I'm designing a vegetable/fruit farm for a upcoming eco-lodge in the mountains of southern California: 4,400' elevation, zone 8b, an ample supply of water, and good soil. The main challenge is daily temperature variation. During the summer, it can be in the mid 30s at night before rising to the 80s during the day. My question to all of you is, what strategies (other than greenhouses/hoophouses) are you aware of to keep the ambient temperature more stable on an acre of land? My instinct is to use perennials (tree + shrubs) around the perimeter to block wind and hold moisture. I'm also interested in ponds as heat sinks but don't know much about the subject, so any help would be great!
Use large masses right next to or in your garden (like boulders and ponds) to absorb heat during the day and slowly release it at night. Try to get them in the sun as much as possible. Sepp Holzer does a lot of mountain farming. I would suggest looking into his methods
