Expertly built in Europe, this greenhouse heater uses Piezo ignition, making it incredibly easy to operate, reliable and energy efficient.

Description
Impeccably designed, incredibly easy to assemble, and providing ideal growing conditions for plants, it's no wonder the high-spec 8' x 12' Palram Rion Grand Gardener Greenhouse (2.4m x 3.6m) is considered the gardener's best friend.
Supported by a green resin frame with pin and lock connectors, this 8x12 greenhouse combines light-diffusing 4mm twin-wall polycarbonate roof panels and crystal-clear 0.7mm polycarbonate side panels to provide 90% light transmission.
Both types of polycarbonate glazing are completely UV-protected, while the high-impact roof panels promote an even temperature by increasing thermal insulation and reducing extreme sunlight exposure. This means plants enjoy perfect growing conditions, the gardener remains safe from harmful UV-rays and the panels won't discolour or fade in the sun. The roof's barn-shaped design provides increased headroom and ensures highly effective rainwater runoff.
Shatterproof, fracture-proof and completely resistant to rust, this polycarbonate greenhouse is wind resistant to 90km/ hr (56ml/ hr) and snow-load tested to 75kg/ m² (15.4lbs/ ft²). With its rubber sealing strips, for enhanced insulation, and a reinforcement cable to maximise structural stability, this premium greenhouse provides both plants and garden equipment with outstanding weatherproof protection.
Easy access is gained through wide double doors, fitted with a convenient handle holder to keep them firmly in position and maintain the exceptional weatherproof protection. This polycarbonate greenhouse features 2 manually-opened roof vents too, allowing the temperature to be regulated for the benefit of plants and gardeners alike.
Supplied with an excellent 7-year limited warranty and completely maintenance free, this beautiful greenhouse is incredibly easy to assemble, with no tools required. Designed without a floor, it should be fixed to a solid, level base.
This greenhouse for sale is available in a range of sizes. A portable fan greenhouse heater with digital thermostat is also available to buy as an invaluable greenhouse accessory.
