I bought these little "Egg Plant" plants at Walgreens today, they come with soil and seeds already in this ceramic egg, and once they're mature they get transplanted. It's a bit hard to tell if they have enough water since the soil isn't dirt and is more pellet-like. Directions say to keep them "moist", I watered them until just a tiny bit of water stayed above the soil before sinking in. Is it okay if they end up with a little bit more water than needed, or is it better if they have slightly less than needed?
