Hi guys!!! I am buying a light meter to help my orchids. My question is what time of day to measure the light.

I keep my orchids outside and of course, the amount of light changes throughout the day.
When should I measure the amount of light they get so that they don't get underlit or overlit?
Also, the highest capacity of the hydrofarm light meter I am thinking of buying is 5,000 footcandles. Is this high enough for outdoor daylight?
Thanks everyone!!!
