Is the approximate equivalent of Lowe’s or Home Depot and an important discovery. I bought two planter boxes to hang over my balcony railing and now that I know the design will work, I’ll buy a few more on my next journey. I think I want white flowers…they’ll look so light in the sunshine and luminous in the moonshine/streetlight. My herbs will all be at balcony floor level so it might look like a green carpet from the pedestrian viewpoint. I’ll send a picture if it all turns out!
