Zourgum by T.H. Seeds

Zourgum Strain Info

If you’re chasing a strain that tastes like sour candy and kicks like a heavyweight, Zourgum is your golden ticket.

Born from a powerhouse cross between Zours and the legendary Original Bubblegum, this limited edition strain by T.H. Seeds is no ordinary batch of marijuana seeds.

It’s a love letter to California’s underground breeding scene, crafted in collaboration with Hall of Flame and released as a feminized cannabis seeds drop—available only while supplies last.

It’s the kind of genetic mash-up that gets connoisseurs whispering and collectors hunting.

At first glance, she might not scream “showstopper” during veg, growing at a slow, steady pace like she’s saving her energy for something big.

But once the flowering kicks in, she goes full diva—stretching tall and wide like she owns the tent, bursting with colors that range from deep green to jet black with shocking pink streaks curled deep into the flowers.

Every bud she throws is dense, sticky, and loaded with trichomes that shine like sugar crystals under the grow light.

The structure is robust, built to stack heavy colas, and by the time harvest rolls around, it’s a visual feast that could make even veteran growers stop and stare.

Flowering Time & Yield

Don’t blink—her show begins fast and wraps up in about 60 to 65 days, just the right tempo for those who want big results without the long wait.

Under good conditions, she delivers a massive indoor haul of around 600 to 700 grams per square meter (21.1 to 24.7 oz/sq ft), easily earning her place in your seed bank.

She reaches a manageable height between 120cm and 160cm (3.9 to 5.2 ft), making her perfect for controlled indoor spaces or discreet greenhouse grows.

This strain isn’t just pretty—it’s a producer, through and through.

Effects and Aroma

Light her up and brace yourself—the first thing that hits is a rush of feel-good euphoria, like popping open a fresh bag of sour candy and getting smacked by a tidal wave of tangy sweetness.

The flavor? Sticky bubblegum meets electrifying sourness, like someone dunked your childhood memories in THC and turned the volume to max.

And once that cheerful high sets in, she pulls you down into a warm, cozy body buzz that makes the couch feel like a cloud and your worries melt like sugar on your tongue.

Perfect for movie nights, lazy Sundays, or winding down after a long day.

This is a strain that says: “Forget your to-do list, we’re chilling tonight.”

Whether you’re battling pain, stress, PTSD, or just want to crank up the appetite before dinner, Zourgum’s deep body high and therapeutic effects hit exactly where you need them.

She’s got that “stay in, snack hard, sleep well” kind of vibe that’s rare to find all in one package.

Grow Tips & What Stands Out

We’ve found that Zourgum responds beautifully to topping, especially if you do it once or twice during veg to encourage her lateral growth and maximize yield.

She thrives in most grow mediums, but if you're chasing those signature colors and resin production, a well-dialed organic soil setup really brings out her best.

Keep your temperatures stable, ideally between 21°C and 26°C (70°F to 79°F), and humidity in check during flower to let her dense buds finish strong without issues.

As for resilience, she's surprisingly tough—strong against pests and molds—making her a solid choice even if your environment isn't perfect.

That said, we recommend her for growers with at least a bit of experience under their belt, since her initial veg phase is slow and requires some patience.

What truly grabs our attention is how dramatically she transforms during bloom—those inky black petals with pink cores are just surreal.

It’s not every day you see a strain that grows like a work of art and performs like a champion.

Frequently Asked Questions

Is Zourgum sativa or indica?

Zourgum is a balanced hybrid with 60% sativa and 40% indica, giving you the best of both worlds.

Sativa strains are known for their uplifting, energetic effects and taller growth structure, while indicas tend to be more relaxing and compact with heavier body effects.

This hybrid leans slightly toward the sativa side, which explains her euphoric onset and expansive growth during flowering, followed by a deeply relaxing body high.

How long does Zourgum take to flower?

Zourgum finishes flowering in just 60 to 65 days, making her a relatively quick strain for such high-quality results.

This short flowering period is great for growers looking to flip cycles faster without sacrificing yield or resin production.

What makes Zourgum visually unique?

One of the standout features of Zourgum is her striking dark black and pink-toned flowers that develop late in bloom.

These colors aren’t just for show—they’re a sign of rich anthocyanins and well-developed genetics that impress both visually and chemically.

Is Zourgum easy to grow?

Zourgum is best suited for growers with some experience, as her slow vegetative growth requires a bit of patience and training to maximize performance.

Once she hits flower, though, she becomes much easier to manage and delivers professional-grade buds with minimal issues.

What growing conditions does Zourgum prefer?

She thrives in a stable indoor setup or a protected greenhouse with mild to warm temperatures between 21°C and 26°C (70°F to 79°F).

Good airflow and humidity control during flowering help her dense buds reach their full potential without risking mold.
