It could be that keeping that cellular shade drawn and then lighting the plants with those gooseneck strips will solve the problem, but I can't really say as I don't know anything about artificial plant lights.
I will suggest again the possibility of a horizontal slat-type blind in that window. Wood or faux wood would look nice since that appears to be your living room or family room, and the window frames are wood. I find horizontal blinds to be very versatile. You can do anything from completely open, meaning slats drawn all the way to the top of the window frame, or completely closed, and everything in between.
Also, I don't know how big that room is, but is there a possibility you could use a larger table, one that sticks out a little more into the room, meaning some of the plants could be further from the window?
