In fact, plastic flower pots are mainly used for growing vegetables and flowers on urban balconies. The narrow sense of petty bourgeoisie life is the main factor. Many urban people have nothing to do after get off work, except for playing mobile phones and watching TV. There is no fun. Plastic flower pots are now introduced. It is completely possible to grow grass on the balcony on Sundays after get off work or on weekends, grow vegetables, water and fertilize. It is still very fun. I look at myself every day. The vegetables that I grow grow up a little bit. It feels very interesting and very happy, especially when I show off my small vegetables with my colleagues. The growth process is better and better than whose vegetables are grown. Lush is still very interesting, so planting a few pots of your favorite dishes on the balcony is very interesting, and it is also very in line with the petty bourgeoisie of current urban life.
