Engineer Vi Toan Nghia designed the automatic plant care machine based on an integrated technique inside the controller, the most important element of the machine. With the programmed controller, the machine can automatically perform steps to tend plants perfectly: Determination of the irrigation cycle by time, temperature control, insurance for adequate brightness, appropriate brightness change for the crops with cycle of light sensitivity, specially constructed nozzles can switch from drip irrigation to spray and vice versa, create humidity by misting water saving. It is suitable for using foliar fertilizer.

If the automatic plant care machine put into application, farmers can take advantages of water resources, bring nutrients to the plant, reasonable light, and shorten seasonal cycle. However, experts noted, besides the advantages it still exists a certain number of problems when put into use, in which it requires farmers to work the land carefully, and ensure to cultivate the proper seasonality.
