15 Best Hydroponic Houseplants and How to Grow Them

You may be reading a lot about hydroponic gardening in magazines and social media. It’s an efficient and environmentally friendly way of growing produce. But did you know that you can grow houseplants too? 

Hydroponic gardening uses several systems to provide consistent water and nutrients to your plants without soil. Some systems use wicks to absorb the water into the plant’s growing medium. Other systems, such as Deep Water Culture (DWC), suspend your plant’s roots in a reservoir of nutrient-rich water.
