I hear my name again!
Rick Corey, that is good information.
I keep a fishtank over the Winter in the greenhouse, twice a week many of my plants get watered with Aquarium water and my Adenium seedlings ( seeds from the same plants as Ken's, but started in April 2015) get a bit of that too once in a while.
I see that talk of my greenhouse is coming up, I do have the Geneva greenhouse built by Florian and it has a glass ceiling and it is part of the house. Yes, you can make it to be an extra room to sit in. That idea went out the window during the first year, I just choose to fill it with mostly Orchids up to the gills. Nothing wrong with giving our favorite growing space a name to refer it by.
