Not all plants will respond well to indoor hydroponics, but there are still plenty of good options. Herbs (mint, oregano, basil, rosemary, lavender, and sage) grow fast in water and will even start to produce a new leaf every day. Some houseplants that also work well are English ivy, philodendron, wandering Jew, purple passion, and coleus. Finally, if you’re looking to add more flowers into your home, root some begonias or impatiens in water. They’ll even bloom during the winter!
