Is that just a normal tote or is it a food safe tote. You don't want to be responsible for killing people
It's a very debatable subject, commercial growers are not using special plastics, it doesn't appear to be a threat. You are not consuming food stored or drinking the water from these containers, you're consuming a plant that seems to be able to work out toxins. If I put chocolate in the tote doesn't mean I'm going to have chocolate flavored lettuce... Plants rework elements in the water.
Keep in mind this is a sale thread
