so happy I found a Craigslist post for these. They say they are BPA free and #2 recycle food grade. $15. I figure I can cut them in half and get two large planters out of each. Just can't find healthy food grade planting pots anywhere so this seems like a great answer. If I knew someone who owns a restaurant I could probably get plenty recycled. This is the next best thing I think. They are blue barrels which the web says are industry standard for transporting food products. Can be painted on outside with spray paint suitable for plastic or screen them with lattice to make more decorative. If cut horizontally can then be put on wooden frame and use as raised planter. Or cut the other direction to make two deep planters for larger plants.
