How To Keep Your Hydroponic Nutrient Solution Cool In 6 Ways

How to Keep Your Hydroponic Nutrient Solution Cool in 6 Ways

How to Keep Your Hydroponic Nutrient Solution Cool in 6 Ways, You shouldn’t disregard the temperature of your hydroponic nutrient solution. An overheated hydroponic nutrient solution cannot contain the necessary oxygen for the plant’s root system.

High temperatures combined with an unhealthy root system create an environment that is conducive to disease and pathogens like root rot. You must have a strategy in place to cool the nutrient solution in your reservoir in order to withstand the heat.

The ideal temperature range for the hydroponic nutrient solution is between 65 and 75 degrees. So how can you keep your hydroponic nutrient reservoir cool?

Spend money on a reservoir chiller.

Investing in a water chiller is the simplest way to cool your hydroponic nutrient solution. The temperature of your solution is lowered by running the nutrient solution through a chilled coil in a typical water chiller.

With water chillers, you can set the temperature of your nutrient solution at a constant level more precisely than with DIY solutions. Because larger reservoirs require stronger chillers, reservoir chillers come in a variety of price ranges.

You might need to move your reservoir away from hot lights or other equipment if your hydroponic garden is indoors in order to keep the nutrient solution cool.

Fill your hydroponic reservoir with ice.

To beat the heat, simply add ice to your hydroponic nutrient solution. The ideal way to accomplish this is to fill a container with water, freeze it, and then add it to your reservoir.

Keep in mind that you don’t want to cool down or change the temperature of your nutrient solution too much. Depending on how hot the day is, you can use more or fewer water bottles, depending on the size of the system, and jugs for larger reservoirs.

Change the hue of your reservoir.

An effective way to reflect some heat away from your hydroponic solution is to change the color of a dark reservoir. Lowering the reservoir’s color to a lighter shade, such as white, will result in a slight drop in temperature. Wrapping your hydroponic reservoir in metallic material, such as foil or mylar, is an alternative to painting it.

Make sure your reservoir is full of cool water.

Adding cool water to your nutrient solution may be all you need to lower the temperature if the day is simply warmer than usual. Remember that topping off the reservoir dilutes the solution, meaning you might need to perform water changes more frequently.

your hydroponic reservoir underground

If you have an outdoor hydroponic garden, burying your hydroponic reservoir could solve your nutrient solution temperature problems.The ground keeps the reservoir naturally cool in addition to shielding it from direct sunlight.


It’s critical to maintain the coolness of your nutrient solution when hydroponically gardening. You should make plans in advance to beat the heat if, like me, you live somewhere with hot summers. To keep your hydroponic nutrient solution cool, combine the aforementioned techniques. Your plants will thank you with a fantastic fall harvest.
