Atmospheric Controller (SPECIAL ORDER)
Atmospheric Controller (SPECIAL ORDER) at HorticultureSource.com -
Solatel Atmospheric Controller (SOLTHP-100) (SPECIAL ORDER) The Solatel THP-100 coordinates ventilation and CO 2 (carbon dioxide). This is required when temperature and humidity are controlled by a vent or exhaust fan. Hot or humid air is blown out of the growing area and fresh air is then drawn in. This continues until both temperature and humidity fall below the dial settings. CO 2 is only dispensed during the day when plants have light for photosynthesis. It is not dispensed when the fan is operating, which would waste CO 2 . When connecting CO 2 equipment, a repeat cycle timer or CO 2 concentration controller (not included) is plugged into the THP-100. The CO 2 tank valve or CO 2 generator then plugs into the timer or controller.
