Itâs a good sign that the leaves are still in rather good condition considering the root health. An orchid with minimal to no roots is worrisome, but we have lots of tricks we can try to get it to sprout new ones. In fact, my wife has been in this exact predicament with several of her rescue orchids. Root rot can happen so quickly sometimes. The good news is that you can still save an orchid with few to no roots!
If the temperature is higher that -20Â° vs. outside temp, look for areas where air may be getting in and heating the house. However, with the thermostat set to cool, the air coming out of the air escape should be between 45-60Â°F. Locate the vent. In some cases they may be on the floor, wall, or ceiling. For vents on the ceiling, the IR-IND allows you to gauge temperature (from a distance) as it leaves the vent.
It depends on the relative humidity and temperature of the ambient air. For example, under the temperature of 35 Â°C and the relative humidity of outside air 50%, the air in the premises will be cooled to 28.5 Â° C (drop of temperature for 6.5 Â°C). Under the temperature of outside air 45 Â°C and relative humidity of outside air 30%, the air in the premises will be cooled to 32.5 Â°C (drop of the temperature for 12.5 Â°C).
