Brainstorm (Dutch Passion)

This strain beautifully combines the sturdiness of the famous Northern Lights No.5, with the extreme potency of Haze. These two strains are main cornerstones of the traditional Amsterdam gene pool. Northern Lights is responsible for the high yield, whereas Haze contributes in terms of aroma. This is a well acceptable compromise between yield, taste and potency. Basically a Win-Win-Win situation!

Brainstorm: the result of a heated brainstorming session

Dutch Passion got their crew together for a brainstorming session. Ideas, propositions, and plans were flying across the room. ‘It’s imperative to hybridize the highest yielding strains!’, ‘No, you fool, we need to hybridize the dankest ganja varieties!’, ‘It must be an indica!’, ‘I lost my spliff, where is it!?’... it was a mad house. After hours of heated debates, the dust had settled - Brainstorm was a strain they all could agree on.


This indica-dominant strain runs with the dankest varieties on the market. Dutch Passion mixed the legendary Northern Lights #5 together with 100% Haze genetics. Originally conceived and added to Dutch Passion’s seed collection in 1996, they decided to improve the variety in 2006 by selecting the best performing Brainstorm phenotypes.


Upon consuming Brainstorm, physically stoned effects will emerge. Although, Haze genetics also steadily creep in with positive and uplifting vibes. If one wishes to transport themselves to Amsterdam’s old-school coffeeshops of the 90’s, this cultivar is the desired time machine. The THC levels hit the 12-14%. It’s a relatively mellow and functional strain; one can pursue everyday tasks without constantly entering a room and asking oneself: "Why did I go into this room again...?"


Indoor and outdoor growers will receive an abundance of dank. Serious yields are to be expected, if one treats Brainstorm with love and respect. This cultivar reaches medium heights. After 9 weeks of flowering, Brainstorm is ready for cropping. This hybrid is a sturdy one, novice growers should give it a shot. One must harvest this excellence by October if grown outdoors.
