Our Products


Started in 1947 by Bob Peters, this Horticultural Services Co. tested soil for greenhouse growers and made recommendations on how to produce the best crops. Today, under the leadership of Bob’s son, Jack Peters, JR Peters, Inc. is advancing the tradition of Peter’s family quality products and services. Third generation in the Peters’ name, Vice President Cari Peters, of JR Peters took a moment to speak with CannaBiz Journal about how their involvement in the cannabis industry, and where they started from; telling the tale of how a non-cannabis specific business has applied itself to the cannabis industry.
