Cannabis Seeds Canada

Great Quality Feminized Cannabis Seeds in Canada

You can just call us Cannabis Seeds Canada now because we have the best quality cannabis seeds in the country. We’re going to be constantly adding new strains over the coming months. Now that it is legal to grow up to 4 plants in your home in Canada (make sure to check your local bylaws!), we want to encourage you to grow your own!

What will I need to start growing my own weed?

You can start with very little, or with a fully decked out operation costing thousands of dollars. At the minimum, you need soil, water and sunlight! Here is a great writeup on getting started with a small indoor grow.

How big can cannabis plants grow?

Fully grown Cannabis Sativa plants can stretch to extraordinary heights of up to ~20 feet tall when grown outside or in a large green room. With proper pruning, it is very easy to keep plants as low to the ground as you need.

Are LED grow lights good or bad for growing weed?

LED grow lights work well when you use them as intended. That means utilizing the proper wattage output for your plants, hanging your light at the proper height, and giving your light a chance to rest after 18 hours of use. With LEDs being a somewhat new technology, some old school growers may still be skeptical or curious if LED grow lights work. You don’t need to look far to determine the answer is a resounding yes.

What are the advantages and disadvantages of growing hydroponic weed?

Growing medical marijuana using hydroponic growing techniques has its perks and downfalls, including:


  • Much bigger yields than the previous methods.
  • Cleaner because no soil is used.


  • Costs a lot more because it requires troughs, pumps, and reservoirs to hold the water/fertilizer mixture.
  • Requires a lot more labor. You will need to monitor pH and nutrient levels to make sure they stay within proper limits.
  • It takes more equipment. Therefore it may take more room.

Highest THC Strain

1. Girl Scout Cookies Strain

With this choice, you’ll get big, robust plants generously coated in large, swollen buds hardened with more than enough resin to make them feel surprisingly heavy in your hand. The strong, heady aroma adds to the exceptional bag appeal of Gorilla Glue’s dried flowers.

  • Yield: Lower
  • Price: $65/5 seeds
  • THC Level: 25%+

Easy to Grow

2. Moby Dick Strain

Growers appreciate Moby Dick’s reliable performance, relatively short flowering time, incredibly high yields and high resistance to mold. The extra THCV in Moby Dick accentuates the THC pushing the psychoactivity of the finished product further than you’d expect.

  • Yield: High
  • Price: $65/5 Seeds
  • THC Levels: 20%

Best For Outdoor Growers

3. Green Crack

After seven to nine weeks of flowering, this cannabis strain will produce a moderate to high yield of light-green buds with purple crystals. While it can be grown indoors and is prized for its high turnaround time, it does extremely well outside as well. It does best in a warm climate, which helps it thrive, and it can withstand most types of inclement weather.

  • Yield:  Average
  • Price: $65/5 Seeds
  • THC Levels: 16%

I'm very pleased with the service I've received from Blue + Yellow. Delivery was fast, and the product (Zero THC) has helped from the first night. I will be ordering from here again.

Best Cannabis site I’ve ordered from. Service was quick(ordered Friday and came home to my order Monday.) great selection and customer service. Highly recommend. 👌
I'm new to all this, figured it's time to try some alternatives to prescription drugs. Having no idea where to begin, I asked a colleague (who's a boffin on weed extracts) - he said use "Blue and Yellow". I was nervous - because I'm old school, so I don't really want my name associated with Cannabis products. However, I am looking for relief for some conditions that have developed over the years .Anyhoo, there's no one-fits-all formula in alternative medicine, so I'm trying to figure out what will work for me. What I love about Blue+Yellow is the simplicity of looking for and understanding products. Once you've decided what you want, their service is streamlined and efficient. In this day and age of instant, they are about as close to instant as you can get. Payment is simple and not on CC, which I prefer, delivery is discrete.Recently, I made a huge mess of a payment, the guys at B&Y were helpful and patient - all my fault :-/, was quickly fixed... Things were on their way in no time at all. I strongly recommend them.

Blue+Yellow is the best place to order any cannabis related products. I have epilepsy and their hybrid blueberry cbd tincture has been amazing. It relaxes me and comes into affect quickly. One of the best things about this company is they’re very friendly and they make sure that your product comes to you fast. I couldn’t ask for anything more. I’ll never buy from anywhere else! Thanks Yellow+Blue!
