High Caliper Growing

Makers of the Smart Pot, High Caliper Growing (with the help of Oklahoma State University) first developed fabric containers for use on a wholesale tree farm in 1980. Inspection of these “bag-grown plants” revealed a highly branched, fibrous root mass — crops grew better! As nurserymen took note, the bag system of growing quickly grew in popularity. It is now used by thousands of customers growing millions of plants worldwide.
