By no means am I a pro at this as I am about a month into it. But when our Jackson isn't basking he loops through all of our plants constantly. I am getting the hint that more is better. So we have a big fiscus, hibiscus, two umbrella's, and three pothos. I hope the pro's come along soon because we are planning on a couple more plants and if there is such a thing as too much we are probably way past that point.
