Answer: I'm not sure why you are presprouting your sunflower seeds, they are usually planted directly in the soil, but wrapping them in a damp paper towel is the way to do it. Once they've sprouted, they should be planted. Seeds do not need sunshine in order to sprout (think about how seeds are normally buried in the soil). But, once they sprout, the roots need to be in a dark place and the stem needs to be in bright light. So, plant your sunflower seeds now.
