These 6x4 greenhouses from palram called the harmony greenhouse is a fantastically designed garden building. Make it the year you start to enjoy the garden and grow vegetables and plants all year round with these 6x4 greenhouses. The amazing design means that an aluminium frame is used to assure a solid build that is long lasting. The frame is rust resistant and is powder coated with a green pigment for increased attractiveness in the garden. The clear polycarbonate panels are extremely durable and allow in 90% light but blocks 99% of harmful uv rays, preventing dis colouring. The 6x4 greenhouses fit into the corners of gardens easily and in smaller gardens but gives a lot of growing space. The aluminium floor base prevents rusting to the frame and stops rain water from seeping in. To control the air inside the 6x4 greenhouses a roof vent is positioned to enable fresh air in when required. Another great thing is the side gutter that promotes recycling of rain water instead of us...
