dhoffroad, I thought I might lend a suggestion. Although I don't have SPS, I'm well aware that the more possible light (regarding shadows vs. lit areas) available for SPS the better. So I just wanted to say next time you add any SPS frags I would lay it on its side that way the frag is actually receiving more light than if you stand it upright. Also if you were to cut the frag sagittally, and lay the two frags on their cut sides you would obtain an optimum lighting situation. Plus the frags will hopefully grow more branches with the increased light. Just my 2 cents.
