Fan & Air Circulation
Hi, first post.
I've been a longtime orchid fan and grown many, but due to moving and various indoor climates and conditions, been forced to give away or lose them.
Now things are different. I've acquired a 40Gal tank and have programmed an Arduino to control humidity, light and air circulation.
What I can't seem to find reliable information on is how often I should be exchanging/circulating the air... Any thoughts on this?
Thanks in advance.
