Subject: Re: watering plants while traveling
Another idea that I have read is to use candle wick brought from a hardware store. If you put one end of the wick in the soil and the other end in a bucket of water that is placed higher than the level of the plant, then the plant will drink the water from the bucket through the wick.

I haven't tried this though, so I don't know how it works. Sounds good though
