Weed Seeds For Sale in Ontario
Let’s face it: the plethora of weed seed banks available in Ontario, and specifically in and around Toronto, makes finding the right marijuana seeds difficult and often confusing. And yet, sourcing the right product is also among the most important choices a grower can make.
Yes, your placement and strategy to grow and nurture the plans all play a role. But without the right genetic seeds, even the best lighting, pest control, nutrients, and other variables won’t make an impact. You need the right seeds to start, meaning you need to find an Ontario seed bank you can trust and with plenty of choices. Enter Weed Seeds Canada.
WSC As Your Canadian Seed Bank of Choice
There’s a reason that growers across Canada and Ontario trust us. In fact, there’s more than one reason. Boasting stable products that reliably produce high yields alongside strong flavors is what’s made Weed Seeds Canada one of the country’s most well-reputed seed banks. We’re high on our cultivars, but for good reason. Four reasons, in fact.
1. Stable, Tested Genetics
We know how much seed genetics matter to growers. You have to rely on the fact that the products you purchase ultimately and reliably develop into high-quality cannabis plants. That’s why we constantly test our seeds, observing them according to precise metrics. We discard any strain that doesn’t meet these metrics, weeding out potentially diseased strains in the process as well.
2. The Region’s Best Selection of Seeds
Of course, a seed bank’s quality only matters if you can get the strains you’re looking for, as well. We’ll put our selection up against any ON seed bank, with options ranging from autoflower to mold-resistant strains, long-flower strains, feminized strains, high-level THC strains, medical CBD strains, and more. Here’s the gist: no matter your need and preference, we have the strain you’re looking for.
3. The Fastest Shipping in Canada
Effective weed growing has to happen on a schedule, and the last thing you want is for the shipment of cultivars to delay that schedule. That’s why we’ve prioritized this part of the experience, with next-day shipping that is unparalleled in Ontario or Canada as a whole. You pick the products you need and before you know it, they arrive at your doorstep ready for growing.

Source Affordable Seeds Ontario
As the weed seed market in Canada continues to expand, it can be difficult to determine the quality of the products you’re buying online. Price is a natural consideration in that process, but not all cheap seeds are quality seeds. Ultimately, you might end up paying more long-term through unreliable seeds through failing germination, increased risk of diseases, and more frequent re-orders.
The legalization of marijuana has, in some ways, turned the market into the wild west. Plenty of disreputable vendors try to get in on the action, and the grower suffers from the low-quality product they get as a result. These red flags can help you determine whether or not the seeds you’re after will hold their promise and potency:
- Seeds that aren’t clearly marked by gender. These seeds are typically hermaphrodites, which means they grow both male and female flowers. That lowers the yield and quality of the harvest, decreasing the efficiency of your growing efforts.
- Unstable seeds whose yield is difficult to predict. It takes an immense amount of testing and quality control to produce stable weed seeds, and many cheap weed banks simply don’t go through that process. Look into the seller’s testing process and how they ensure stability before the purchase.
- Old seeds or seeds that aren’t marked by age. Technically, a marijuana seed can last up to a decade, but that doesn’t mean it’s recommended. The seed will become drier, making it more difficult to germinate. That makes the age of the seeds you’re buying a core factor in choosing the right cannabis bank.
At the same time, the flipside is also true. A low price isn’t an immediate indictment of quality. As you research the seeds you buy, keep reputability in mind. We’re proud of the fact that WSC is the cheapest option in Canada among reputable seed banks, but the reputable piece of that statement is absolutely vital to that statement.
Our emphasis on value for cannabis cultivators also extends to our payment processing. Our e-transfer option works similarly to online apps like Zelle, allowing you to send money using only your email address. Both parties agree to the transfer, at which point it’s irreversible. That agreement counts as purchase confirmation, which kicks off the one-business-day shipping window for your seeds.
