Choosing Seeds

Feminized seeds flower and grow weed when they receive less than 12 hours of light per day. Harvest outdoors in fall, or indoors after 15-20 weeks. Professional growers use these.

Autoflower seeds grow small, easy-growing plants that you can harvest in 10-14 weeks. Great for new growers, small spaces, and multiple harvests per season!

How To Germinate

Germination is guaranteed when you soak the seeds in water up to 72 hours in darkness. When it shows a tail, put it in loose soil with fertilizer. Keep it light and damp and a seedling will appear!

Grape Octane Autoflower origins

While this hybrid is usually indica dominant, the Grape Octane we sell is balanced perfectly at 50/50. Cannarado Genetics first bred grape Octane by combining Grape Pie and High Octane OG. Both of its parents are indica-dominant hybrids.

Is Grape Octane Autoflower indica or sativa?

Though typically indica dominant, our Grape Octane feminized seeds are balanced at 50/50.

Growing Grape Octane Autoflower

At the moment, there isn’t much information on growing Grape Octane. However, our feminized autoflowering version is easy to grow. Like the photoperiod version, these feminized seeds are disease-resistant, mildew resistant, and can handle the occasional cold temperatures. They also flower automatically and stay at a manageable height.

What are autoflowering seeds

These are feminized, autoflowering seeds. Female plants, contrary to male plants, actually produce bud. On top of that, autoflowering seeds don’t require light deprivation to start blooming and are ready to harvest in 10 to 14 weeks. We advise checking our germination instructions for guaranteed results.

The best climate for Grape Octane Autoflower

Grape Octane prefers a Mediterranean, sunny climate or a greenhouse for best results. However, our Grape Octane autoflower seeds can also grow in a variety of other temperatures, such as continental and temperate climates, where the temperature drops at night.

We recommend giving your plants:

How tall does Grape Octane Autoflower grow?

Photoperiod Grape Octane plants can reach over 7 feet when grown outdoors, while average outdoor heights are between 60-80 inches. Autoflowering plants may stay shorter due to a shortened vegetative period. Indoor plants may reach up to 5 feet (47 to 59 inches). Growing variables such as medium and lighting will impact the height of your plant.

How long does it take to grow Grape Octane Autoflower

Grape Octane Autoflower seeds take a couple of days to reach the seedling stage. The seedling grows into a full plant during the vegetative phase, which lasts for 7 to 8 weeks.

Grape Octane Autoflower flowering time

Grape Octane Autoflower seeds automatically enter the flowering stage regardless of light exposure. Cultivate your plants in 12 to 14 weeks; however, this may vary depending on the climate and the amount of light per day.

How much does Grape Octane Autoflower yield?

Grape Octane Autoflower seeds produce Cannabis plants with 5 to 15 ounces yields. Individual harvests will vary based on whether you grow indoors or outdoors and how you care for the plant. Low-stress techniques, like increased lighting, optimized growing mediums, and pruning, can encourage a higher yield.

Experiencing the Grape Octane Autoflower strain

Grape Octane is a true hybrid that doesn't produce typical indica or sativa effects. Unlike many indica strains, you won’t feel couch-locked or immediately ready to sleep; and unlike most sativa strains, Grape Octane won’t cause you to feel jittery or anxious. Instead, the overall effect is high-powered and recharging, keeping you both relaxed and ready to go.

Grape Octane Autoflower THC level

Although THC levels have reached 29%, most Grape Octane growers can expect levels between 23 to 26%. CBD levels are low at less than 1%.

Grape Octane Autoflower terpenes

Limonene is the dominant terpene in Grape Octane. Myrcene and caryophyllene are also present. Despite the dominant lemon terpene, you may not even notice it, but you will feel its euphoric and creative effects.

Grape Octane Autoflower flavor and smell

Expect Grape Octane to give off an aroma similar to chemicals or ammonia due to its High Octane parent. Smokers may also experience citrus undertones on the inhale and a peppery, spicy flavor on the exhale.

Grape Octane Autoflower effects

Simply put, Grape Octane can do it all. This strain can lead to euphoria, relaxation, and lifted happiness. Some also use it to stifle anxiety or bring about some good vibes after a hard day. You may even feel aroused or sleepy after partaking. Keep some water on hand as it may cause dry mouth and eyes.
