Pot Liners are perfect for both indoor and outdoor gardens. These bags allow growers the ability to really control and manage most aspects of root growth and monitoring. The bags come in a range of litre sizes; 20L, 30L and 50L.
 
They feature woven sides to allow your media to breathe and are netted underneath to prevent water-logging. They even come complete with an easy drawstring to help tie things up once you are finished with the media.
 
For example, we often layer these bags in the following formation; clayballs at the bottom, coco-perlite in the middle and then another layer to protect your growing media from pests that may affect your soil or media.
