Rain is a very natural source of water. It is soft water when it hasn’t come in contact with foreign particles or materials. Soft water is the name given to water devoid of Magnesium and Calcium minerals and water directly from the rain is just this.
The softness of rainwater makes it ideal for laundry and washing dishes. This is because detergents and soap foam more in water that is soft. The soap or detergent readily dissolves and forms lather which makes the dirt and stains in the clothes remove easily. Washing the body is no exception as when rainwater is used to bathe, the body feels fresher and silkier. People with sensitive skin are encouraged to use soft water as it reduces the symptoms associated with hard water.
Rainwater is also used for a variety of household purposes, many of which involve cleaning. Drinking is where most people draw the line because although rainwater is considered quite safe for consumption based on its component, the method of collecting the water most times allows the water to come in contact with foreign particles which makes it not encouraged for drinking.
Many people have tanks for collecting and storing rainwater which they use in watering their plants or for other purposes. Since water gotten from rain is very natural and doesn’t expire, people do not hesitate to store up large quantities for future use.
However, sometimes rainwater stored up like this can develop a smelly odor. This is usually because of particles that get washed into the barrel while the rain pours. These particles decay and accumulate algae over time which then makes the water smell bad.
If you only intend to water your plants with the stored water, this shouldn’t be an issue as plants will definitely not mind the smell of the water. You only have to try not to spray the water directly on the leaves but on the soil instead.
