You are not missing a life, this IS where it's at...
Your present set up looks very neat and there is plenty room for expansion. Nice job on the deck! I can see the Snap and Grow as a protector at times, keeping it cool in Summer will be a major challenge.
I totally clean out my greenhouse every Spring, starting now with my Cacti. I keep everything outside over the Summer. We were threatened several times through the years with hailstorms, but my area was always lucky and it missed us. I have 4 large pieces of window screen material ( cheaply to be had at Home Depot) handy/ready to throw over my Summer growing area ( a large cage) if a storm like that threatens. Sooner or later it will hit us too one of these days....
