Hydroponics is becoming a favourite among indoor gardeners. This is because it reduces waste and produces a higher yield of crops. Hydroponics uses less soil and less water than most other types of gardening. It has similar environmental benefits to organic gardening.
Using rainwater for your hydroponics system lessens the amount of waste produced. There’s no need for treated water, which is chemically processed and filtered before it enters homes.
Rainwater is untreated, but it’s important to maintain the quality of the water as it can upset the balance of nutrients in a hydroponics system.
Choose a rainwater tank that is made of a food-grade material to ensure your water stays fresh. Pure rainwater is actually better for hydroponics systems as it does not have any chemicals. The chemicals used for treating water destroy beneficial bacteria that support healthy plant growth.
Growing Hydroponic Gardens
Hydroponics used to be a costly farming style limited only to high yield crops such as tomatoes. Instead of using soil, which houses disease-causing bacteria, farmers instead use an artificial, nutrient rich solution.
The solution is retained using some form of carrier, which includes artificial materials like mesh and gels. Some gardeners also used natural materials like coconut husks.
The carrier keeps the plant rooted, and serves as a water reservoir. Since there’s less runoff than loose soil, hydroponics uses less water than traditional farming and gardening methods.
Why Rainwater is a Good Choice
Rainwater is a good choice to reduce garden waste to zero. Since it is recycled natural water, there’s no energy wasted to treat it. When done on a large scale, it has the potential to reduce environmental strain.
Only specific types of plants thrive well in hydroponics systems. Plants with shallow roots, such as herbs and leafy greens, are best suited for this type of gardening. They also take well to rainwater.
Rainwater hydroponics is a great hobby. It helps the environment and promotes food stability in a community. If everyone starts growing his or her own plants, it can have a beneficial impact on the environment.
