4 Methods to Keep Your Hydroponic System’s Water Cool

Hydroponics is one of the many different methods for growing plants. Its biggest advantage is that it uses water more efficiently, increasing output three times more than traditional methods with the same space. Unfortunately, hydroponics is not the easiest method to grow plants in, and many factors need to be managed to grow plants successfully.

One of the factors that you will need to pay close attention to when using a hydroponic system is the temperature of the water. Water that is too warm can harbour bacteria and does not hold oxygen for too long. With that in mind, if you are wondering what you can do to keep your hydroponic reservoir cool, here are some tips you can try out:

1. Insulate it

Prolonged exposure to light can heat objects, especially those that are painted dark. If you have light fixtures just above your dark tanks, they might be warming the water too much. To solve this problem, you can repaint the top a lighter colour or insulate it with a reflective material. The second option will reflect light away from the surface, minimizing its heating effect.

2. Use a cooling coil

While cooling coils are used in many different ways, they all serve the same purpose: to cool something. In this case, the cooling coils cool your hydroponic tank’s water. To make your cooling coil, you can purchase a metal tube (preferably, copper or stainless steel) and form it into shape. This will then sit inside your tank with a hose attached on both sides. On one side, water will enter, while on the other side, water will drain. Note that while this is highly effective at cooling the tank, it uses up a lot of water.

3. Bury it underground

If you have an external hydroponic garden, this is a method you can consider. Since underground temperatures are generally much cooler than on the surface, burying your tank in the ground means that water will stay cooler far better. The only problem is that if you need to drain the tank, pulling it out can be quite a challenge.

4. Place it under the shade

If you do not want to bury your tank, you can place it under the shade. This is also possible with an indoor hydroponic system, where you can protect the tank with a cover. This prevents light from reaching the tank, keeping it cool and algae-free.

Conclusion

By applying these tips, you can make sure your hydroponic system enjoys cool water at all times, facilitating your plants’ growth with oxygen-rich and algae-free water.

With that said, there are various other ways you can keep your water cool. For instance, you can use swamp coolers or water chillers to keep temperatures down. Whatever you decide to use, these solutions are vital to our hydroponic system. However, these solutions will come at some cost. You need to compare these different methods and pick that one that makes the most sense for your budget and needs.
