Brand Evolution

Fronting the Fight for Fair Cannabis Policy

Green House Seed Company's owner and operator has always been at the forefront of the fight to normalize marijuana on a global basis, both for recreational and medicinal purposes.

To date, Arjan has opened four successful coffeeshops in Amsterdam, a cannabis social club in Barcelona, two of the world’s biggest seed banks, a specialist weed nutrient company and even a ganja documentary company among other business ventures.

“By making it illegal, politicians ruined everything, like they always do. And, even if it ends up being legal, politicians will find the way to ruin it again, exactly like with tobacco. Do you know how many people die of tobacco? And of alcohol? Politicians do nothing about it. So I repeat: our main issue in the world is our politicians.” - Arjan Roskam

Today, Arjan is considered one of the most important and influential individuals in the commercial cannabis sector worldwide. His company actively encourages pot users to join the fight for legalization and to do their bit to support the cause.

Essential Strains

Catering to the needs of indoor and outdoor growers alike, Green House Seed Company has produced a variety of beans that are suitable for grow spaces of all shapes and sizes. Many of which have become firm favorites among commercial cannabis cultivators and industrial-scale producers, along with amateur home growers worldwide.

Indoors, both White Widow and Great White Shark have earned widespread critical acclaim for their potency, generosity and the simplicity of their cultivation process.

Ideal when working with a relatively confined grow space, neither strain needs a great deal of room to produce plenty of premium pot in next to no time. Strawberry Haze and Neville's Haze are also perfectly suited to indoor grow spaces, though need a little longer to reach maturity.

We'll take a closer look at these standout strains now.


Himalaya Gold

Himalaya Gold is one of its most popular specimens for outdoor cultivation, due to its robust pest resistance and resilience against comparatively cold temperatures.

Ideal for cooler northern climates, Himalayan Gold is notorious for its generous yields and heavy Indica high. Outdoor growers also make a beeline for Arjan's Haze #1, which delivers a quintessentially Sativa buzz and produces huge quantities of cannabis after a flowering time of just 11 weeks.



White Widow

By far one of the most famous strains ever to come from the labs at Green House Seeds, the infamous White Widow is perhaps the ultimate crowd pleaser. First developed almost 30 years ago by combining Brazilian Indica and South Indian Sativa landraces, White Widow is known for her energizing and uplifting high that packs a serious punch.

She was awarded a high-profile prize at the 1995 High Times Cannabis Cup and has been a staple on the scene ever since. THC content tends to come in at around 20%, though can vary from 17% right up to 25%.


Strawberry Haze

Arjan's Strawberry Haze hit the market in 2006, after impressing a panel of cannabis connoisseurs a year earlier. This is a strain that is famed for her succulent strawberry fragrance and fruity flavor profile - both of which are intensified through classic yet careful soil cultivation.

Strawberry Haze typically tests for a THC content in the region of 20%, along with a generous CBD content of around 1.5%. Flowering times come in at around 10 weeks, by which point Strawberry Haze plants will have grown relatively tall with long branches and sparse foliage. An ideal outdoor specimen, if you have the conditions to sustain her.


Neville's Haze

As for Neville's Haze, this is another High Times Cannabis Cup winner from Green House Seeds, with strong Sativa characteristics that deliver a euphoric and giggly high. Potent yet controllable, Neville’s Haze is ideal for firing up those creative juices and giving you the motivation to achieve pretty much anything.

That said, it’s also a potent strain with a THC content in the region of 22%, so it’s fairly easy to get carried away with. Still, take it easy with Neville's Haze and you’re looking at a strain with an endless list of potential recreational and therapeutic applications.
