Hydroponic gardening has a lot of advantages in growing your favorite plants. Whatever season or weather, hydroponic gardening can make your seasonal plant to grow perfectly. However, there are several different specific types of equipment that are needed for hydroponic gardening. Choose the best water pump is one of the things to consider in using hydroponic method of gardening.
The hydroponic pump size matters in deciding for hydroponic gardening because it will depend on how big of a size your garden will be. With that said, you need to determine the volume and the height of your hydroponics. The volume can be calculated by how much water do you want to put in your hydroponic system. Even if you are going to use many growing chambers, you can calculate the volume by multiplying the water volume to the number of growing chamber you are going to use.
The head height of the growing chamber is as important as the volume of the water needed in the hydroponic system. The head height is the altitude between the pump and the system. If the head height required is different from head height designed then the delivered water will be insufficient. There are also variables such as head loss that needs to be considered in the desired height of the hydroponic system.
There are several manufacturers that offers a wide range of pump sizes for different gallons per hour requirements. Usually on some pumps, the maximum head height determines the level of water with the highest pump pressure. For example, the head height is 6.89 feet(the given highest altitude) above the ground, the pressure will be zero as it doesn’t need to lift any water.
Types of pumps that can be used for different sizes of hydroponic systems
#1 Submersible pumps
The recommended type of pump for small hydroponic systems are the submersible pumps. It is less expensive and easy to use. This type of pump doesn’t also require pump fittings and leaks are unusual. Submersible pumps are also the hottest pumps in the market nowadays for small growers.
#2 Inline pump
For larger hydroponic systems, the recommended pump is the inline water pump. It is more powerful than the submersible pump. This type of pump is also recommended for places that are to hot or if the plants’ roots are always submerged in water.
(There are some feedbacks from other growers that a simple hydroponic for window farm can consist of an aquarium pump for hydroponics. This type of system worked and was able to pump water with high window heights.)
Some of the best hydroponic pumps that are available in the market
This pump has a recommended capacity of 40 gallons. The maximum pump pressure of this model is 400 gallons per hour at 0 feet and 100 gallons per hour at 6 feet. This pump has an adjustable flow and can be used both in freshwater and saltwater. This was well introduced in the market to many hydroponic growers but it can also be used in aquaponics and aquariums.
This water pump has a recommended capacity of 40 gallons. The maximum head height of this pump is at 6.5 feet. However this system doesn’t offer an adjustable flow. This is labeled as a powerful oil-free pump that works well with both hydroponics for fountains and ponds.
