This totally looks do-able. We are trying to get in touch with UBeauty to see about producing these pots in the US as they are rather amazing. We will keep you in the loop repurposers!
UBeauty in Australia makes these plant pots from rubber tires. “Built to last, each pot is extremely durable, lightweight, frost resistant and can be placed indoors or out.”
