Simple devices which open and close roof vents automatically for you according to temperature. They contain an industrial wax‐like substance inside a cylinder which expands and contracts with according to the temperature and pushes or pulls a rod that opens or closes the automatically. The temperature at which they open and close can be adjusted by hand but you cannot manually open the vent. The cylinder containing the wax‐like substance is a consumable item but typically lasts a number of years and can be easily replaced. Generally in windy weather automatic openers are cooled down by the wind and so close the vents.

Don’t be fooled by the name, a seedbed can fulfil many purposes. First and foremost it provides a comfortable surface on which to pot up and tend to plants. You can use it to display plants on and it gains you additional space in the Greenhouse. A seedbed can be fitted with capillary matting to assist even water distribution among your pot plants or you can fit an electric thermostatically controlled heated mat in it to make a propagator.
Multiple units can be fitted.  They can be fitted along the full length of the side and/or across the full width of the gable ends.  Each seedbed frame is made from aluminium in the same colour as your Greenhouse and the tongued and grooved plastic panels which make up the bottom are white.  The seedbed is 500mm wide

The Janssens shelf is an aluminium section 115mm wide. It is useful for small pot plants and odds and ends like gloves, secateurs and other small odds and ends. A shelf also adds to the already powerful strength of the Greenhouse. It is supplied in the same colour as your Greenhouse.

Janssens’ attractive shade screen comes in 3m lengths and is fitted like a curtain, it will slide allowing you to pull it over exactly the area you want to give shade to and push it away when you want more light.  Equally useful for shade loving plants that do not want direct sunlight or customers who want to enjoy sitting and reading a paper in the shade!
