Plants which are dry at the roots or drying out are therefore more at risk than plants which have adequate moisture at the roots. This Louvre Window Kit consists of the operating components for a six-bladed louvre, complete with all the fixings required for fitting to an aluminium greenhouse. A Louvre Window placed low in the sides or end of any greenhouse will help improve airflow and aid summer ventilation; both desirable traits when growing in a greenhouse. Open all doors and vents on sunny days. These can be left open at night if the temperature remains high Louvre windows allow the cooler air during the summer months to enter the greenhouse at the lowest possible point. This in turn pushes the warmer air out of the open roof vent.
Polyethylene mesh or netting (shade netting): is usually placed inside the glasshouse and fixed with clips. External fitting is better but harder to arrange. This is a cheaper option than blinds. The plastic is likely to biodegrade over a number of years but is not expensive to replace.

Keep your greenhouse cool and your plants healthy with our selection of greenhouse vent systems, auto vent openers and accessories. Good ventilation lets in the fresh air that plants need for pollination and growth. It also reduces humidity and makes the greenhouse less inviting to pests that otherwise might turn it into their new home. Be alert for signs that shading and ventilation are required; sun-flag (partial collapse), leaf scorch, desiccation of tender young plants and shoots Greenhouse Megastore offers a variety of airflow solutions for growing structures of all sizes, including roof and side vents, louver windows, poly side venting, end wall venting and aluminum shutters. Our products range from heavy-duty to the most economical. Whether you need a complete greenhouse ventilation kit or a new automatic greenhouse vent opener, our greenhouse experts can help you find the right product.
Leaf temperature is mainly controlled by movement of water through the plant and out through the leaf surfaces in the form of transpiration – this process has a cooling effect on the leaves.
As suggested a louvre window should be fitted near the base of the greenhouse rather than higher up. It will fit between the upright glazing bars and will replace a piece of glass. Detailed fitting instructions are supplied.With horticultural glass, you would simply replace a panel of glass with a louvre panel. With long pane toughened glass you would normally be supplied with one additional panel cut short to accommodate a louvre if required. Fitting a second louvre may involve buying an additional panel of glass. This particular photograph of a louvre is 18ins x 24ins fitted with toughened glass in the blades. It is used as a guide photo only. Delivery
