Description

Grekkon Limited’s greenhouse polythene cover is a special plastic film that covers a greenhouse structure to create the greenhouse effect. This is by separating the outside environment from inside to create a controlled warm micro-environment within. Our greenhouse polythene sheeting is specifically manufactured for crop production in every technical way. This includes; the choice of colors, paper thickness, anti-UV block treatment, and the anti-drip qualities. The choice of structure, which is a wooden or a metallic greenhouse has no effect on the type of greenhouse polythene paper. Similarly, the greenhouse design; vented type or tunnel type will not affect the paper color chosen. Your choice of greenhouse polythene cover is determined by the crop grown only

How To Select The Right Greenhouse Cover For Your Crop

Crop type

Different crop types have different light requirements

1.1. Fruiting type. Tomato, pepper, strawberry, cucumber require more light to make food to support fruiting. Have a clear polythene greenhouse cover for more light

1.2. Vegetative crops. Leafy vegetables, herbs and spices will produce well in less light than in 1.1. above. Clear or yellow polythene works

1.2. Mono color flowers. Yellow polythene intensifies petal color for mono color roses and other flowers. This increases their marketability

1.4. Bi or multi color flowers. Construct with clear polythene for with this crop

2. Disease incidence

Crops such as; tomato, pepper, strawberry, cucumber, roses, carnations, chrysanthemums and many others are susceptible to blight. This is when moisture remains on their leaves. For such, your greenhouse polythene sheet will have anti-drip treatment. Anti drip treatment prevents dew droplets from forming on the paper when moisture condenses. These drops cause fungal infections when they drip on the leaf surface of the crop. Anti-drip treatment is available for both clear and yellow paper types

3. Budget

The anti-drip treated greenhouse polythene paper more expensive. However, it saves the grower more money, as a result of less fungicide application

The paper choice applies to any greenhouse structure; wooden or steel. This is true also for any greenhouse size

How to Keep Your Greenhouse Polythene Tight

Spread out the paper on the greenhouse structure early in the morning or late in the evening when he temperature is below 20 degrees celcius. If it’s too hot, the paper will tear on contraction when it gets cold. If it’s too cold, the paper will sag when the temperature rises
Roll it or pull it from one end to the next frame or runner and secure it with a profile and wiggle wire. Then stretch it again for this point to the next and so on
Avoid covering in the afternoon when it is very windy as this will cause the paper to tear
