Bubble OG strain at a glance

What is the Bubble OG strain?

Bubble OG is an original QCS strain: Quebec Cannabis Seeds is its original breeder, and these are our own genetics, bred in Quebec since 2015 by a grower with more than 35 years of experience.

The Bubble OG strain is a QCS original that mixes three famous parents: Bubble Gum, OG Kush and Skunk #1. Each brings something different. Bubble Gum is the sweet, candy-like parent that growers have loved for its flavour for decades. OG Kush adds the pine, fuel and earthy depth that made the OG family famous, and Skunk #1 contributes vigour, a classic skunk note and reliable resin.

The result, according to our product page, is a big, productive mostly indica hybrid with dense buds. It leads with sweet bubble gum flavour and rounds out with pine and skunk. It handles Canada's shorter, colder seasons well enough for outdoor growing in much of the country, which is why it fits the QCS Originals range.

Other seed companies sell strains with similar names, such as Bubblegum OG Kush or OG Bubble Gum, and these use their own genetics. Other seed companies' versions may differ; the figures on this page are for the QCS version only.

Is Bubble OG indica or sativa?

QCS lists Bubble OG as mostly indica, without publishing an exact percentage. Two of the three parents (OG Kush and Skunk #1) are generally described as indica-leaning, and Bubble Gum is commonly described as a balanced to indica-leaning hybrid. That fits with an effect that starts uplifting and settles into comfortable relaxation.

"Mostly indica" does not mean "small". Our page rates the strain moderate in difficulty mainly because the plant gets big and needs managing. If you want to understand more about how indica-leaning cannabis typically feels, read our guide to what indica does to you.

Smell and flavour

QCS lists the flavour as earthy, pine, skunk and floral, with sweet bubble gum up front. That mix of candy and fuel is a hallmark of Bubble Gum and OG crosses. The first thing you taste is sweet and bubblegum-like, followed by the pine-and-skunk backbone that OG lovers expect.

It is not a quiet plant. Expect a noticeable smell in flower and as the buds dry. A carbon filter indoors and some distance from neighbours outdoors are sensible precautions.

Bubble OG effects

QCS describes the effect as an uplifting, euphoric rush that settles into comfortable relaxation. It is indica enough for the evening but not sleep-inducing, which is a pattern consumers often report from OG-style hybrids. A reviewer who tried it among six strains ranked it as one of the best for bag appeal and yield.

As always, effects depend on the person and the dose. At 23% THC, start low and wait before taking more. Nothing here is medical advice.

How strong is Bubble OG? THC content

QCS lists Bubble OG at 23% THC. CBD is not listed on the product page. That is a strong strain by everyday standards, but it is not among the highest in our catalogue. If you want more, browse our THC over 25% seeds.

As with all cannabis, final potency depends on the phenotype, the growing conditions and how well the buds are dried and cured.

Growing Bubble OG: flowering time and yield

Indoors, Bubble OG flowers in 8 to 9 weeks and produces dense buds at 500 to 700 g/m². Outdoors it grows tall and finishes in late September to early October, with yields of up to 700 g per plant. These are ranges, not guarantees. QCS rates the difficulty as moderate, mainly because of the plant's size.

A reviewer shared practical advice that matches what experienced growers commonly recommend for tall OG-style plants: top the plant once it reaches about two feet, support the branches, and thin the small inner branches for airflow, especially in wet weather. Dense buds hold moisture, and our product page reminds growers that "mold resistant" really means mold tolerant, since no strain is fully mold resistant.

One report on our page describes a plant grown outdoors in northern Canada that reached 8 feet, produced 16 colas and 690 g dry and was harvested on October 24 after surviving a windstorm. Treat that as an individual result, not an average. Another reviewer topped his plant four times and it still reached about 6 feet outdoors.

What customers report

Bubble OG has two reviews on our site and averages 4 out of 5. That is a small sample, so use it as a snapshot rather than a verdict.

• Bag appeal and yield: a grower who received it as a freebie ranked it among the best of six strains he tested, with good bag appeal and yield.
• Height: the same grower found it grew tall and, after four toppings, still reached about 6 feet outdoors.
• Germination: a customer reported that a previous order had only three of seven seeds germinate and asked us to make it right. Our germination guarantee covers this: if fewer than 80% germinate, we send replacements. Contact us and we will help.

Our product page also links to several public grow diaries, which are a good way to see real plants through to harvest.

Is Bubble OG right for you?

Choose Bubble OG if you want a sweet-and-skunky, mostly indica hybrid with strong yields, and you are comfortable topping and supporting a big plant. It suits experienced beginners and intermediate growers, outdoor growers in Canada who need a late September finish, and anyone who likes OG-style flavour. It is not the best match if you need a small, easy plant or a very high-THC strain.
