When we went on our vacation to the family farm I was worried about all the plants in the garden and the indoor plants. We were leaving for 5 days and since we are new to the neighborhood, we didn't want to ask the neighbors to water our garden. I've always seen those commercials of the Aqua Globe that you stick in the containers to water the plants, but being as frugal as I am, I'm not into buying a $10 globe. My neighbor across the street said they use soda bottles, so I started collecting bottles like crazy. LOL.