The Best Time of Year to Grow Cannabis Outdoors in Ontario
You can hardly wait: those seeds are finally arriving, and you’re starting or expanding your own farm of cannabis strains. But don’t just plant them at any time. Hitting the growing season at just the right time is vital to making sure that those seeds germinate, flower, and ultimately yield exactly what you’re looking for.
As is the case in every region, the weed-growing season in Ontario is affected largely by its climate. Located in Central Canada, the local habitat is affected by three air sources:
- Cold and dry arctic air from the north
- Pacific polar air crossing in from the western Canadian Prairies and U.S. Northern Plains
- Warm, moist air from the Gulf of Mexico and the Atlantic Ocean
These air sources and the resulting climate slightly change the growing season for different regions in Ontario.
In and around Toronto, the time between May and Early October works especially well thanks to mild low temperatures without the fear of bud rot, combined with prime growing high temperatures in the middle of that window. The northern parts of Ontario, like Deer Lake, have a shorter growing season that typically lasts from June to September before the weather gets too cold to grow cannabis outdoors.
This tight growing season window means that cultivators should plant their weed seedlings outside from May to early June. However, it makes sense to begin the seed germination process before that time, developing seedlings indoors in a more controlled environment to build strength and resistance first.
Weed harvesting occurs approximately 50 to 75 days after the cannabis plant flowers. Given the Ontario growing season, that’s typically between mid-September and early October in the southern parts, and early to late September in the northern parts of the province. But don’t harvest the plant before it’s ready; inspect the trichomes for an amber hue, and wait until the leaves start to yellow or curl.
Growing Cannabis Indoors from Seed
Cultivators with the ability and equipment to grow weed indoors face a major advantage. They’re able to set the harvest on their own schedule, potentially beating the outdoor crops sold by most growers and getting a better rate in return before the supply of pot or CBD drops the market price.
That’s because, in the right environment, cannabis can grow around the year in a controlled environment. This controlled environment also results in more potent and higher yields, thanks to equipment that simulates just the right temperatures and lighting for optimum growth.
A few core pieces of equipment can help you build that controlled environment to achieve more consistent, faster growth and yield:
- A grow tent that allows you to create a dedicated space for your cannabis while maintaining set levels in temperature, humidity, air circulation, and more.
- Indoor soil with a pH level between 6 and 6.5 along with the right concentration of nitrogen, phosphorus, and potassium along with calcium, manganese, iron, copper, and sulphur.
- Humidity control equipment, usually in the form of a humidifier and dehumidifier. Ideal humidity levels are 65% for seedlings, which lowers by about 5% every week to around 40% in the final weeks.
- Fans to ensure air circulation and prevent stale, stagnant air that could result in mold and other diseases harmful to your seedlings and weed plants.
- Growth lights that imitate natural light, ideally with a timer that gets your plants on a regular schedule needed to stimulate growth.
- A thermometer and hygrometer that can measure the air temperature and humidity in your growing environment to keep the consistency or adjust your other equipment as needed.
Unlike outdoor growing efforts, cultivating your weed seeds indoors also allows you to take advantage of automations that are specifically designed to improve your growth and produce higher yields. Two of these examples are hydroponics and aeroponics:
- Hydroponics describes the process of growing plants in a water-based nutrient solution rather than soil. First developed for use in outer space, it can be immensely successful for cannabis plants as well, thanks to the nutrient-rich environment allowing the seedlings to grow up to 50% faster and provide larger yields.
- Aeroponics describes the process of growing plants in an air-based environment, without the use of either soil or a water-based nutrient solution. The extra oxygen provided by this freedom allows the cannabis plant to grow faster while using 95% less irrigation than traditional soil-grown plants. It also allows you to grow more weed plants in a smaller location, while the nutrients applied directly to the root result in larger, healthier buds.
