In most cases, a greenhouse provides an environment where heat and humidity can be maintained, making it possible to grow crops, flowers, and other plants that normally only grow in warm weather, even during winter. If you have enough time and budgets in your project, a glass greenhouse or a solar greenhouse would be a better choice in agriculture. However, if you would have some limitation in your project, plastic greenhouse would be another cost-effective greenhouse in applications today. Are you ready to start building your plastic greenhouse now?
First of all, the material of your greenhouse will be subjected to quite a lot of extreme conditions. It may need to endure torrential rains, strong winds, or heavy snowfall. Even direct sunlight isn’t exactly favorable to all plastics since a lot of them can turn brittle with constant UV exposure. A tear on your greenhouse plastic can drastically reduce its effectivity, so investing in a high-quality plastic sheet made with the appropriate material will save you from a lot of future headaches. In general, polyethylene is cheap, accessible, and easy to repair in a plastic greenhouse. In the current market, there are several different grades and copolymers of polyethylene for your choice.
Secondly, just like a solar greenhouse, a plastic greenhouse also needs sunlight to reach the plants so they can go through photosynthesis. This means that you would want as much sunlight as possible to go through your greenhouse walls. Transparency typically is not considered much of an issue when using clear fiberglass or glass panels but finding the right balance between transparency and thickness can be tricky if you’re using plastic sheets.
Thirdly, depending on outdoor conditions, there could be several factors that could reduce the effectivity of your greenhouse in applications. For example, on cold days, the imbalance between the cold outer surface and the warm interior of a greenhouse could result in condensation forming on the inner surface of your plastic sheet. These condensate droplets could end up falling on your plants, disturbing the delicate ecosystem that you’ve so carefully crafted by promoting the growth of mildew. Fortunately, some plastics are naturally equipped to prevent this from happening. Plastic with a hydrophilic radical, such as -COOH (or carboxylic acid) helps prevent condensates from dropping onto the plants, instead retaining them on the surface to evaporate naturally. On the other hand, you would want to avoid plastics with hydrophobic radicals such as -CH groups, since they will repel condensate droplets.
