It was brought to my attention the need for "food grade containers", which led me to a lot of research, and here is what I found.
First off, I took a black 5 gallon bucket designed to grow in from a grow shop and checked the bottom of the bucket. It was stamped with a #2.

I then looked at the Lowes bucket.

I noticed the same markings, which led to some research. Here is what I learned. Our number 2 markings prove these buckets are High Density Polyethylene, or HDPE, which is the most commonly used food grade plastic. Look for a number 2 inside of the symbol to confirm that the bucket is HDPE.
Our reservoirs are marked with a #5, and according to research it too is food quality safe.
Now, unless I'm missing something here, I'm putting this one to bed.
