“To understand the true impact of indoor plants, researchers created a ten-question framework.

This framework examined technical performance, microbiology, health effects, social and economic factors, and the role of place. This approach helped experts look at indoor greening from many angles instead of focusing on only one benefit.

The team also compared 26 different indoor greening systems. These included simple potted houseplants, indoor living walls, and hydroponic towers.

Living walls cover vertical surfaces with plants. Hydroponic towers grow plants without soil by using nutrient-rich water.

This comparison gave building designers and managers practical guidance about what works best and where more research is still needed.” Earth.com
