All Natural Cannabis
We stand by the “Pure” in Pure Sunfarms.

We believe a product made through natural means is best, and we’ve designed our entire system around growing cannabis in the most natural way we can.
We know it’s important to the people that enjoy our product, and we want them to know that it’s important to us, too. That’s why we put it right in our name.
But what’s so natural about our process? We’re glad you asked.
There are four pillars to our natural growing practices: an all-natural growing medium, natural plant food, our Integrated Pest Management techniques, and harnessing the power of natural sunlight, water, and CO2.
Growing with Natural Materials
We take clippings from our beautiful mother plants, and grow them into seedlings, this process is known as “cloning.” Once the seedlings begin sprouting their own roots and leaves, they are hand planted into a growing medium called “coir,” a fibre made from coconut husk. Coir is completely natural, clean, and compostable. It’s pest and disease resistant and retains water and nutrients exceptionally well.
Each of our plants will spend the rest of their life cycle growing in coir in our flower rooms, where our team constantly monitors the light, temperature, and humidity. In their final few months, their flowers will develop and mature, growing more potent and flavourful day by day, until they’re harvested.

A Healthy Diet
Just like humans, plants need a healthy, balanced diet to thrive. To ensure our plants get exactly that, our team mixes our specialty plant food on-site. Our proprietary recipe includes large amounts of three nutrients—all plants require––nitrogen (N), phosphorous (P), and potassium (K). These are the same basic nutrients that all fruits and vegetables you consume need to grow, including tomatoes, cucumbers, peppers, and lettuce. We also feed our plants smaller amounts of calcium, magnesium, sulfur, iron, manganese, zinc, boron, copper, and molybdenum to round out their nutrition. We deliver this food in liquid form to promote the development of roots, lush foliage, and flowers.
Once the plants reach maturity they’re about a week away from harvest. At this point we flush them of excess nutrients by reducing their diet and continuously feeding them pure water. Plenty of nutrients are great in a young plant, but over time nutrient surpluses build up. Clearing out excess minerals leaves behind valuable salts that the plants turn into extra energy to form a more potent, flavourful bud and a smoother-tasting final product. Like a final burst of energy on a sprint to the finish line, it makes our product just that much better.

Getting the Best of Pests
Getting the Best of Pests
In 2020, we commissioned a survey to find out what Canadian cannabis users wanted to know about their cannabis. The survey showed that 80% of Canadians would prefer cannabis grown without chemical pesticides, but only 40% actually knew whether their cannabis was grown with these pesticides. We hope to change that by continuing to spread the word about our innovative approach to pest management.
We believe that with modern technology and techniques, there’s no need for toxic chemical pesticides or fungicides to come anywhere near our cannabis. But you may be wondering then, how do we deal with pests? As any grower knows, wherever you find plants, you’ll also find pests. Instead of opting for synthetic chemicals to manage these pests, we implement a world-class Integrated Pest Management (IPM) program. For example, we use safe biopesticides and biologicals (including good bugs!) to keep the bad bugs in check, no synthetic or toxic chemicals necessary.

Working with Nature
Pure Sunlight
We’ll never make a light more powerful and nurturing than our sun, so why try? As a modern greenhouse situated in the sunny Fraser Valley of British Columbia, our entire growing system is specially designed to soak up the sun’s natural rays. This allows us to grow in the way nature intended, and only supplement with artificial light when necessary.
For the most part, we can depend solely on pure, natural sunlight to nurture happy and healthy plants. In an average year, our greenhouse captures about 1,900 hours of sunlight or about 286 days of sun. That’s a lot of sunshine.
Rainwater
We also collect the natural rainwater that falls on our greenhouses and store it in a tank until it’s used to irrigate our plants. This being the Pacific Northwest, that’s a lot of water. During the winter when, as any local will tell you, rain is a constant, we put that drizzle to work and primarily use rainwater to irrigate. Thanks to this, we draw very little water from our local water supply.
Cycling CO2
After sunlight and water, the third ingredient in our plants’ photosynthesis recipe is carbon dioxide (CO2). The supplemental CO2 we pump into our greenhouses is a by-product of our heating system. This CO2, which is vital to the photosynthesis process, would otherwise be vented out and dissipated in the atmosphere. By harnessing the CO2 we’re generating anyway, our plants grow bigger, healthier, and faster, and produce a superior quality product, and we squeeze every drop of energy from our system.

A Growing Legacy
Our natural growing philosophy is informed by our team of legacy growers who have been cultivating cannabis in BC for decades, and greenhouse experts who’ve been growing vegetables right here in the Fraser Valley for over 20 years. As we continue to evolve, so does our process, but keeping things all natural is always at the root of what we do.