The Best Fertilizer for Growing Marijuana Outside in Ontario
Nutrients play an absolutely crucial role in growing healthy cannabis plants and harvesting the best possible pot. That means that, especially if you plan to grow weed outside in Ontario, you’ll need to pay specific attention to the fertilizer you use to get those nutrients to your plants.
Ontario is dominated by five types of soil:
- Organic soil occurs primarily in the northern part of the province, covering approximately 300 miles south of the coastline. It’s rich in nutrients like peat and carbon, remaining sufficiently moist throughout the year.
- Brunisolic soil covers the western part of the province as well as north of Toronto and south of Ottawa. This forested soil is relatively acidic and not rich in nutrients, requiring sufficient fertilizer for consistent growth.
- Cryosolic soil is primarily present in the northwestern part of the province in the tundra and arctic regions of Ontario. It is low in nutrients like nitrogen, potassium, and phosphorus, and will require fertilizer supplementation for growth.
- Podzolic soil occurs largely in the center-south of the province, close to Lake Superior. It is highly acidic, but its accumulation of composted forest matter can make it relatively rich in nutrients.
- Luvisolic soil is especially common south of Toronto but also appears in the center of Ontario. It is low in both nutrients and acidity, requiring significant regulation through fertilizer in order to successfully and reliably grow cannabis plants.
Look for fertilizers that both make sense with these soil types and with the type of plant you’re growing. Nitrogen, potassium, and phosphorus are especially vital nutrients to look out for, and they’re typically labeled as NPK on a fertilizer package. The number next to each initial denotes the intensity of each nutrient, with a higher number indicating a higher proportion.
In the early stages, cannabis plants will require higher nitrogen levels. Especially in soils deficient in that nutrient, like luvisolic and cryosolic soils, a fertilizer with a high concentration of nitrogen (like a fertilizer indicating 3:1:1 for its NPK score) is the best choice. During the flowering stage, potassium becomes a more important nutrient, changing the choice of fertilizer to an ideal ratio of 5:10:7.
Pay attention to micronutrients, as well. Boron, Copper, Iron, Zinc, Chlorine, and Nickel all need to be in the right balance for your cannabis plants to grow. Test your soil for its nutrient level, then look for fertilizer specifically designed to add these nutrients to the mix.
Finally, avoid using fertilizer designed for indoor use in outdoor applications. Organic fertilizers tend to work best outdoors because they integrate better, lowering the risk of upsetting the existing ecosystem. Organic fertilization options include worm casting, blood meal, fish meal, or bat guano for nitrogen; wood ash or keep meal for potassium; and bone meal or rock dust for phosphorus.
Autoflower THC Seeds
Feminised THC Seeds
The Perfect Strains to Grow in Ontario
Ontario’s northern climate and relatively short growing season makes a few cannabis strain types particularly well-suited to the exterior environment:
- Autoflower strains, with their short time to harvest, are great especially in the northern regions offering only a few months of cannabis-growing weather. They’re resilient to harsh environments and offer balanced THC and CBD levels for a variety of medical and recreational uses.
- Feminized strains require longer growth periods, making them better-suited for regions in the south of Ontario. Northern Lights is a common feminized strain thanks to its high THC and CBD levels.
- Photoperiod strains work well in environments with long sun hours and dark nights, making them a great choice in the south of Ontario near the U.S. border but not necessarily further up north. One strain, Barney’s Farm, is particularly popular among southern Canadian cannabis growers.
Keep in mind that these strain types are only relevant for outdoor growing efforts. When cultivating your plants indoors, any strain will work.
Top 3 High THC Weed Strains to Buy ON
Looking to grow plants that just provide a great time and relaxation? In that case, high-THC strains are the way to go. These three weed seed options are especially well-built for the Ontario climate:
- Fat Bastard Seeds. This hybrid indica and sativa strain comes with a THC content of 38%, and a low CBD content of just 2%. It’s a feminized seed that flowers within 8 to 10 weeks, with harvesting occurring another 8 to 9 weeks after the initial flowering. Fat Bastard produces between 400 and 600 grams per square meter when grown indoors, and 700 to 900 grams per plant when grown outdoors.
