The "Tokyo Micro Garden" is a tiny, living plant in a gel-loaded sealed jar that you hang from your cell-phone strap. This is just great, but god help you if you try to take it onto a plane. Thanks, TSA, for making life suck a little more.
These plants have everything they need within the nutrient-rich gel they grow in!
It's best not to leave them in direct sunlight. The exposure from your daily activities and room lighting will do just fine.
With minimal phone-drops your Tokyo micro garden can last you 6-8 months!
