Phalaenopsis - Right light for your Moth OrchidOrchids can be classified into 3 groups depending on their requirement
of light. The high (3,000 foot candles, medium (2,000 foot candles)
and low (1,000-1,500 foot candles). Generally most orchids require
plenty of light, preferably 6 hours per day. Orchids are tough and
can handle more or less of their recommended light.
Gauging Your Light by Showing the GreenLeaf color is one of the best ways to determine if your plant is getting enough light. Houseplants may look best with dark green lush leaves but that’s not generally true for orchids. Leaves that are dark green are attractive but are a sure sign of not enough light. A plant that is grassy green in color means the plant is receiving enough light to bloom. Forgetting all the foot-candle measurements, below is a simple way to figure out if you have enough light. Place your hand six inches above the leaves and look at the shadows cast.
For natural light your best bet will be a southern or eastern facing window. The afternoon temperature can be too hot in a western window and the northern window is usually too dark. Too much sun can bleach out the leaves and cause sunburn, eventually turning black. It may be necessary to move plants around as the season changes or to regulate the amount of light. A sheer curtain can also provide for some light shade. Artificial light is excellent. You can provide sufficient light with 4 fluorescent tubes in one fixture placed 6"-12" over the leaves, for 12 to 16 hours per day. Remember: Orchids that are growing and do not flower often require more light. Potting or repotting of your phalaenopsis is usually done in the spring. Related Topics |
