Palram Canopia Mythos 6x6 Silver Polycarbonate Greenhouse (1.85m x 1.86m)

The Palram Canopia Mythos 6x6 (701630) is a square apex greenhouse with a 1.85m x 1.86m footprint roughly 3.4 square metres of growing space. That is a practical amount for a compact garden. The apex roof gives good headroom at 2080mm at the ridge and 1240mm at the eaves.

The rust-resistant aluminium frame sits on a galvanised steel perimeter base built to handle UK weather. 4mm twin-wall polycarbonate panels transmit 82% of available light while blocking harmful UV rays. The panels are shatterproof and fracture-proof. Wind resistance is rated to 90km/h and snow load tested to 75kg per square metre.

A manually-opened roof vent lets you regulate temperature without fuss. Integrated rain gutters collect runoff for watering a practical touch. No staging is included but Palram Canopia shelving is available separately. Realistically you can grow tomatoes, peppers, cucumbers and overwinter tender plants in a space this size.

The 5-year limited warranty and maintenance-free build make this a solid long-term buy. The single door fits left or right-hand opening. Panels slide into pre-cut profiles for straightforward DIY assembly. Available in silver or grey frames.

The Mythos uses an extruded aluminium frame with a galvanised steel perimeter base that resists rust without any treatment. The 4mm twin-wall polycarbonate panels are pre-cut to uniform profiles and slide into the frame channels no drilling through the glazing is needed. The apex roof pitch sheds rainwater efficiently into the integrated gutters. The polycarbonate construction is rated to withstand winds of 90km/h and snow loads of 75kg per square metre. The single manually-operated roof vent is hinged at the ridge and held open by a stay arm to regulate temperature.

The frame is extruded aluminium with a UV-treated finish. The base is galvanised steel. All glazing panels are 4mm twin-wall polycarbonate shatterproof, fracture-proof and UV protected on both surfaces. The panels will not discolour or fade in sunlight according to the manufacturer.

No floor is included with this greenhouse. It must be fixed to a solid, level base a concrete slab or firm paving is recommended. You need to prepare and lay the base yourself before assembly. No base or flooring is supplied with the greenhouse.

The Mythos 6x6 arrives flat packed for DIY assembly. Polycarbonate panels are pre-cut with uniform profiles and slide into the aluminium frame channels. No specialist tools are needed. Two people will make the job easier and safer. Most builders complete it in a few hours. All fixings are included and assembly instructions are provided with the kit.

The 1.85m x 1.85m floor gives you roughly 3.4 square metres of growing space. You can fit two standard grow bags on the floor with room to move that is around six tomato or pepper plants. Add optional staging along one side and you gain bench space for seed trays and pot-grown plants. In spring use it for sowing seeds and hardening off young plants. In summer grow tomatoes, cucumbers and peppers. In autumn and winter use it to overwinter tender perennials, fuchsias and citrus plants that would not survive a UK frost outside.

The Palram Canopia Mythos is described as completely maintenance free. The aluminium frame needs no painting or treating. Wipe down the polycarbonate panels with a soft cloth and mild soapy water to keep light transmission at its best. Check the roof vent mechanism works freely each season. Clear the integrated gutters of debris in autumn.

At 1.85m x 1.85m this greenhouse suits a patio corner or the end of a narrow garden. You need roughly 600mm clearance on the door side to open it fully and stand comfortably. The apex roof keeps the footprint square so it fits against a fence on two sides. Despite the compact floor area you gain usable bench space on both sides if you add optional staging shelves.
