Being able to use tap water all depends on tap water quality. In some areas, tap water is high in minerals, chlorine, or other chemicals that can harm plants. If your tap water has a high concentration of minerals, it can lead to a buildup in the system, damaging the plants. Chlorine is also a concern, as it can kill off beneficial bacteria and fungi that are essential for the health of plants.
You can buy a water testing kit from your local garden center or hardware store. The test results will determine whether you need to treat the water prior to use it in your Tower Garden.
Should your tap water be high in minerals, you can use a water filter to remove them. Various types of water filters available, such as reverse osmosis filters, carbon filters, and sediment filters, can help remove impurities from tap water.
It’s important to note that using filtered water in your Tower Garden can help improve your plant’s overall health and growth. In addition to removing harmful chemicals and minerals, filtered water can help maintain a consistent pH level in the system, which is essential for plant growth.
Most people are able to use tap water, however, we advise Tower Garden owners to test their tap water in order to benchmark whether such water is suitable or not for growing crops on an aeroponic tower.
