I found a company who will send me some phosphorous acid flakes, but they said the smallest amount they will ship out is a 60 lb. drum. Now when I think of a drum- a 55 gal. drum comes to mind. Can anybee tell me how big of a container would be required to contain 60 lbs. of phosphorous acid flakes? I can't have a 55 gal. drum showing up at my shipping address, lol. I have searched only on the internet for this, I live in the midwest US, would this bee something I could possibly just stop and pick up at a local farmers co-op store, avoiding shipping all together? Thanks in advance for any insight offered.
