Thanks for all the answers and so quickly ! Since you asked, I live in Arizona. Here in fall, there are lots of dust storms and rain. Also common flash floods. The other thing is I give the plants a certain amount of water, and rain interfering could be bad with the current conditions of my plant, since it might get the leaves wet. Although there is an overhead balcony that shields some of my backyard from rain, the plants wouldn't get much sunlight since the overhead blocks the sky. That's why I don't want to put them outside.
