Sensi Seeds

Today, Sensi Seeds is one of the most renowned cannabis seed banks on the planet. Although it all started with one man’s passion for cannabis, the company has grown into a legendary titan over the decades, getting involved in every aspect of the cannabis community. Now they have branches that reach far beyond cannabis breeding, with various aspects of the company specifically dedicated to the advancement of industrial hemp, as well as another dedicated to educating the public on the many benefits cannabis has to offer society – helping dispel the myths perpetuated by the War on Drugs.

Sensi Seeds is more than just a seed company; it is a part of the lifeblood of the cannabis movement. Everything Sensi does is done by putting the plant first.

The History of Sensi Seeds

With this in mind, here is a rundown of Sensi Seed’s history, giving you a glimpse into the core values of this seed bank – one of the first to offer cannabis seeds to the general public.

Sensi Seeds’ story all comes back to Ben Dronkers, the founder of Sensi Seeds. It was back in the 70’s when Dronkers first got into growing cannabis that the insatiable appetite for knowledge took hold. Not only did he start collecting seeds, but he also worked closely with botanists, researchers and even farmers to grasp a better understanding of the plant. Over time, Dronkers concluded that, irrespective of growing skill or care, the core genetic quality of a strain dictated its potential for growth.

With this knowledge firmly in hand, he set about exploring the world, collecting cannabis from across the globe; cataloguing and documenting the particularly impressive examples he found. Everywhere with a rich history of cannabis cultivation, Dronkers visited, and the collection of top-class sativa and indica seeds he brought back home with him in the 80’s would be the foundation of Sensi Seeds’ breeding program. With these, he began to experiment, crossing the various strains he had collected and working to stabilise them into all new varieties of cannabis.

It was around this time that the first wave of US hybrid strains hit the scene, such as Skunk and Haze - and Dronkers was one of three Dutch breeders to get his hands on them. This only skyrocketed his knowledge of breeding and allowed him to further bolster and strengthen his breeding program with all new genetics.

In 1985, Dronkers took his creations and founded the Sensi Seed Club – a club for connoisseurs, and the first iteration of Sensi Seeds. With this, his “hobby” breeding took on another level, and the club worked to centralise their growing, as well as standardise the entire process involved. It led to a need for a newer, bigger area to work with – which is when Dronkers went official, obtaining the facilities required to grow, monitor and document his various cannabis strains with scientific precision. It was the true beginning of the Sensi Seeds we know today.

Of course, the story for Sensi Seeds did not end in the 80’s. It was in 1986 that they first opened up the Sensi Seed Club shop in Amsterdam, supplying their genetics and those from The Seed Bank - a company founded by another Dutch breeder who received the first US hybrid genetics. In 1991, Dronkers bought The Seed Bank, combining the companies and expanding their genetic library even further.

Since then, Sensi Seeds have continued to hunt down world-class genetics and use them to innovate. Such results include Mother’s Finest, Big Bud, Skunk #1, and Master Kush – all renowned favourites among connoisseurs, veterans and novices alike. In 2006, Dronkers was also offered the opportunity to buy the Flying Dutchman seed bank, another of the Dutch originals. This further augmented the Sensi genetic pool and ensured that the Flying Dutchman legacy was maintained.

Today, Sensi Seeds sit in the halls of fame as one of the most responsible, knowledgeable and reputable seed banks there is. They continue to push cannabis breeding to its limits and consistently amaze with the strains they produce. As you can imagine, they have quite a few Cannabis Cups under their belt.

Where Is Sensi Seeds Located?

Originally carving out a name for themselves in Amsterdam, Sensi Seeds has three stores you can visit to pick up your seeds. Not content with confining themselves to the Netherlands, if you find yourself in Spain, you can even visit their store located in the Gothic Quarter of Barcelona. Of course, if you want to save yourself the airfare and travel expenses, you can always visit the Zamnesia online store to pick up your favourite strains. Delivered straight to your door, we’re only a click away!

Packaging Sensi Seeds

Sensi Seeds supply all their cannabis seeds with two layers of protection, ensuring safety and quality every time.

Firstly, seeds are housed in a plastic forward surround for added durability. This plastic is attached to the strain card, which details everything you need to know about it, including its general characteristics such as average height, yields and growing time. On the back of the packet, there is a small perforated section of cardboard, giving easy access to the plastic pod the seeds are housed in.

To add extra protection to the seeds, Sensi Seeds take all of the above and then place it in a sealed Sensi Seeds box, ensuring they get to you safe and securely. 

Please note, the Sensi Seeds packaging is not resealable once opened. If you do not intend to use all seeds at the same time, ensure that you have suitable seed storage lined up.

What Is the Difference Between Feminized, Autoflowering, and Regular Seeds?

This is a common question amongst those looking to take their first steps into the world of home growing. Even experienced hands can use a little reminder on the differences between feminized, regular, and autoflowering seeds to help make the most informed purchase possible.

Luckily, Sensi Seeds has a great colour coding system for their seed packets, so you can't go wrong. Regular seeds are indicated by green packaging, feminized seeds are in purple packets, and autoflowering seeds can be found in either grey or blue bags, depending on the seeds.

• Regular seeds, such as Jamaican Pearl and Mexican Sativa, have a 50% chance of becoming male or female.

• Feminized seeds, such as Cobalt Haze and Northern Lights, are created to ensure a near 100% chance of growing female plants.

• While all cannabis plants need maintenance during their life cycle, autoflowering seeds, such as Blue Bullet Auto and Afghani 1 Auto, flower independently of the light cycle. They naturally move from veg to bloom after about 3–4 weeks of growing.

Are Sensi Seeds Any Good?

Since their inception in 1985, Sensi Seeds has well and truly been at the forefront of seed bank innovation. While some seed banks can get a little complacent, Sensi Seeds is quite the opposite, continuing to produce the best strains around year after year.

They have pioneered and perfected such strains as Northern Lights, Big Bud, and Skunk #1, which have not only received acclaim from cannabis consumers, but critics as well. Sensi Seeds is a true champion, having won more Cannabis Cups than any other seed bank in history. They have also been featured numerous times in Zamnesia blog posts. So, we guess you could say you're in the hands of a seed bank that truly knows quality, and how to deliver it.

How Do You Germinate Sensi Seeds?

While there are many ways to germinate seeds, and everyone you speak to will have their own “tried and tested” methods, it ultimately comes down to personal preference and circumstances. However, there are two reliable ways you can give your plants the best start in their growing cycle.

Germinating Cannabis Seeds Directly in the Medium

If you've already got your chosen plant pot and medium, why complicate things by moving seeds to a different environment? Simply plant your Sensi seeds directly into the soil. Place the seed about 0.5cm deep into the soil, cover lightly, and keep your growing area at a warm and humid 20°C.

Germinating Cannabis Seeds With Germination Kits

Germination kits, such as Zamnesia Smart Start and the Plagron Seedbox, offer a great, reliable way to kick-start your plant’s life. Germination kits come with small individual pots that allow you to germinate numerous seeds at once—each pot containing the perfect level of soil. Once populated with your Sensi seeds, the germination kit will need to be kept in a suitable location at room temperature. The use of a propagator will give you the best environment for your seeds to develop.
