I see from the pictures that you are in a semi-arid climate like me.
I'm planning on making a greenhouse but more to control the humidity level than the temperature as I find that the leaves on a lot of my plants get burned and I think I can control that by adding moisture into the air inside a greenhouse.
Do you use an automatic misting system for yours and if so what brand/setup are you using?
Temperatures took a serious dip during the past week. This month as a whole has been very mild, but an unseasonable cold front moved in and just a few days ago, overnight temperatures went below freezing. Thankfully, the plants in the greenhouse made it through just fine. |  |
Outside temperatures yesterday were a high of 73 and low of 44, with inside temperatures at a high of 89 degrees and a low of 48. Although I am not completely satisfied with the low temperatures in the greenhouse, it is doing pretty well since I have not moved in the large thermal mass yet. So the project this month is to get the thermal mass moved in before cold sets in at the end of the month. |  |
The plants seem to be really loving the temperatures, the strawberries all of a sudden sent up a flush of flowers with sweet fruits to follow. Amazingly, they are just as sweet as the ones I picked during the summer. I am extremely pleased with this Eversweet variety and will definitely keep growing them. |  |
For an update on the mesquite trees I have been growing in the greenhouse, they are getting huge! I'm glad that the peak on the north wall is tall because otherwise these bad boys would be touching the ceiling! |  |

I use my misters in the summertime for solely for cooling, but a system could definitely be set up for humidity. For my system I use patio misters, but for your application, they have a tendency just to make everything wet. You most likely would need something with an extremely fine mist or a fog with a hygrometer control.

I live in Southern Cal. and will be moving to the mountains of Southern Colorado. Will I be able to grow my 50 or so potted cactus in a greenhouse? The winters are cold and snowy, although there is a lot of sun.

It really depends on the minimum temperature that your cactus can tolerate. Many varieties are native to high deserts so they can tolerate a good amount of cold. Check the plant database on the USDA website (http://plants.usda.gov/) to see how cold your cactus can get. I would allow your greenhouse to go through a season without any cold sensitive cactus inside. This will let you see if you need to make any adjustments to the temperature inside with either thermal mass or a heater.
