Hmm. This one's a toss-up, up to you, the reader. There are three tobacco plants, one of which skyrocketed four feet or so in the last month. The one on the left is in sifted soil to remove dust. This allows for much better drainage and air movement, a larger concern when the plants are watered twice a day for 10 minutes. Less water-logging means happier plants.
My favorite is the cannabis-looking plant in the middle here, grown by a member. It is actually a type of hibiscus, Hibiscus Cannabinus. Here these two plants have grown to about four feet tall, in a 4-inch container.
Another interesting plant is this spectacular angel's trumpet in the background, with 6-inch flowers that smell most fragrant at night.
