I'm in the first week of my grow. When I first planted the seed I made sure the soil was already watered. Now that they've all sprouted out of the soil I water them with a spray bottle keeping the top moist twice a day. I'm wondering should I start actually watering them till I see run off? How often should I water? I don't want to over water since they're so small but I've been told they look kind of dried out. But shouldn't the soil not always be wet? They're still in solo cups btw. Help!!
