Business Review

Serious Seeds is one of the longest established seed-companies in Holland, concentrating on the production of high-quality, stable and consistent varieties of cannabis seeds.

The production of top quality cannabis-strains for medical and recreational purposes are our highest priority.

Independent and reliable lab tests (over 20 years of experience in this field) have shown that the different Serious Seeds strains produce the strongest plants (highest in THC-content) available on the market today, averaging between 18-22% THC.

These tests were done on plants grown from the same seeds as the customer receives.

For most of our strains, stable plants are crossed to produce the vigorous F1-hybrids that we sell.

You can be assured of good germination and uniform plants, we even guarantee the germination of our seeds.

Serious Seeds are produced in small numbers and are always fresh and hand selected. We test every batch of seeds for germination rate and uniformity of the resulting plants before releasing it.

We are the ONLY company to individually number our packages, so every seed can be followed from production to the point-of-sale in the shop.

Why are there only 18 strains on the Serious’ menu?

First of all, we want to keep quality high and only release a seed strain once it is stable and consistent.

In addition, our company has improved our existing strains through good selections.

When we improve a strain, we sell the improved product with the same name.

Some other companies give these improvements new names and consider them to be “new” strains.

Having sixty kinds that are essentially variations on five themes is not our goal.

Working this way, it takes a long time to produce a new strain which meets our quality standards to rank next to the existing strains of Serious Seeds.

Sorry to all the people who constantly ask for new names, but we are working seriously on new strains, not on making up new names.

As with all of our other products, when we have something “serious”, we will release it.

How can you be sure of the outstanding quality of Serious Seeds?

It is impossible to know anything about the end product by looking at the seed.

The first measure of our quality is the huge number of awards in different cannabis competitions around the world that our fifteen strains have earned since they were created → 85 awards in total until May 2016!!!

The best known cannabis contest is the High Times Cannabis Cup, held annually in Amsterdam and judging dozens of entries. Since 1994 we have received 25 awards from the judges in this event. The press is enthusiastic about our products, as are our thousands of repeat customers.

Secondly, we GUARANTEE the quality of our seeds, if any quality-problems occur we will send you a new FREE package of the strain you bought.

We are the ONLY company to individually number our packages, so every seed can be followed from production to the point-of-sale in the shop.

Why is Serious Seeds your guarantee for success?

All strains developed by Serious Seeds were bred to be stable, homogenous genetics, which are easy to grow for everybody from novice to expert.
