Former biology teacher and long time cannabis grower Simon used to work for Sensi Seeds until his creations ‘AK-47’ and ‘Chronic’ both won prices at the High Times Cannabis Cup in Amsterdam, back in 1994. A year later, Simon decided it was time to start his own seed bank.

A serious step towards a serious career change, no wonder he named his company ‘Serious Seeds’. 

Now, years later and up until 2017, Serious Seeds’ strains have won over 90 different international awards. Some of these award-winning strains you might know as; AK-47, Bubble Gum, Chronic, Kali Mist, White Russian, Double Dutch and Biddy Early,

We offer cannabis seeds by Serious Seeds in regular form as well as feminized, autoflower and CBD-rich versions.

I placed 1 order on the 21st and another order on the 30th of November because of the incredible sale they were running and both of my orders arrived before Christmas. I was very impressed that they both delivered in timely manner. With the vast selection and a good price, I will be doing business with them again. Great job MGS.
