However, here are some other things people use:
* Rainwater: Many people collect rainwater to use on their plants, as it's often considered a better option than tap water.
* Filtered water: Some people use filtered water to remove impurities that can harm plants.
* Bottled water: While not ideal, bottled water can be used in a pinch.
* Nutrient solutions: These are often used for hydroponic gardening or when plants need specific nutrients.
* Compost tea: This is a liquid made from composting materials, which can provide nutrients to plants.
Ultimately, the best way to water your plants depends on the specific needs of the plant and the quality of your water source.
