Photosynthesis inhibited by high light levels

[beaniebeagle]

I've read in the past that certain algae and other plants have their photosynthesis shaped almost like a bell curve. So that high light levels, such as too much direct sunlight, actually will inhibit photosynthesis.

I was wondering if this occurs with orchids????

The reason I ask is that I acclimated all of my orchids to full sun last year to keep them in one group outside. The very frequent misting helped keep them from burning. A good number of my orchids don't require more than just bright light.

So I was wondering if I inhibited growth by doing the direct sun exposure, but they seemed to have grown just fine.

Yes, it can, but the levels of light that inhibit photosynthesis is dependent on the type of orchid in question.

Different orchids require different levels of light for proper levels of photosynthesis.
