I used Impact rated insulated glass on the bottom sides up to 5' high. Then 1/4" Tempered for the rest of the sides and the front and back. The roof is 2 layers of greenhouse poly that is inflated with a fan to provide more insulation. Ran electric and h2o out to it and did a misting watering system that hangs from the roof with drip lines all on separate valves. All the arches are made from conduit that I bent to form the arch for the plastic to lay on.
Its going great so far. Cannot wait to finish it up this summer. Got a nice couple month head start on seeds this year.
Oh, and I have 150+ gallons of water in large drums for thermal mass.
Sounds like what I want to eventually build, except that I'll have to use something that can handle snow load on the roof for mine. I'll probably end up going with a couple layers of that clear corrugated poly roofing they sell at Home Depot or something.
I have a grove with 19 Avocado trees (17 Haas and 2 Fuerte). 16 of them are mature and three are newly planted this year. I also have three orange trees (1 Naval, 1 Valencia and 1 newly planted Blood Orange tree), two tangerine trees, a lemon tree, a Fuji Apple tree (new), a new Lime tree and a new Doughnut Peach tree.
Last year we pulled off about 800 pounds of Avocados. Most of them were small (about 2"). We picked late the previous year so I don't think they had time to grow big. We also picked about 200 pounds of tangerines last October.
We also have a flower garden in the back. It doesn't need much attention. We have the irrigation on a timer for most of the flowers around the property and also for two of the orange trees and the lemon tree.
The Avocado grove and the other trees need to have the water turned on manually, usually once a week. They each have their own sprinkler head and the irrigation system is divided into three zones. I can only run one zone at a time due to the large amount of water required. We use about 50,000 gallons of water per month.
I've got a pair coffee trees and a pineapple, plus a pair of small lemon trees in the house that finally have fruit on them, so I'm pretty excited about that. I want to get oranges and grapefruit as well, but I just don't have the space for it right now.
