Description
The RootBuilder II container system has many holes with downward facing protrusions all around the container. This design allows roots reaching towards the container wall to locate the air holes immediately.
The downward protrusions make it virtually impossible for the directed roots to escape root tip pruning. Another feature of the angledprotrusions on the containers is that they not only force roots downwardto the air hole for proper air pruning, but they also create shade, keepingyour entire plant’s root system much cooler.
