Winter has arrived and now it’s time to evaluate your indoor garden and improve the hydroponics systems and hydroponics equipments settings that suit the change in whether which is colder. In winters you’ll realize that the excess heat problem you face during summers is not the same during winters. During summers you spend enough on cooling equipment, fans and power supply to maintain an ideal temperature to get superior quality hydroponics plants.An ideal temperature for your room during winters is, between 70-75F without CO2 and between 77-84F with CO2, depending on the size of your room and the number of land per million CO2 the room air is. This is applicable during the lights-on cycle and during the lights-off cycle you can allow your room to calm down with temperature 66-70F with nutrients water temperature 68F. http://bit.ly/ehtOkO http://bit.ly/fCE7Hr
