With the Metro-Grower™, you can grow your own endless supply of organic vegetables and fruit trees, whether you have a backyard or not. It can be used anywhere, anytime – a patio, balcony, fire escape, backyard, or greenhouse. The Metro-Grower™ utilizes a unique sub-irrigation watering system to grow abundant, healthy plants. 
The unique sub-irrigation watering design waters plants the way nature intended - from the bottom up. Watering into the reservoir allows you to visibly monitor the water much more effectively than in other self-watering containers, in which you must water through a tube into a hidden reservoir. The soil system wicks moisture up to the roots, drawing nutrients up with it.  The soil system also air prunes plants to keep the root growth constant and prevent root circling. With the constant exposure to oxygen you no longer need to worry about over-watering either.  The fresh air prunes the tip of the roots which causes them to branch off, creating an even healthier root system.
 
At a Glance
With the Metro-Grower™, you can grow almost anything, anywhere: apple trees, cherry trees, blueberries, potatoes, tomatoes, peppers, beans, corn, lettuce, squash, cabbage, onions, strawberries, ornamental plants and much more.  
The sub-irrigation watering container has 3 pieces: saucer, pot, and soil separator, made from a blend of recycled and virgin plastic here in the USA. Water into the saucer at the bottom and the soil and roots wick the water up through the soil separator to feed the plant.
 
How the Metro-Grower™ works
The Metro-Grower™ is uniquely designed to use capillary action to draw water up through soil and to take the guesswork out of watering. Plants take the water they need out of the visible reservoir. This way, you can see exactly how much or how little water your particular crops desire. This is a healthy, sustainable way to water your plants. As the water is drawn upwards through the soil into the root systems, it delivers essential nutrients to your plants rather than those nutrients being washed away when you water from above.
In traditional plastic plant pots, roots grow until they hit the inner edge, and then the roots start circling around the pot.  Roots that are circling around a pot are more susceptible to the negative effects of excess heat, drought and disease.  To encourage strong, healthy roots the Metro-Grower™ utilizes air pruning, a physical technique that keeps root growth from extending beyond its nutrient-rich growing media, or circling around its container.  This is achieved by exposing the root tips to relatively dry air and stopping their growth.  The layer of air between the water in the reservoir and the soil separator, air prunes the plant roots. This stimulates further growth of secondary roots that branch out within the growing medium. More roots means more water and nutrient uptake.
Simply place your Metro-Grower™ container on the watering tray and then place the soil separator in the container. The soil separator ensures that your soil is not saturated and you will never experience root rot. In two corners of your container, the soil will dip down into the water reservoir and wick moisture up to your root systems. Add your preferred soil mix and plant according to seed packet directions.
