hatch, I apologize for being so long in getting back to your thread! It is a grand place to hang out. I'm going back through your thread in hopes the 2d time around will begin to form an understanding of your system. I truly appreciate the offer to walk me through a build based upon my attic pictures - I am seriously considering taking you up on your offer, as one day it will be too cold out by the pool to house any potted plants.

I hope all has been well with you, my friend! Be good out there!
