.85m x 1.26m floor fits two standard grow bags side by side that's space for six tomato or pepper plants. Add a third grow bag across the end for cucumbers or aubergines. In spring use the floor and any staging for seed trays and plug plants. In summer the height of 2080mm at the ridge gives climbing tomatoes room to grow tall. In winter the twin-wall polycarbonate holds enough warmth to overwinter tender perennials, citrus in pots and dahlia tubers. Optional Palram Canopia shelving adds a second growing tier above floor level.

Palram Canopia state this greenhouse is completely maintenance free. Wipe the polycarbonate panels with a soft cloth and mild soapy water once or twice a year to keep light transmission at its best. Check the roof vent mechanism each spring and clear the integrated gutters of debris in autumn. No timber treatment is required as the frame is aluminium.

At 1.85m x 1.26m this greenhouse fits into a corner or along a fence line in most small gardens. Leave at least 600mm clearance on the door side to open it fully and allow access. The roof vent opens upward so no side clearance is needed for it. The compact footprint still gives you two full grow bags on the floor plus wall-mounted shelving above so usable growing space is greater than the floor area suggests.
