zone 9 greenhouse idea

So I am in zone 9a northern California. I almost grow tropical stuff. I want to create a greenhouse on my side patio right outside my door with an outdoor soaking tub to water it all in it would be about somewhere between 10 and 16ft wide I believe it is 16 ft though. three sides with one being the wall being my house. I would love to grow vanilla vine orchard for sure.  Maybe a pot of sugar can I believe it would top out at 9f depending on how I shape the greenhouse and what materials I can scavage. That being said before I take years gathering up materials I was wondering what could I do that is mostly off-grid to keep it from getting too hot or yet hot enough in the winter. what plants would but in it dwarf potted trees I am guessing I could have no more than two for the plans I have as it would be a multipurpose location as I said I am building an outdoor tub but it will double as a table surface when not in use. it is less than I believe the space is 16 x 25 ft I lost all my zone notes so I will have to remeasure but it is not too far from these I just need plant ideas preferably a container garden and a dual-purpose water feature if I need humanity up?

Heating
Just protecting the plants from wind will add a zone to it
Running your grey water into the greenhouse will keep it warm in the winter.
Lastly a 16ft X 25ft collection area will keep it hot enough during the day,
So really you don't have to worry about heating,

Cooling
Keeping the greenhouse cool becomes an issue. You want some bi-metal vents that will auto open once the greenhouse get hot and then close once it gets cool.

I live in N. California. I'm building a greenhouse, thought more for fun, and not as serious as you.  I've been reading about ways to heat a greenhouse without power. You can paint things like milk jugs and laundry detergent containers. Fill them with water. They retain the heat during the day, and help keep it from freezing at night. Also there's a terracotta pot heater that looks interesting. You get a large terracotta saucer in the center you put a large crisco with 3 wicks. Cover with a large terracotta pot, cover that with the next size, and the next. This is supposed to last all night, and give off a decent amount of heat.
I've had a small plastic greenhouse, and the main problem is keeping it from overheating. It gets so hot so fast.  I've been looking into solar fans. They are quite expensive.  I've been told solar fans for chicken coops are more affordable, though I haven't had time to check it out yet.  I also read on a past post someone mentioned getting a fan from a pick and pull or junck yard and connecting that to a solar panel.  I also plan to have a way to have a way to open up windows by the roof to let the heat out. Good luck. I hope you post updates and pictures.
