    Question Grow area created wind chill?

    I have my orchids in a portable greenhouse indoors with some fans to increase air circulation, especially since the humidity is quite high inside of it (around 80-90%). I've set two max/min temperature and humidity gages inside - one at the top and one at the bottom to keep track of the grow area environment.

    I was just wondering about the increased air flow + humidity and their impact on wind chill because inside the grow area feels a lot cooler at times then my temp monitors say. Has anyone any knowledge of this in their grow areas? I don't want to have my orchids too cold by increased wind chill at night and risk plant damage, but I know that humidity is important and with more humidity there needs to be more air flow so you don't have fungal growth taking over everything. Any input??

    Animals loose heat from their skin from wind chill, being plants don't produce heat it is not an issue.

    Any warm object will cool off until it reaches the same temperature as the surrounding air, unless some energy input is keeping it warm. Wind chill speeds up that cooling process but does not make it colder than it would have been without wind. The fans might feel cool to your skin because you are warmer than the air, but it does not affect the temperature of the air or plants in your enclosure.
