I'm not an expert so I can only give my 3 weeks worth of experience.
I've been misting the soil with the
seeds and the sprouts daily, and they've grown twice as fast. With my pole beans, they were supposed to sprout in 5-10 days and I got them in 3. By the 5-10 day mark, the sprouts were 5-10 inches long already. Haha. I've been misting my mom's cacti and ferns and they have kept a beautiful color and body. I went a while not misting the daisies, but they started to lose their color. When I misted them, they turned out like the fern. So I give a thumbs up to misting. As dodge says, they love humidity. =)
