Our History
In 1982 Gary Hartman developed and commercialized the use of Stabilized Growing Media (The Q Plug) for his own nurseries. This form of growing media solved the problems for automation, eliminated shipping and handling problems, and significantly enhanced the rooting of very difficult plants.
Today the Q Plugs and Excel Plugs are available for everyone in a large selection of sizes and shapes. Originally the growing mixes were designed for just rooting and transplanting, but now the media mix has been changed to enhance the actual growing of plants.This technology is the result of four generations of experience and testing and is now incorporated in most of our plugs and soil products.
Development Process
The development of IHORT’S open bottom growing trays and air pruning Ihort Grow Blocks has opened a whole new field of products and growing technologies. Twisted and curling roots have long been a problem of our industry, but with IHORT’S technologies twisting is no longer a problem.
There have been a lot of discussions and products that have come into production to prevent twisted roots, but all of them we know of have all come from the ideas and technologies developed from one of Gary Hartman’s original posters submitted in 1985 to the AHS (American Horticultural Society) on the benefits and technology of air pruning.
