Answer: Based on your description it is a little hard to tell, but generally seedlings need maximum light and good air circulation as soon as they germinate. If either is lacking, they may begin to either elongate and weaken as they stretch for light or they may be attacked by disease (misting will aggravate this). They will also grow best at moderate temperature, say mid-sixties or so. The best thing to do after the seeds germinate is to set them in a south window or under fluorescent light, and make sure they are not too crowded. Next, consider your watering. You need to water so the soil is moist like a wrung out sponge, not dry and not sopping wet. If the soil is too dry they will shrivel and fall over, if it is too wet they might also fall over. Hope you'll try growing squash again. Maybe sowing seeds directly outdoors will bring you better results. I hope so!
