My wife and I got an orchid, our first !

Our two possible placements are in the same vaulted room with bright windows on the south wall. The attached JPG shows the locations.

Using my iPhone, the lumen readings are 2,000 to 2,100 on the table by the window. The other possible table is 21 feet away, across the room from the windows. The lumen reading there is about 550.

Recommendations on placement ?

Thanks,
Clark
