Anesia Seeds

Who is behind Anesia Seeds

Anesia Seeds was born in Austria. It was founded by Tanja and her partner, and Tanja is now the face of the brand and its lead breeder. Today the seed bank is based in Reus, near Tarragona (Spain), and has been creating strains for more than 15 years.

The catalogue started as a collection. Tanja travelled through the United States, India and other parts of Asia, talked to breeders and gathered rare, very potent strains. What began as a personal passion drew more and more attention until it became a company, and not even she saw that coming: in a 2025 interview she said that at first she had no idea how popular Anesia would become. When she founded it, a lot of people advised her not to. Today she's glad she didn't listen.

Anesia works as an independent seed bank. Its priorities, according to Tanja, are stability, resistance and very distinctive flavour and aroma profiles. The brand sells two types of seeds: feminized, which only grow female plants, and autoflowering.

Anesia's best sellers at Oaseeds

These figures come from our orders over the last 12 months, with customers in 23 countries:

1. Think Tank: almost 1 in 4 Anesia orders includes it. According to the breeder, it's the strain with the most THC in the catalogue.
2. Frozen Black Cherry: the second most ordered, with a cherry flavour. It was a finalist for best strain at the 2025 Grow Awards.
3. Core Damage: new in 2026 and already in the top three. It's the child of the two most famous strains of the house, Think Tank and Future #1.
4. Grape Pop Rocks Auto: the best-selling autoflower. It takes 60-65 days from seed to harvest.
5. Honey Fried Bananas and Sun of a Peach, tied: the pick for growers in a hurry, because both flower in 7-8 weeks. Sun of a Peach tastes of peach and lemon.

Anesia strains compared

THC, growing time and yield figures provided by Anesia. Yield is given in grams per square metre, meaning how much you harvest indoors for every square metre of grow space.

Look at the "Time" column. For feminized strains it only shows flowering, the final stage when the plant forms its buds, and you need to add a few weeks of growth before it. For autoflowers it shows the whole cycle, from sowing the seed to harvest.

Which Anesia to choose for your grow

If it's your first grow

Start with an autoflower. These plants start flowering on their own after a few weeks, without you having to change the light hours, and they're more forgiving of mistakes. Grape Pop Rocks Auto is the best seller and is ready in about two months. Frozen Black Cherry Auto gives you the flavour of the famous feminized version in less time.

If you already have some experience

To get to know the brand, Tanja recommends Glowberry Rush. It's a feminized strain with 8-9 weeks of flowering and, according to the breeder, the highest indoor yield in this table.

If you want maximum potency

Think Tank is the benchmark, with a stated 41% THC. Core Damage and Roswell Code follow, with up to 39%.

If you're short on time

Honey Fried Bananas, Sun of a Peach and Roswell Code flower in 7-8 weeks, among the fastest feminized strains in the catalogue.

If you're into original genetics

Anesia also has a small line of landraces, traditional strains that grew for centuries in one place without being crossed with others: Afghanica, Hindu Kush, Malawi Gold, Panama Red, Pure Durban and Congo. They're all feminized.

The family tree of the house

Many of Anesia's new releases come from crossing its own strains instead of buying genetics elsewhere. Here's how one strain leads to the next:

• Blackberry Moonrocks was crossed with Pacific Frost to create Frozen Black Cherry. That one was then crossed with Blueberry Gumbo to create Glowberry Rush.
• The two most famous strains of the house, Think Tank and Future #1, are the parents of Core Damage.
• Imperium X was crossed with Violet Fog to create Indigo Sapphire, with very dense buds.
• Blackberry Moonrocks was crossed with Brownie Scout to create Umme, with a sweet blueberry aroma.

How potent is Anesia?

THC is the compound in cannabis that produces the psychoactive effect, and it's Anesia's big signature: many of its strains go above 30%. These are the figures the seed bank gets under optimal conditions, so in your grow the final potency will also depend on light, watering and the care you give it.

A fun fact: online you'll read that a "Future" broke a THC record in Oregon (USA) in 2018. The Oregon press credits that plant to another breeder, Exotic Genetix, even though it shares its cross with Anesia's Future #1.

That's why we recommend choosing your Anesia for its flavour, yield and growing time too, not just its THC number.

How to tell if your Anesia seeds are genuine

Anesia itself warns that there are a lot of fakes around: at fairs and in online shops you'll find packs with its strain names that contain something else. Every original pack has three signs:

• A hologram on the back of the pack.
• The seeds inside a sealed tube.
• A QR code that takes you to the strain's official page on Anesia's website.

If your pack is missing any of the three, be suspicious. Anesia even registers some strain names as trademarks, such as Future #1®, Blackberry Moonrocks® and Sleepy Joe®.

What growers say

On GrowDiaries, a website where growers post step-by-step logs of their grows, Anesia ranks 14th among all seed banks. It has around 758 harvests and more than 1,100 published grow diaries, roughly 70% feminized and 30% autoflowering strains (figures checked in November 2026). You can read the diaries here.

At the Grow Awards, GrowDiaries' own awards, Anesia was a finalist for best seed bank and best autoflower seed bank in 2025 and 2026, and Frozen Black Cherry was a finalist for best strain in 2025. So far it hasn't won any of those categories.