- Moonshine Cookies Seeds. Another balanced indica/sativa hybrid, the Moonshine Cookies strain contains up to 33% THC and less than 2% CBD. It flowers in 8 to 10 weeks and is ready to harvest in another 8 to 10 weeks, yielding up to 600g per square meter indoors and up to 800g per plant outdoors.
- Gator Breath Seeds. Another feminized strain type with a THC content of up to 33%, Gator Breath also takes the standard 8 to 10 weeks to flower and another 8 to 10 weeks to harvest. Customers love it because of its sweet and fruity flavor profile, while cultivators enjoy yields of up to 450g per square meter for indoor growth and 600g per plant outdoors.
Top 3 High CBD Marijuana Strains to Buy ON
Maybe the medicinal benefits of CBD are more your thing? In that case, you’re in luck. We’re proud to be Ontario’s seed bank, and recommend these three options for ideal growth in the province:
- CBD Super Kush Seeds. The 25% CBD content of this indica-leaning hybrid plant is perfect for medical uses like relieving stress, insomnia, and anxiety. It flowers in eight weeks, with another eight weeks before it’s ready for harvesting. At that point, this feminized plant will yield up to 500g per square meter when grown indoors, and up to 550g per plant in outdoor cultivation.
- CBD Zenergy Seeds. The name is the game for this indica hybrid, whose 24% CBD percentage can almost instantly soothe stress and anxiety along with pain and inflammation. Meanwhile, a less than 5% CBD percentage ensures there will be no hallucinations or psychedelia. It’s a fast-growing plant that produces a yield in just 6 to 7 weeks from first flowering, up to 450g per square meter in indoor environments and 550g per plant when grown outdoors.
- CBD Super 27 Autoflower Seeds. When a strian comes with 30% CBD content and just 1% THC, you know its healing benefits will be significant. Add the fact that this is an autoflower, and you’ll go from seed to harvesting in just 8 to 9 weeks. Autoflowers need to be grown under the right conditions but when you do, you can expect a yield of up to 450g per square meter indoors and 450g per plant outdoors.
The Benefits of Autoflower Seeds
Marijuana growers love autoflower seeds for two reasons. They’re quick and easy to grow, making them ideal whether you’re just starting out or manage a large cultivation operation:
- Shorter Turnaround Times. The average autoflower seed goes from seed to harvest in as little as 6 weeks, making it ideal for the shorter growing season of northern Ontario.
- Easy Plant Management. Autoflower plants typically grow to only 3 feet or less, meaning they can more easily fit into confined environment. They also tend to be lower in maintenance needed during that time.
The combination of these two pieces make autoflowering strains a preferred choice for both volume and management. Options like the above-mentioned CBD Super 27 prove that the quality of cannabis doesn’t diminish as a result.
The Perks of Feminized Seeds
Like autoflower seeds, feminized seeds eliminate the possibility of male plants that would yield smokable cannabis for either THC or CBD. Unlike autoflower seeds, feminized plants are both larger and produce higher yield, making them a better choice for bigger cultivation operations. However, they will also need significantly longer from seed to harvest.
Unlike autoflowers, which take as little as 7 weeks from seed to harvest, feminized seeds typically require between 12 and 20 weeks for the same process. Also unlike autoflowers, they flower when receiving 12 hours or light and 12 hours of darkness a day, making their planting especially outdoors a more strategic endeavor. The reward is a larger plant with higher yields per square meter.
Ultimately, the choice comes down to your preference and situation:
- Beginners looking for low-maintenance plans with fast yields typically look to autoflowering strains.
- Larger, more experienced growers can use feminized strains for bigger and more significant yields.
- Autoflowering seeds are more suited for indoor cultivation, while feminized seeds grow better in outdoor environments.
