Plants absorb water and nutrients through the root zone and this part of the plant can face problems during extreme temperatures – be it summers or winters.
The best temperature for plants in a hydroponic system is 65-70o F. Plants will go into hibernation as temperatures fall below this, and their growth will slow down. They will come back to normal as temperatures start rising. You can use a thermometer to ensure the temperature remains in this optimal range.
Similarly, temperatures higher than this can mean plants will not be able to hold on to dissolved oxygen, which is essential for nutrient absorption. Apart from this, warmer nutrient solutions increase the risk of pest infestations. Exposure to higher temperatures also puts your plants under stress, which can stop plant growth entirely in extreme cases.
Installing a hydroponic water heater becomes necessary if the temperature in your reservoir falls below the ideal range. These devices work automatically once you submerge them in the nutrient solution. They will heat up the solution when the temperature drops and shut down automatically once it reaches the optimal degree. They come in different wattages and should be placed around the water flow to ensure proper heat circulation.
Hydroponic water chillers help in cooling down the nutrient solution if the temperature rises beyond optimal range. All you need to do is connect it to the water pump. It then sends in cold water into the reservoir. They come in different horsepower ranges, and it is essential to find the correct size for your hydroponic system.
