Advice sought on grow bags longevity VS trying to source leftover landscaper's pots

I realized that some information that I posted in a separate thread might benefit this conversation, so I am posting it here as well:

@Audi_o_phile

seeing those white HDPE buckets that you’ve got, I hope that you and everyone else is already aware that you can get them for free from most fast food restaurants that serve any sort of sandwich with a sliced pickle on it. They usually just get tossed into the garbage when empty, and store managers have been very accommodating with asking their employees to just set them beside the dumpster for me to pick up on a weekly basis.

A friend recently mentioned that his work office is right beside another business that does maintenance for household swimming pools, and that they generate a large quantity of waste HDPE buckets that they receive calcium hypochlorite in for the chlorination of pools.

The smaller size that they receive are roughly 6.75 gallons in volume, with a diameter commensurate with a 5 gallon bucket and a plastic flippy handle. The larger buckets are roughly 12 gallons in volume, much larger in diameter and height, and have either two or four handholds molded into the area below the rim.

I am not sure for how long they need to be aired out before they are safe to use for plant-type of purposes, but after a few days sitting open in the sunlight I detect no chlorine scent lingering.
