A few plastic bottles, grow vegetable wall, eat while grow, do not occupy space

When it comes to planting vegetables, many people will dislike taking up space and do not want to plant them. But what about the reality? As long as we transform the disused plastic bottles at home, we can toss out a vegetable wall and pick it when we want to eat it. It's absolutely natural and pollution-free! Mom doesn't worry about my dishes not being washed clean any more!
