Sensi Research

About Sensi Seeds Research

Most people know Sensi Seeds. Founded in Amsterdam in 1985 by Ben Dronkers, it’s the seedbank behind Skunk #1, Northern Lights and Jack Herer – strains that shaped the whole industry. Dronkers spent years travelling the world collecting genetics before opening the first Sensi shop in Amsterdam’s Red Light District, and the gene bank he built became the foundation for much of modern cannabis breeding.

Sensi Seeds Research is a separate line from that main catalogue – deliberately so. The idea when it launched in 2019 was straightforward: take Sensi’s unmatched genetic library and start crossing it with the new-wave varieties that have changed what growers expect from cannabis. That means taking a legendary cultivar like Silver Haze or OG Kush and working it with something modern, something the global cannabis community has been excited about for the last decade.

The Research programme is also community-driven in a way the main Sensi brand isn’t. Growers can give feedback on new releases, and the community has even participated in naming strains. It started with eleven varieties and has grown steadily, with names like Mandarin Punch, Banana Kush Cake, Purple Skunk Auto and Sensi Amnesia XXL among the fan favourites that have come out of the project. There are CBD-to-THC balanced varieties in the mix too – Skunk Dream CBD being one of the better-known examples.

The Research team is led internally at Sensi – the same Amsterdam operation that’s been breeding cannabis longer than almost anyone else. That depth of knowledge underpins everything, even the most experimental crosses.

What’s in the Sensi Seeds Research Range?

Modern Hybrid Feminized Seeds

The core of the Research catalogue is feminized photoperiod hybrids – new crosses that blend Sensi’s classic gene stock with contemporary varieties. These are strains you wouldn’t find in the main Sensi catalogue: bolder flavour profiles, modern terpene expressions and genetics that reflect where cannabis has gone since Amsterdam’s golden era. Mandarin Punch and Banana Kush Cake are good examples of the direction.

Autoflowering Research Strains

The Research programme includes autoflowering varieties too. Purple Skunk Auto has been a popular one – it takes a classic Sensi shape and runs it in an auto format, giving growers a faster route to something with genuine genetic heritage behind it. These aren’t afterthoughts: they go through the same development process as the photoperiod lines.

CBD and Balanced Varieties

There’s a handful of CBD-rich and balanced CBD:THC strains in the Research range. Skunk Dream CBD is the best known – a variety with meaningful CBD content built on a classic Sensi backbone. Good for collectors who want the Sensi heritage in a different format.

Frequently Asked Questions

What’s the difference between Sensi Seeds and Sensi Seeds Research?

Sensi Seeds (the main catalogue) focuses on established, classic genetics – the varieties they’ve been refining for decades. Sensi Seeds Research is a separate, newer line launched in 2019 that pushes into more experimental territory, crossing Sensi’s classic gene stock with modern cultivars. Think of it as the R&D wing of the same operation.

When did Sensi Seeds Research launch?

The Research programme launched in 2019 with eleven strains, and has been adding new genetics regularly since. It’s a growing catalogue with an ongoing release schedule rather than a fixed, finished range.

What are the most popular Sensi Seeds Research strains?

Mandarin Punch has been one of the standout releases, known for its fruit-forward terpene profile. Banana Kush Cake, Purple Skunk Auto and Sensi Amnesia XXL are other fan favourites. Skunk Dream CBD is worth looking at if you’re interested in balanced CBD varieties. Browse the full range at SeedMasters.com to see what’s in stock.

Is Sensi Seeds Research good for beginner growers?

Some of the autoflowering varieties are accessible for beginners – they’re simpler to manage since they don’t require a light schedule change to trigger flowering. The photoperiod feminized strains are better suited to growers with some experience. If you’re unsure, get in touch and we’ll help you pick something suitable.

Is the community involvement in naming strains a real thing?

Yes – the Research programme is designed to be more interactive than the standard Sensi catalogue. Growers can provide feedback on new releases and the community has contributed to naming decisions. It’s part of what makes the line feel different from the main brand.

Does Sensi Seeds Research offer CBD strains?

Yes. Skunk Dream CBD is the best-known example – a variety with meaningful CBD content that still carries Sensi’s genetic backbone. A few other balanced varieties are in the range too. Check the current SeedMasters.com listing for up-to-date stock.
