Joe asked >I'm writing because I'm looking for a source (inexpensive is good) of >5-gallon containers (4-, 5-, or 7-gallon, ca. 20-24 liters). Most growers around here get theirs from Anderson Die & Manufacturing, 2425 SE Moores St., Portland, 503-654-5629. I don't know if they have a website, but they do ship nationally. The pots are UV stabilized and used widely for container growing in both greenhouses and open sites. They come in all sizes, even bigger than 5 gallon. Jane McGary Northwestern Oregon, USA
