You could construct a wood frame or something similar and put shade cloth over the top if you wanted to. I've heard others say they sat a lawn chair over their plants, but your plant could be too tall for that.
Glad to see you on here, too. I've been working so much outside that I've been unable to post as much. I have too many Desert Rose plants. I planted seeds and they are getting huge under the grow light. They really like those!
