Rainwater is a great resource for outdoor cultivation as it provides many benefits. Rainwater has low levels of salts and minerals which makes it ideal for irrigation purposes. The pH level of rainwater is neutral which reduces the chances of plants developing nutrient deficiencies due to incorrect soil pH. Using rainwater can reduce water bills significantly since it eliminates the need to purchase water from a supplier. Collecting and utilizing rainfall helps to conserve resources by reducing reliance on municipal sources.
