The water outlet of planting basin on the circulation water path department is equipped with the check dam, and the check dam can guarantee that every layer of planting basin remains the nutrient solution of certain concentration all the time, and the water pump need not incessantly to move and keeps the circulation of water path, and the water pump liquid level also can satisfy the normal growth demand of plant when not moving, and the water pump intermittent type moves, has practiced thrift the energy, has reduced the water pump noise.

4. The filter is arranged at the top of the retaining dam, so that impurities such as rotten roots and algae in the circulating nutrient solution can be filtered, and the impurities cannot flow into a planting basin at the next layer, so that the water way is prevented from being blocked.

5. Through setting up EC concentration sensor in the delivery port of water pump, set up level sensor in the water tank, the plant machine can remind the user to add the nutrient solution according to liquid level and nutrient solution concentration automation to the suggestion user should add how much and the concentration of nutrient solution, has promoted user experience and has felt.

The foregoing embodiments have been provided for the purpose of illustrating the general principles of the present application, and are not meant to limit the scope of the utility model, but to limit the scope of the utility model.
