| A lot of hobby growers do not take this serious enough… In-situ, orchids are exposed to a constant breeze or good air movement. Poor (or no) air circulation when we grow orchids inside promotes problems such as fungus and rot. Good air circulation is especially important since orchids like to grow in really humid conditions. The more humid it is, the better the air circulation has got to be. Good air movement can also help prevent cold/hot spots between the plants and produces a healthier plant over all – and this is a very good thing. | ||
My growing areas |

| I use 140mm computer fans on both sides of every shelf in my growing room. I have two 80mm fans going in the warm vivarium and four in the cool viv. plus the cool air intake. There is one 80mm fan blowing air into each of my mini green houses when I have the lids on them. Each fan is daisy chained to a 12V power supply, about 4-5 fans per unit. These power supplies are adjustable from 3,5–12 volt, so you can easily adjust the fan speed to control the air movement. The fans in the mini-green houses only run at 6 or 9V with only a small slot open for the intake. This way the fans circulate the air inside but do not dry out the interior too much – it is supposed to simulate a humid rainforest not a dryer… |
