From growing indoor or outdoor to key pitfalls in cannabis propagation, Bill MacDonald of Niagara College talks cannabis production. How similar is it to growing other horticultural crops?
Ian Davidson doesn’t mince words when talking about opportunities in the cannabis nursery game right now. “They’re profound,” says the 15-year industry vet. “There are cannabis specialists in extraction, in packaging, in marketing, you name it, but show me a single operating cannabis nursery in Canada.”
As global demand for medicinal cannabis continues to increase, PharmaCielo Ltd. is poised to become an international leader after receiving approval on February 6th and 19th in Colombia for the listing of 20 proprietary and unique tetrahydrocannabinol (THC) and cannabidiol (CBD) strains with the national cultivar registry.The Canadian-headquartered company will now be able to produce—through its Colombian subsidiary—Colombia’s only CBD-dominant strain that meets World Health Organization (WHO) purity standards. The approval gives PharmaCielo a competitive advantage as the sole licensed producer of non-psychoactive strains in Colombia. A fully balanced THC/CBD strain was also approved, among the many others.Federico Cock-Correa, President and CEO of PharmaCielo Colombia Holdings S.A.S., says the company can now proceed to commercial registration, production and sale of these strains within Colombia, as well as for export to global markets.“Among those approved is an historic and unique CBD-dominant strain approved for commercial registration and sourced from the Colombian landrace strains held within our fuente semillera (a licensed seed or germplasm bank authorized by the Colombian government), the first and only one of its kind registered in Colombia,” Cock-Correa noted.The commercial value of this 20:1 CBD primary strain is of “particular significance with the recent clarification by the WHO that medicinal CBD is not regulated under international convention,” says Dr. Delon Human, PharmaCielo’s global head of health and innovation.“The intensity of the CBD strain profile allows us to efficiently fulfill strong global demand for pure CBD medicinal cannabis oil extracts, which we expect to dramatically increase over the next several years for this strain, as it meets both market and import requirements,” adds Dr. Human.Since its founding, PharmaCielo has focused on ethical and sustainable processing and supplying of all natural, medicinal-grade cannabis oil extracts and related products to large channel distributors.In January this year, the company established a joint venture with Mino Labs to bring medicinal quality cannabis oil to Mexico. The company also went public in recent months on the Toronto Stock Venture Exchange (TSX Venture) through its Canadian parent company.

With greenhouse vegetables, there are many different varieties available. Each one is selected for higher yields, larger fruit, disease resistance, flavour and more, but how well do those attributes hold up in the greenhouse?
