About MSB
The first seed bank For breeders By breeders

Welcome to marijuana seed breeders.com!

The first seed bank for breeders by breeders.

We aim to develop quality cannabis seeds in a sustainable way at affordable prices.

Whether you are just taking your first steps on the path of cannabis cultivation or already have years of experience under your belt: if you order your cannabis seeds online at Marijuana Seed Breeders, this could be the beginning of a beautiful collaboration!

How it all started

Creator and Bob had been working together for quite a while when Creator met old warhorse Henk through a Grow forum. They had an instant connection and could spend hours and hours talking about crossings, phenotypes, and our hopes and dreams of creating new and innovative strains.

Once the three of us met in person to try out each other’s creations, all the pieces fell into place. How awesome would it be to set something up with our combined expertise and knowledge?

With the help of a computer-savvy relative, we finally took the plunge and decided to make our dream come true and start our own seed bank online, where we would sell only marijuana seeds of the highest quality.

Together we have over 30 years of experience and all worked with multiple other seed banks in the past. Dedicated to our craft, we couldn't stand the fact that our precious seeds were sold while mixed with lower quality bulk seeds. As well as the generally lax attitude concerning dealings with customers. And so, the idea for their own shop arose.

At Marijuana Seed Breeders we think that quality is the most important thing we can offer our customers. Quality seeds make sure we keep you happy and high. The breeder’s selection of Marijuana Seed Breeders.com contains the best quality marijuana seeds we have to offer.

A dream come true

Our marijuana seed bank opened its virtual doors in 2019. Founded by 3 passionate breeders that shared a common dream: To offer the best weed seeds and share their knowledge and experience with the world.

What sets us apart from the rest is that we strongly feel that offering premium cannabis seeds and excellent customer care should go hand in hand. Yes, we would like to be profitable like any other business of course. However, dollar bills are absolutely not our sole priority. We, therefore, maintain fair prices that are proportional to the time and effort we put into it.

We love keeping in touch with our customers and are always excited to answer questions and to offer our guidance wherever we can.

The idea is to create a strong community of kindred spirits with one common denominator: The love for that miraculous plant we call marijuana.

How do we select the best seeds?

Bulk cannabis seeds from MSB

There are more than a few things that are important while selecting the best seeds for our customers. For instance, we look at how quickly a seed can grow into a plant and how quickly it can root. We also look at other factors like internode distance, stress sensitivity, color, odor, length, the construction of the buds, flowering time, and yield. The ground rule is to select the best phenotypes from at least a hundred plants of one regular species. These selected plants are used to create new strains.

The best seeds because of research

Over the years we’ve made more than 200 selections, which resulted in about 40 different strains. We work on new strains daily with a great deal of enthusiasm. Our goal is to create strains for all growers. Easy to grow strains for beginning growers, but also strains that require a lot of love and attention from experienced breeders.

We try to listen as well as possible to meet the wishes of our customers, especially when they are experiencing sickness or pain.

And, in the last ten years, we have been doing extensive research. This way we were able to select and breed the best seeds. Two things that are very important for us are the continuous quality and freshness of our breeders’ selection of marijuana seeds. We all grow our seeds on soil with mycorrhiza and organic fertilizers.

Seeds for every setup

Whether you have a large meadow or a small cupboard closet at your disposal, Marijuana Seed Breeders has the perfect cannabis seeds for you.

Do you want to grow all year round? Growing seeds in an environment where you have full control over all the factors for which you normally depend on the weather be an exciting endeavor. The indoor seeds selection from Marijuana Seed Breeders designed especially for indoor cultivation.

The beauty of outdoor growing is that everything you need is right there! Our outdoor seeds can grow in any type of soil and all you have to do is make sure they receive a good deal of sunlight and water.

We have a lot of cannabis seeds varieties to choose from. Are you interested in Sativa seeds or rather Indica seeds? Or why not go for the best of both worlds with our hybrid seeds?

Would you like to grow feminized marijuana seeds or isn’t that really that important to you?

We offer a selection of premium weed seeds for every occasion just waiting to discover.

Get your seed directly from the weed capital of the world

There is no better place to get your marijuana seeds from than Amsterdam. Amsterdam after all remains the weed capital of the world. (Yes, you spotted some proud patriotism there indeed ;-) Your seeds won’t lay in a storage room for months: you will get them straight from our grow spaces after we carefully inspected them of course. Because we decided to team up you will have more options taste-wise as well as benefit from all our combined expertise and knowledge.

We are extremely happy to present the result of our alliance: MarijanaSeedBreeders.com. We couldn't be prouder to work with such like-minded people and share our love of marijuana with the world.
