So I planted a new Sunflower a few days ago, and instead of planting the dwarf variety I planed the Mammoth (12ft) Sunflower. Considering the dwarfs were smaller than I thought they’d be, maybe the Mammoth growing inside will be a reasonable height. And on that note, it’s growing MUCH faster than the others. Since sprouting, over the course of two or three days it’s grown to about 5 inches. I had the light 5 inches above the pot and the plant is just a few moments away from touching it, so I raised it a little for this picture.
