I knew my office manager had some kind of widget she was using to grow basil in a plastic bottle, but I didn't really think too much about it until I saw she'd picked up strawberries in the same style... so, having the product name, I looked it up. This picture came from Instagram; it's better than the one I took, so here you go. These are sold at 7/11 in Japan.
It's a freaking hydro-widget. I love it!
Her basil sits in a window of our office on the 8th floor; it gets a whole lot of light and does very well. We use it on pizza. So I'm thinking of picking one or two of these up (around $5, or $2.50 if I can find them on sale), tossing the seeds, and using them for peppers with a mild nutrient mix.
