                UNRIVALLED VENTILATION
Greenhouses are very prone to overheating so we have made sure that the Harrod Superior Greenhouse range has more ventilation included that any other model on the market! The total ventilation footprint is the same area as a third of the greenhouse floor space which is quite a challenge and one which none of our competition manages to achieve. This required the production of unique roof vents twice as large as standard models in order to achieve this.
A top quality greenhouse will also provide excellent air circulation to prevent moist stagnant air encouraging disease. The more air you have above your seedlings the better the growth as temperatures fluctuate less.
The climate is automatically controlled by a combination of double/triple vents, Bayliss autovents and at least two
5 bladed louvre vents ensuring fresh air can circulate
and cool. Bayliss autovents are included in each of our models as they are well known for being super sensitive to temperature change. Controlling the internal greenhouse temperature far quicker and more accurately than we ever could, even the slightest overhead cloud will quickly begin to close the roof autovents. The roof vents remain shut in strong winds thanks to the double spring that holds them shut. Alternatively you can disconnect the autovent for periods of forecasted high wind using the unique bracket to lock the roof vent safely shut. A 6ft x 8ft greenhouse comes with two large double roof vents controlled by autovents and two 5 blade louvres vents for air circulation. This level of ventilation is normally applicable for a greenhouse twice this size!
Diagram (B) right shows how the Louvres allow fresh air to circulate and cool the greenhouse.
