A patent was recently awarded to a cannabis company with an idea that can save hydroponic gardeners from a host of devastating diseases. The product, COLD-GROW™, uses cold air and temperature differentials to kill and prevent pathogenic bacteria and fungus as well as improve yields and plant quality. Though growing cannabis is illegal, this patent is one of many that has been awarded by the U.S. Patent Office for cannabis-related products.
Patent awarded for COLD-GROW™
According to the patent, using the COLD-GROW™ method doubles the yield and flower quality by treating the hydroponic solutions with cold air in the right place and at the right time. COLD-GROW™chills the plant shoots and the hydroponic nutrients with apparently impressive results.
Interestingly, the patent itself contains cannabis-specific language. The patent describes:
Two groups of four genetically identical C. indica L. (cuttings) were placed in identical growing environments with both group’s root temperature being placed at 75°F. The first group’s shoots were maintained at 75°F…while the second group’s shoots were transitioned to and maintained at 55°F … during the first third of vegetative growth.
…after the first 30 days, the [second] group had main stems approximately 15 to 20% taller and 100 to 150% thicker than the [first] group. Also observed was the higher internodal lenghth and moderately thick and tough leaves when compared to the [first] group.
By the time harvest rolled around, the buds from the second group were 100 to 180 percent larger than those from the first group, which wasn’t treated with the COLD-GROW™system.
More cannabis patents than ever
The patent was announced by SAINT-brand on April 20th, adding itself to the growing list of newly patented cannabis technologies. Interestingly, though cannabis cultivation is illegal, it’s not illegal for companies to apply for patents on cannabis-related products and, in some cases, specific strains.
The Patent and Trademark Office has even granted intellectual property rights to companies that have developed cannabis strains for industrial purposes. Earlier in March of 2017, the Patent Office awarded a patent to Florida-based Teewinot Life Sciences for the development of “apparatus and methods for biosynthetic production of cannabinoids“.
Basically, Teewinot can now produce lab-engineered cannabinoids in the laboratory and sell them around the globe. Other growers and producers have been seeking patents on strains and grow technologies and the race for intellectual property rights are gaining speed.
In 2015, Californian growers were granted a patent for the breeding, production, and processing of specialty cannabis that contained THC. The strain had a specific genotype and produced at least three percent THC and greater than three percent CBD.
Yet, while these growers were able to patent a specialty strain, and businesses can openly disclose the inventions intended for cultivating the herb, the plant still remains federally illegal in the country.
Banking restrictions and taxation issues aside, more and more businesses, like SAINT-Brand and COLD-GROW are legitimizing their products by entering them into a competitive and visible marketplace.
Business is moving full-steam ahead. Let’s hope meaningful political reform catches pace soon.
