About Quebec CBD 20-1
Genetics & strain profile
Quebec CBD 20:1 is bred by Quebec Cannabis Seeds and is our highest-ratio CBD strain: 20% CBD and only 1% THC, and also rich in CBG, CBN, THCV and CBDV. It is one of our best sellers, has two grower diaries on GrowDiaries, and its 15 reviews average 4.4 out of 5: “hands down the best CBD flower I have ever had”, a grower in Edmonton whose plant “did fantastic” in a backyard garden with beautiful blue-and-purple buds after cold nights, a customer who can only use high-CBD cannabis and grew two plants “taller than me”, and a grower who got “about a half pound out of two bushes” from small, compact plants. The honest notes are about germination and timing: two reviewers had only 2 or 3 of 5 come up — seeds that do not germinate are covered by our guarantee, so contact us — and two found the outdoor finish later than they expected. The plant also shows two phenotypes: short and bushy, or tall. Our seeds are guaranteed.
How Quebec CBD 20:1 grows
Flowering is relatively short, at around 60 to 65 days, with up to 450 g/m² indoors. Outdoors, expect to harvest around early October with up to 800 g per plant in ideal conditions, but read the reviews for the real-world range: 150 g per plant for a grower who found it ran to the end of October, a half pound from two compact bushes, and one grower who started a seed on July 1 and had to harvest an unripe plant on October 30 before frost. The lesson is to start early — indoors in April, outside in late May — and to pick the sunniest spot you have; the Edmonton grower who germinated in early May and transplanted on the May long weekend harvested in late September. Indoors, one grower who forced a late plant under 12/12 in a cardboard box got there too. It takes topping and defoliation well, and stays healthy; stake the tall phenotype by August. Germination has been uneven for a few reviewers and is guaranteed.
Taste, aroma and effect
Earthy and herbal, with slightly sweet notes, and buds that turn blue and purple with cold nights. With only 1% THC it has very little psychoactive effect: reviewers describe calm and a lift in mood without feeling high, and one calls it the best CBD flower she has had. It suits oils and tinctures, where a 20:1 ratio is easy to dose. This is not medical advice. For 1:1 strains, see CBD Critical Mass and CBD Harlequin; for a random mix of our CBD lines, the CBD Mix Pack; for the whole range, CBD cannabis seeds.

I brought three varieties of high CBD seeds last year and one variety was a free gift. SSkush. Northern lights and 20:1. SSK & NL grew high and great big buds. 20:1 were a completely different plant. Small compact bushy and teeny but plentiful buds. Only 2 out of 5 seeds germinated but I got about a half lb out of both bushes. I love this plant. I cannot do thc anymore and this plant had tested at total CBD 9.8% & no thc. I enjoy the relaxed feeling from the smoke. NL tested 13.9% THC & trace CBD. SSK tested 6 THC & 10% CBD.

I decided late this season to grow the last of the 5 seeds from my 2021 pack. On July 1st, I put it outdoors in a 15 gallon fabric pot. It grew quickly and required more defoliating than the other 4 seeds from the same pack. It grew to 5+ feet tall. I harvested October 30 because of frost but it still wasn't ready. I ended up with very small, immature buds. But when vaped, I get the same effects as last year's, mature crop. Although this strain is tough to finish outdoors in Ontario, I'm very happy with the unique effects and will definitely order it again.

The only cannabis I can use is high CBD, low THC. This year was my first year growing it. I grew 2 plants, that are taller than me. And one started to bud, the other is showing signs of buds. I planted 3 seeds, and one didn't make it. I believe they are the different phenotypes. It came with a bonus seed, which is also growing from a different type. Overall very pleased. A lot cheaper than buying it from nslc. And I should have enough for years after. Thank you.

I planted three seeds only one did not germinate. I was told I had to make another purchase to qualify for the warranty/ guarantee.
We do guarantee our seeds, but yes we will not re-mail just one seed so on your next order you just have to mention it in the note section.

Grew in this lady in my backyard garden in edmonton and it did fantastic. Germination early may, transplant to outdoor garden may long, harvest late Sept with a beautiful blue/purple bud ( colder nights ).. biggest problem was getting a cardboard box big enough to 12/12 her .. lol best prob to have.. I'm here getting more seeds for this season

Montreal Seeds are top notch! I had placed what was a large order for me and waited patiently for ... almost 2 weeks, tracked it and it was sent in wrong direction. I messaged them,they told me they were sending me the whole order right now with some promotional seeds and some other seeds and to keep the original order as well ! To my surprise that came too! Can't wait to get my greenhouse going this year... excellent customer service! Happy New Year

Outdoor grow in Ontario, seed started on 4/20. I did not see flowering until September 4. But when it started, it flowered quickly. I had to cut it down early on October 10. This might be a tough outdoor grow for some regions.
I ended up with 16 mason jars of dried bud and half that in popcorn buds and sugar leaf trim - a lifetime supply.
The effects are terrific. When I’m feeling low, the 20:1 improves my mood. When I feel uncomfortably anxious, it brings me down to a controlled, organized feeling. It is difficult to describe but my perspective changes.
I repeated this a few times since with similar results. For the first time, I understand the hype over CBD. It is surprising how my body responds to this strain. For a plant to have to ability to both elevate the lows and stabilize the highs makes this a life-changer for me. I strongly recommend!

3 of 3 germinated and grew into 4 foot plants with plenty of buds. Each plant gave me about 2 liters of bud when grown in a 4x4 tent with led lights.
