I went through my fair share of trial and error in the beginning. I'm still trying to figure everything out. Everybody starts somewhere, and if I can help one person avoid breeding rats in fish tanks or hamster cages then I did something good LOL.
You're not the first person to ask about the watering system. They're not that tough. Its basically a very long, very bendy, water bottle. You have a bucket, a line that carries the water from the bucket, and a sipper where the water gets carried to. As long as you keep the bucket above the sippers there are usually no problems.
