One of the problems in hydroponics is that when the water temperature is crossing the 26 degrees Celsius (80 F) the oxygen level in the water dropping and it is affecting dramatically on the plants. Below you can 5 tips that will help you keep the water temperature under 26 Celsius (80 F) and give your plants good chance to survive very hot days.
Shading
the shading should be at the level of 30% to 50%.
Ventilation
by using a fan allows plants to evaporate through the stomata and decrease the overall temperature Will allow plants to perform evaporation through their stoma and thereby cool themselves.
Oxygen
The higher the water temperature, the less oxygen there is in the water. Simply add air pump with air stone to the water container. The pump power and number of air stones depend on the container size.
Use white containers / pipes
always use white containers for hydroponics because from all color’s white warms up the least.
Use of frozen bottles
add frozen bottles to the water container during the hot hours. It’s important that the frozen bottles will be closed so that the water that thaws from the ice will not mix with the water in the container and change the pH level and the fertilizer / water ratio.
