There was a comment to one of the posts showing Galvanized Stock Tanks for veggie gardens questioning if they were safe for planting. The reader read that there could be some chemicals from the Galvanization process that could leach into the soil, etc. The tanks we purchased (Tarter) are rated safe for cattle and are made in the USA, so knew they had to be tested and considered safe for planting use. I did email the company to see if they had any additional information. I received a prompt phone call back from Tarter explaining that yes their product was safe for veggie gardens and for animal use. They also called out that their tanks are used to gather maple syrup and they had no risk of contamination. I feel safe to continue recommending stock tanks for veggie gardens, but if you have a concern you can always plant in cedar containers.

I made a visit out to my client to check on there veggie garden and snapped a few photos to show the progress of the stock tank containers. The plants are growing wonderfully. 

We planted a veggie garden for a client this year using three 10 foot long galvanized stock tanks. These containers are placed on an irrigation drip line to help with the watering needs and are placed in a gravel bed for easy harvesting. Will make a trip out to get photos of the containers full planted.
