Product review (3 stars): Temperature an humidy instrument
I have some orchids in home and since I live in the midwest, it is very difficult to keep them growing successfully, especially in the winter time.  Orchids typically require a lot of humidity.  The only time that I was successful brings them back to bloom is when I grew them inside the yoga studio.  I always suspected that the sweat from the yoga practitioners made them get enough humidity to stay healthy.

I cannot say that this instrument is very accurate, but during winter season, I store my house orchids in a special glass container and I monitor their environment carefully.  So far plants look healthy and I am hoping that they bloom again next time around.
