This isn't going to be for everyone, but I've just saved about £100 off the B&Q price for this little green house. I used the new customer code to get £10 off the overall total bringing it down to £178.50 delivered. It might be useful for someone out there. You can also get the aluminium version for about £157.50 delivered so if you don't care about the colour it's even cheaper! It gets pretty good reviews too.
Simple and elegant, the New Harmony range from Palram features unique crystal clear unbreakable polycarbonate panels and heavy duty rust resistant powder coated green aluminium frame. The polycarbonate glazing is lightweight, virtually unbreakable and has no sharp edges. These features create a safe environment for the whole family. The panels have a slide and lock system that firmly holds the panels in place from all sides. The 6x4 greenhouse has a hinged lockable door with magnetic catch, opening roof vent and galvanised powder coated steel base included. The greenhouse comes with easy to follow instructions and is conveniently packed. Everything you need to help the family growing. A wide range of Palram accessories are also available, helping you make the most of your greenhouse.
