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?
