A single-pan hydroponic system is a simple and cost-effective way to grow vegetables in a greenhouse. It involves using a single container or tray filled with an inert growing medium, such as perlite or vermiculite, and a nutrient solution that is circulated through the system.
A customizable hydroponic system for vegetables and flowers is a great way to grow fresh produce and beautiful blooms in a controlled environment. Here are the steps to create a basic system:
Materials needed:

Steps:
1.Choose a hydroponic tray or container that fits your space and needs. This can be anything from a small plastic container to a large metal tray.
2.Add a layer of hydroponic growing medium to the bottom of the tray. This will provide a place for the roots to grow and absorb nutrients.
3.Set up a water pump and tubing system to deliver water and nutrient solution to the plants. The pump should be placed in a reservoir of water and nutrient solution, with tubing leading to the hydroponic tray.
4.Install an air pump and air stones to oxygenate the water and nutrient solution. This will help the plants grow healthy roots.
5.Plant seeds or seedlings in the hydroponic growing medium. Make sure to space them out properly and keep them moist.
6.Set up a light source for the plants. This can be natural light or LED grow lights. Make sure the plants receive enough light for their specific needs.
7.Monitor the water and nutrient levels regularly, and adjust as needed. Check the pH level of the solution to make sure it's within the optimal range for the plants.
8.Harvest the vegetables and flowers when they are ready. Enjoy fresh, healthy produce and beautiful blooms!
With these basic steps, you can create a customizable hydroponic system for vegetables and flowers that works for your specific needs and space.

Film greenhouses are constructed using thin film as a covering material.The main structure of this kind of greenhouse is not only simple and practical, but also the cost is relatively low, which is very suitable for the cultivation of vegetables and other crops. The top of the film greenhouse can usually be covered by double-arch double-film or single-film, while the surrounding can be covered by different materials such as double-film, single-film, PC board or glass according to the needs, so as to realize the automatic control of the greenhouse environment. Its high light transmittance, good thermal insulation performance and strong aging resistance make the film greenhouse provide a stable and suitable growth environment for vegetables, thus having a positive impact on the growth and yield of crops.

Compared with the traditional glass greenhouse, it has the following advantages:

1. Low cost: Compared with traditional glass greenhouses, film greenhouses are less expensive to build and operate, making them ideal for small and medium-sized farms and home gardens.
2. Flexibility: The installation and disassembly of the film greenhouse is relatively simple, and the position and size can be easily adjusted according to the needs.
3. Energy-saving and environmental protection: The film material has good light transmittance, which can effectively utilize natural light and reduce the demand for artificial lighting. At the same time, the thermal insulation of the film helps to reduce energy consumption.
4. Strong adaptability: Film greenhouse can be used in different climatic conditions, whether in cold winter or hot summer, it can provide a suitable growth environment for plants.
5. Prevent pests and diseases: Film greenhouse can effectively isolate external pests and diseases, reduce the use of pesticides, and help to produce safer and healthier agricultural products

In order to achieve efficient and accurate control of plant growth environment, film greenhouse needs to be equipped with a series of facilities and systems. Below are some of the main supporting facilities.
