I've just come across a duo of similar products that are fit for Good to Grow month, and just plain kewl. Leave it to the Japanese to find a way to be innovative with plants; Flowers in a Can ($10) are a bit like Red Bull, except when you pop the top, it gives you flowers!!!! Of course, you've got to toss in some sunshine and de l'eau, too, but you get the point. Dandee Designs Spring in a Can ($10) works much the same and grows grass, but I'm not sure whether the kit comes preassembled or not. Perhaps this is not the most cost-efficient way to grow plants, but I'm loving the packaging concept.
