Hi - I am looking for something portable to water my beds and flowers with. I have seen something in greenhouses with wheels that they use to water but I have no idea where to look for something like this. I've "Googled" every combination I can think of but nothing meets what I am looking for. It can't be too big or it will be much too heavy to pull around the yard. If anyone has any suggestions I would be most appreciative, please include web site if you have it. Thanks!
