Week 2 - Bean plants

Remember those bean plants from last week?
This is what they look like this week- 

 I am a bit disappointed though. The lettuce seeds haven't come up yet and the rocket and tomato seedlings don't seem to be doing anything.
Maybe the lettuce seedlings need more water.

Before I left on leave for a week, I filled that green bottle right to the top with water. That water level has hardly dropped.
