I stumbled across a great planter idea - styrofoam. I've got a cooler, and some portable bait containers now that are a great size to turn into a planter. The only thing is ... I'm not sure how to paint them. I know it's possible, but there might be a specific paint to use. I bought a can of spray paint which actually is melting the styrofoam. No help there. Any paint ideas?
Also - I am needing to put tomatoes in containers and am wondering about using these for the containers. I know edible fruit plants you want to be more careful about what they're potted in. Is styrofoam safe? Is painted styrofoam safe? I try to eat organic produce, so it is important to me that I'm not inadvertently eating chemicals. Thanks guys!
