Living with "Green" makes you feel relaxed and comfortable. Metaphys's planters are the replacement for flowers and plants that would normally need lots of attention. Keep it moist all the time by watering every day. Water the seeds sparingly until the first sprout appears in a week or two. It grows up to 40cm - 50cm in the temperature over 20 degrees (Celsius) or 68 degrees (Fahrenheit) which is the normal room temperature. All the Metaphys's planters come with orchard grass seeds and water retention agent. Once it grows, you can cut it so that the surface of the plants will be even.
