Kolos Tang - Grown+ The Grown+ hookah bowl is designed and produced by Russian hookah company Kolos Tang. It is molded and glazed by hand, offered in a number of beautiful colour combinations. Although similar to the regular Grown bowl by Kolos, the Grown+ features four notches on the phunnel which serve to increase airflow quality. These bowls are made of high quality clay and fired with milk to achieve a glazed look. The glaze prevents flavours from staining the bowl, which allows the flavour used in each session to remain pure.
