High Caliper Growing (formerly Root Control, Inc.) was incorporated in Oklahoma in 1984 and was instrumental in the development of fabric containers (Root Control Bag™, or RCB) for the tree nursery industry. Since that time, High Caliper Growing has gained thousands of customers growing millions of plants, in all fifty states and a number of countries worldwide.
The High Caliper™ Growing System is a high quality - low cost system of tree and shrub production. Featuring the RCB-In Ground and the RCB-Above Ground containers, the High Caliper™ Growing System promotes natural pruning of the roots and permits heat release through evaporative cooling, all of which enhances the root growth and structure. These key attributes translate to improved production methods for the grower, in addition to accelerated yields and greater transplant survival.
In 2011, High Caliper Growing introduced the Smart Pot™ products for the home gardener. All of the horticultural benefits provided from a fabric container are now available to both master and casual gardeners.
