Well I took a diferent approach in part because I had different priorities and a special set up.
Looks is very important to me. In part because I have a rental house and I need everything to look clean and uncluttered, so laying extra insulating on the outside was a non starter. I will Neely put up aluminet next summer on the outside but thankfully that is a lot prettier than plastic sheeting.
The bubble wrap I got is great and is durable enough that I could use it for many years I'm sure. And it's amazing how thick and sturdy it is. The change I the temp inside was noticeable the moment it went in.
I'm now having no problem keeping it 70 even 75 while it is below 40 at night.
I do agree on passive heating, though I am limited by space. I have a 75gal rain water tank gong into the corner this week, plumbed into a downspout just outside the greenhouse. It will have the extra benefit of being black and sitting in the corner getting sun on it. It should do a nice job as a heat exchange at night.
It's taking up a ton of valuable space but is doing so much for me that it's worth it. The orchids will be watered from it of course, but it's also plumbed into the fogger system so that works off a float switch.
I have some set ups that need nearly pure water ad it was this or a RO system and this was less waste and less maintenance. It also got running water out I the great house. The RO system would have to be a remote thing, yuck.
I'm putting in the shelving today and will take some more pictures when I get done.
