Very nice looking. Given the numbers of plants, the next project should be a nice double-paned glass greenhouse. It will be cheap only $20K or so :-).

Did you toss a finish on that? Pine plus water will not age well. On projects like that spraying is much more time efficient. I would use a lacquer personally if the weather outside is appropriate. It requires lots of ventilation but dries fast. I use three coats on stuff that needs to be water resistant. Five coats for stuff like aquarium stands.

When I apply it, I open all the doors in the garage and put a fan on as well as wearing a respirator. Damn stuff is pungent but I love the results.
