California Haze by Humboldt Seed Company

California Haze Strain Info

Ever felt like your brain needed a splash of citrus to wake up and get those creative juices flowing?

The California Haze strain might just be the spark you're looking for—born from a legendary mix of California Haze, Original Haze, and Arcata Trainwreck, this Sativa-dominant gem carries the soul of old-school West Coast weed with a twist of modern magic.

We're talking pure Humboldt fire in seed form, straight from the master breeders at Humboldt Seed Company.

These are feminized cannabis seeds, so you can skip the guessing game and grow with confidence—every plant wants to impress.

She stretches tall like she's chasing California sunshine, forming those iconic spear-shaped colas that scream “look at me” even before harvest.

The structure is strong, airy enough to avoid mold, yet stacked with dense, heavy buds that drip resin like a tree full of honeycomb.

California Haze doesn’t just look good—it smells like a citrus grove during golden hour, with sweet lemon zest, fresh pine, and a subtle earthy kick that clings to your senses.

Every bud feels like it's been dusted in sugar, glowing with that frosty trichome armor that growers dream of.

Flowering Time & Yield

This lady's not only a stunner—she’s fast on the trigger.

Expect indoor flowering to wrap up in around 67 days, which is pretty impressive for a strain packing this much Sativa energy.

Outdoor growers should mark their calendars between October 1st and 10th for peak harvest windows.

And when it comes to yield, she delivers like a champ—up to 500 grams per square meter (17.6 oz/ft²) indoors and up to 800 grams (28.2 oz) per plant outdoors.

This isn’t one of those “pretty but picky” strains—it brings both looks and weight to the party.

Effects and Aroma

Imagine lighting up a joint, the first pull hits your lips, and boom—your mind starts to dance.

The 25–27% THC content hits hard but smooth, sending waves of euphoria, energy, and mental clarity straight to your head.

Writers, musicians, coders, daydreamers—anyone who lives in the creative lane—this is your muse in plant form.

It doesn't just lift you up, it opens doors in your brain you forgot even existed.

Perfect for daytime use, social settings, or those moments when you want to get things done with a smile on your face and a spark in your soul.

The aroma? Think lemon candy melted into a forest breeze.

Sweet, tangy, piney, and so fresh it practically dances up your nose—there's no mistaking this for anything but Haze at its finest.

Grower's Tips & What We Love

One of the things we love most about the California Haze strain is how easygoing she is in the garden, without losing that wild, Sativa personality.

She shows impressive resistance to common pests and fungal diseases, making her a solid pick even if you're not working with a perfect setup.

This strain thrives in warm, sunny climates with dry air and long daylight hours, but she can also adapt well to greenhouses or controlled indoor environments.

If you’re growing outdoors, a spot with plenty of sun and good airflow will help her stretch and stack buds without issues.

Indoors, we recommend keeping her under control with training techniques like LST or topping—she loves to stretch and can get pretty tall fast.

We’d say she’s moderate in difficulty: beginner growers can handle her with a little patience, and experienced cultivators will get the most out of her yield and structure.

Give her some love, space to grow, and a good feeding schedule, and she’ll return the favor tenfold.

Frequently Asked Questions

Is California Haze sativa or indica?

California Haze is a Sativa-dominant hybrid, which means it leans heavily toward the traits of a sativa but still carries a touch of indica influence.

Sativas are known for their tall structure, longer flowering times, and uplifting, energetic effects—perfect for creative or daytime use.

Indicas, on the other hand, tend to be shorter, with quicker flowering cycles and more relaxing, body-focused effects.

With California Haze, you get the best of both worlds—vibrant energy from its sativa side, plus solid yields and a slightly faster finish thanks to the hybrid balance.

How long does California Haze take to flower?

California Haze flowers in up to 67 days indoors, which is relatively quick for a strain with such strong sativa genetics.

Outdoors, it’s ready to harvest between October 1st and 10th, before the weather gets too cold in most regions.

Is California Haze good for beginners?

We’d say California Haze is moderately easy to grow, so it’s a great option for beginners who are ready to take on a slightly taller plant and manage its stretch.

Its natural resistance to pests and disease makes it more forgiving than many other sativa-leaning strains.

What kind of climate does California Haze need?

This strain performs best in warm, sunny, and dry climates where it can stretch and stack buds without worrying about mold or mildew.

Greenhouses or indoor setups with strong lights and good airflow also work really well for maximizing yield and bud quality.
