Different place, different problem. Here what we call a green house, simply a protected housing from the environtment
Rain being my most problem. Huge rain, would destroy many plants, including dropping branches the rain brought.
And then when it sunny, tropical sun would fry the leaves
Next you will have lots critters, grass hopper, caterpillar, bug, monkeys, squirells and all which will be happy devouring plants
or mosquitoes will munch on you.
Having a protected site with roofing and walls willbe beneficial.
Some plants can even be grown here, such rudbeckia, foxgloves, echinaceas, all are prone to rain.
