29 Jan Greenhouse polythene in Kenya
The 2 aspects of greenhouse polythene
The two aspects to greenhouse polythene in Kenya type and color selection are; light and heat. Light as a factor of the amount of Ultra- violet (UV) radiation your greenhouse is receiving, heat the level of Infra-red (IR) light coming through.
- Your light factor; When do I use clear polythene, and when do I use yellow polythene? A mono color rose grower likely uses yellow greenhouse polythene. This is because it has a more intense UV block treatment, thus allows less UV light in so as to optimise the color intensity of the mono color rose crop. Greenhouse vegetables enjoy high UV for photosynthesis. The more food your crop makes, the better the yield. Clear greenhouse polythene in Kenya allows much more UV light for your greenhouse crop. Bi-color flowers too require higher UV for a broader flower color spectrum.
2. Your heat factor; clear or yellow polythene type 205 is better if your greenhouse is in a warm area. Type 205 greenhouse polythene in Kenya is without IR treatment, thus retains less heat in the greenhouse. Its ideal for hot arid climates, warm Savannah or warm coastal regions. Type 504 greenhouse polythene will suffice pretty well in cool locations because with its IR treatment, it retains much heat. This is great for cool high altitude areas in Kenya. Again, if the variance between your night and day temperature is wide, 504 is recommended. This is because it has less dripping (formation of water droplets/ dew) on the inside. This interferes with proper light distribution in the greenhouse.
So next time you procure your greenhouse polythene, remember this attributes.
