Producing premium cannabis starts with genetics, but what happens once a cultivar enters the facility is just as important.
In Episode 32 of the GroShow Podcast, Brandan Leroux, Head Grower at Sublime Culture, joins Grodan Crop Specialist Chad Rigby to talk about what it takes to turn genetic potential into consistent commercial production and eventually meet the expectations of international markets.
Brandan also shares his path into commercial cultivation, from his background in plant science to the mentors and experiences that helped shape how he approaches growing, managing teams and running a commercial operation today.
Based in Laval, Québec, Sublime Culture approaches cultivar selection by looking beyond any single metric. Flavour, aroma and overall flower quality have to be considered alongside plant structure, yield and consistency.
From there, the discussion gets into the root-zone. Brandan and Chad break down how crop steering, irrigation strategy, root-zone EC and dry-back can be adjusted across different cultivars, and how Grodan stone wool and GroSens data help support those decisions throughout the crop cycle.
The conversation also looks beyond the facility. Sublime Culture is already active in the cannabis export market, giving Brandan firsthand insight into what international buyers value and how expectations around genetics, consistency, flower quality and post-harvest handling can differ from the Canadian market.
What ties it all together is the idea that premium quality is rarely the result of one decision. It comes from aligning genetics, cultivation strategy and execution from the root-zone through to the finished flower.
For cultivators interested in cannabis genetics, crop steering, root-zone management and international cannabis markets, this episode offers a practical look at how Sublime Culture is approaching each of those areas.
