@diygarden.lab: I Mixed Phosphorescent Powder with Varnish to Make This Glowing Planter I built a custom mold for the concrete out of old LEGO bricks, poured the cement, and coated the finished planter with a mix of phosphorescent powder and varnish. Now it glows in the dark like something futuristic. What do you think of this setup? #DIY #homeimprovement #concreteplanter #handmade #interiordesign
