It has been up for a couple years. Some of those big leathers are only about a year to a year and a half old. They grow pretty fast for me. I actually have been considering selling them because of the space they are starting to take up.
I just try to piece them in so everybody has some space. As far as lighting goes I just have a JBJ 4 X 65watt PC set up. It provides enough light for any softies or LPS.
