Hydroponic Water Temperature Control

A temperature controller can be used to set a specific temperature and monitor the actual temperature of the reservoir.

Hydroponic water temperature control. This temperature range provides an ideal setting for healthy roots and optimal nutrient absorption. It is a good idea to line the water reservoir and the hydroponic system with an insulating reflective material to protect the roots the water and the components from excessive exposure to direct sunlight and from fluctuations in the temperature. In easy terms ideal temps are between 18 and 20 ºc and if your water temps are anywhere near 25 30ºc then the oxygen levels can be as much as half of the desired levels in easy terms ideal temps are between 18 and 20 ºc and if your water temps are anywhere near 25 30ºc then the oxygen levels can be as much as half of the desired levels. Ideal hydroponics temperature.

Example lets say you have a 100 gallon hydroponic system. Sizing your hydroponic water chiller. Use immersion coils with a temperature controller. Butas a direct result of the water temperature being at higher temps the plants will need more oxygen at the roots so the problem is almost squared.

While nutrient temperature can fluctuate the main problem can stem from the grow room itself. Number of gallons in your hydroponic system x 8 33 specific weight of water at 68 f 20 c x temperature differential btu s required. Plants thrive better when they are in a constant environment. Locating the reservoir in a cool place helps minimize the transfer of heat from these sources keeping your hydroponic water temp at acceptable levels.

Experts agree that the best water temperature for hydroponics is between 65 f and 80 f. For ideal temperatures for good plant growth the surrounding environment should be around 70 to 80f. Even though roots grow better at the slightly higher temperatures of 70 75f 21 1 23 9c you would be inviting in pathogens and root diseases that thrive at these temperatures as well. Stay away from a deep water culture system because of the temperature fluctuations outdoors which cannot be controlled and may cause damage to the plants.

Experts agree that the ideal water temperature for hydroponics is the same as the nutrient solution temperature. You should give yourself a safety net and add 25 to this number.
