I have a few. Some are from laundry detergent I used to get from Sams Club, and a few from some construction workers that were using them to move dirt (Old paint containers.) Now we have liquid detergent with a smaller easy despense nozzel. I'd really like to get a few more for my plants. These things are the best grow containers I've found and they'll take my plants through a whole grow cycle with no root problems. It's not important enough for me to go out and actually purchase them from a manufacturer; or even buy multiple gallons of paint/detergent just to empty out and grow a plant in. It is important enough to find other sources of these miracle grow containers (Pun not originally intended.) So, if anyone knows of anywhere to get five gallon containers besides detergent and paint; I'm all ears. I already checked the construction sites around here.
