Watering tomatoe seeds

Question

This ia for a science project. Could you tell me why you should or should not water tomatoe seeds with water? Same with just milk and again with just coffee and why?

Answer 1

To germinate tomato seeds (get them to start growing), you need to give them moisture, as explained here:

Milk or coffee might work, but they might have different effects on the seeds than water does. Think about the pH (acidity) of milk or coffee and how that might affect seeds.
