What are my options for eco-friendly and chemical-free/nontoxic planters?
I am trying to find the most eco-friendly, non-chemical-leaching planters to grow my vegetables/fruits/herbs in. I am very apprehensive about using plastic pots, due to chemical BPA leaching. I have just discovered coconut liner window planters as an eco option but noticed that there is some sticky binder substance. What is this, and are they 100% toxic, chemical free? What are your best recommendations?
Anything made from ceramics, glass, metal, or even cedar would be a good candidate, depending on the specific use.
- The BPA issue is related to #7 plastic, usually in the form of a clear epoxy-type lining that exists inside cans and some baby bottles, etc.
- Most plastic planters probably don't have BPA, but nonetheless, plastic does have the potential to leach even if it's not BPA.
- Certain plastics are safer than others (#1,#2,and #5 plastics are the safest, and #3 PVC and #7 are the worst).
With the exception of glass, it's fairly difficult to completely waterproof anything without incorporating a plastic-like polymer or a petroleum-based product.
That said, if you can find a creative way to eliminate the need for a complete water seal, that would probably be your best bet.
