The following focuses on plant habitats, and in particular how they affect orchid culture in this country. One facet of natural habitats for most of the orchids grown in this country is significantly different from the conditions naturally experienced here, and this will be highlighted, together with other significant aspects.

HABITAT 1 
TROPICAL LOWLAND RAINFOREST HABITAT

One interesting statistic shown in the next graph is the general cloudiness normally experienced within this habitat, with only 8 clear days on the sunniest month, and some months only having a single clear day. And this is not just this particular location, but is a general observation throughout this habitat. While conditions are relatively bright, full sun all day is not a regular occurrence. This is not to suggest that we should keep our plants shaded, as generally the best flowering will be gained with bright conditions, but with our high light intensities, especially during the middle of the day and during our summers, caution must be exercised. The provision of shade during the middle of the day, and increased air movement through the use of fans, and the maintenance of higher humidity by overhead spraying of foliage or automatic under bench misting sprays is an  appropriate response.  Generally plants will respond with increased flowering with bright conditions, the brightness, however, relative to the level of the light normally experienced in  its natural environment.
