The trouble with relying on the light is that you have to turn it off at night so your boy can rest. When you do, the water volume is too small to maintain the daytime temperature, so it drops back down to room temperature. Both the cold and the sudden fluctuation aren't good. Also, because it isn't adjustable, it could end up giving out too much heat.
Although bettas do like plants and do come from heavily planted areas, nosediving in it all day is a bit odd. Maybe a second plant would give him some more confidence? :) Or a Zoomed betta log, I've heard good things about them. :)
