I do plan to keep SPS in the nano. I may utilize at least one of the 400w pendants over an SPS grow out tank. So now my question is this—should I start with the 250w and adjust the height of the pendant over the tank as needed? I would hate to start at 150w and then find out I actually need a 250w for the SPS then spit out more cash for the upgrade.

How many of you keep SPS in your nanos and what is your setup?
