With the popularization of green concept, urban vegetable planting is gradually rising. After the development of urban planting products in recent years, different development directions and strategies such as intelligent planting machines, planting cabinets and urban farms have been distinguished. Different from the traditional planting environment, the balcony glass room in the city is similar to a small greenhouse, and there are many factors to be considered for urban planting. Therefore, there are greater challenges for the design of planting products. For the multi factor product exploration, this paper will use AHP-TOPSIS method to establish the evaluation model of urban small-scale planting products, and sort the three main development directions of small-scale urban planting products according to the evaluation model, so as to provide some reference and suggestions for the development direction and design practice of urban small-scale planting products.
