| 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 Fractal computer fans on both sides of every shelf in my growing room and I have three 80mm fans of the same brand going in the warm vivarium. There is one of these 80mm fan blowing air into each of my mini green houses when I have the lids on them. The Fractal fans were not strong enough for the cool vivarium however – measuring 160 cm tall… so here I intalled 3 Scythe Gentle Typhoon, 120 mm, 1850 rpm fans instead – and they are amazing!! (0.083 A, 28 dBA, 98 m³/h).
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 while I run all the other ones at full power 12V. |
