Ray, Pat and Wendy,

Thanks for your input related to my questions. All good things to
consider!
I never really thought about the venting issues that my proposed
configuration presents (putting the gh on a 2' base wall.). I may
have to re-think how I do that.

I had checked out the littlegreenhouse.com web site and yes! they are
fantastic!

I'll keep you posted on my progress!

Lori
