Nadia tried to recall, "Air is the space in which everything happens. Might it be because it's asked to leave the marigolds 9 to 10 inches apart, so that their branches may have room to spread? In which sense, they act contrary to the fire plant Evening Primrose," she said, raising her hand.

"So air isn't only for their feeding but means space where the Marigold is," and to Greek in those times air was synonym of emptiness, wasn't it? "Might there also be a reaction to sound the Marigolds experimentate, since sound is the chief characteristic of Air? I have heard some flowers react to outside noises."
