We used Wall-O-Waters with great success for several years. We planted our seeds indoors on February 15, and transplanted on April 15th, removing the Wall-O-Waters after our average last frost date of May 15th. This gave us an extra month on the growing season. This year we have a greenhouse! We started seeds on 12/31 and have little chiles and tomatoes galore. Should be eating fresh ripe tomatoes in May. If you have a short growing season and want to get ahead of your neighbors, I highly recommend the Wall-O-Waters. Fill them with water while they are sitting around an upside-down 5 gallon plastic bucket.
