Hey friends -- just thought I'd share..

In 2015 I started a greenhouse project and finally completed it. It's an 11'x14.5' on-house/lean-to greenhouse constructed with upcycled windows. Its purpose was to capture a Mediterranean climate in Colorado, zone 5, with minimal intervention to grow figs, citrus, pomegranates, cold-season vegetables all winter, etc. It actually came out better than I would have expected, and its still an ongoing project (next is a gutter/rain collection system). It utilizes a Subterranean Heating and Cooling System, roughly installed.

I took a few videos of it. They can be a little long-winded and sloppy at times but nonetheless, I figure that some of you may take interest so I hope you enjoy.

Here is the overall:

nice job good luck with your new green house!

Thanks Dave!

Totally cool!  Now you need to make it 90 x 60!   :)

Haha, that's what I was thinking.  Would love to do a huge and improved version in my yard. 

Very nice job!  Good luck with it!

Hey, that is an beautiful greenhouse! I really enjoyed knowing how you put the various windows together and how you even found that one in the dumpster! And you are right about that heating technique has been used for quite a ling time! Great job!!! I also enjoyed the tour of your currently growing plants. My favorite are the figs :-)

Thanks for sharing your video. Excellent!

Beautiful greenhouse and plants! I especially like old windows used in projects like this, and you placed them in a visually pleasing way. Very nice and inspiring..

Thanks! 
Yea, I figured that it would come out a bit visibly awkward, but it was minimized quite a bit by planning out the best possible placements. While it still exhibits a bit of interesting "character", the result is not as bad as I thought it would be.  : )

Yes, very pleasing!!!

Lots of brebas already underway in here! First winter season was a success with minimal intervention via an oil-filled space heater for several of the absolute coldest days, and this was just to keep things like bougainvillea and aloe alive. Otherwise the figs, olive, pineapple guava, future pomegranates, and most citrus would have been totally fine with no intervention. 

The subterranean heating ran off of a very low powered duct fan thermostatically controlled that didn't seem to make any dent in our electric bill.

We'll see how summer does, especially in regards to heat and ventilation.

I remember when you posted this...good to know it worked well. Please post pictures when you can.

Very nice greenhouse. Keep us posted please

Thanks.  Sure will.
