I personally wouldn't do it. I don't see any benefit from it, other than maybe looks. But I would be worried of some fungus or mold growing underneath. In my last grow, I actually had some fungus. But I could spot it fairly quickly.
That being said, we are all not professional gardeners, but learning from experience. Do what you feel comfortable with. And if you grow a wicked weed, share some!
