My light meter is reading 4,000 - 5,000 at plant level
and 2000 - 3000 at shelve level....
On a 12 hour a day timer

I have a mix of orchids on that shelve:
Oncidiums, Vandas, Zygo's, and few young cross...

Is this too much light?

Some leaves of some were turn a little yellow, so those got
moved to the ends of the shelves.

Is there any good web sites that maintains a light of orchids and
how much light is right for them?

Thank you
Steve

Searching Culture Sheets and Articles by Charles and Margaret Baker
http://www.orchidculture.com/COD/FREE/index.html, you will find
light requirements for a good cross section of orchid genera. Once
you know the plants' light requirements, you can position them
accordingly.

-- Larry Dighera,

Hi Steve, I remember back when I first started growing, there was a list
that was put out by
the Orange County Branch Cymbidium Society of America.
It had most of the popular orchids & listed their required Foot Candles
of light.
Vandas........ 2500 to 4000
Cattleya...... 2000 to 3500
Oncidiums....2000 to 4000
These were for growing in a g/h.
I also remember my light metre having a switch for florescents?
I will try to find the list if you are interested. It had other pertinant
info like
Fert mixture, potting mix, best time to repot etc.
Cheers Wendy
