Greenhouse Seed Reputation – 5/5

Strain Hunters TV series

Many factors make Greenhouse Seeds a reputable company, and perhaps the very first one is that they cultivate all their products without the use of any genetic modification or fungicides.

Roskam, the owner of the company has made quite a few television appearances to talk about his approach to marijuana cultivation as well. A series of documentaries made in 2008 is called “Strain Hunters“, and it basically shows how he and his team travel the world to track down the best weed strains and make them available to the general public via his company Greenhouse Seeds.

Seed Selection – 5/5

Some of the most popular strains include Train wreck, Green O-Matic, Exodus cheese, Greenhouse skunk as well as Himalaya gold.

Product Quality – 5/5

Greenhouse Seed in Jamaica

Product quality is probably one of the Greenhouse Seeds highest Highest priorities.

Their commitment to quality sourcing is evidence of this and the fact that they have searched the world over in order to provide the best quality strains and seeds to their customers shows their level of dedication as well.

The company has also won 40 different cannabis cups and 17 highlife cups to date, which in itself is evidence of the high-quality seeds and strains that this company invests in.

Customer service – 3/5

Customer Service BC Seeds Review

Greenhouse Seeds has a stellar rating as one of the best seed banks in the world. However, when it comes to their customer service department, it is somewhat lacking.

Although they offer an excellent range of products, customers have reported that they are a bit laid-back when it comes to resolving issues that are raised, especially issues with the germination of the seeds.

Their products are high quality, however, should a customer experience an issue it is expected that the least a company can do is resolve to assist the client in every way possible and come to a resolution as soon as possible.

So if there is any department or category that Greenhouse Seeds can brush up on, it definitely is their delivery of customer support.

Shipping Methods and Return Policy – 4/5

Shipping Growers MSNL Seeds Review

If you reside in the United States, then, unfortunately, you have to wait a while before getting to experience Greenhouse Seeds quality seeds.

Due to the political situation, the company does not ship marijuana seeds to the US at this point and time.

The company does have some pretty polished looking stealth shipping methods that work most of the time.

Within the Netherlands or locally, the company sends packages out normally with signed delivery.

The delivery time is neither fast nor slow and can be compared to being in line with other major brands.

In the event that you would like to exchange or return a product and it falls under the Greenhouse Seeds terms and conditions on their site, all you need to do is download the return form, complete it and email it to their support department and they will issue you with further instructions.

Payment Options – 4/5

Money Transfer

When it comes to payment options, customers have a choice of bank transfer, cash in an envelope and payment via Cryptocurrency.

Alternatively, when you go to the payment method screen, you will also find a “contact us for details” button, and no one really knows for sure exactly what payment method option that button entails.

However it is good to know that they are flexible. Some customers, however, are disappointed that they don’t accept credit cards. FAQ

What are the best seeds for the growing beginners? 

If it’s your first time attempting to grow a marijuana garden, then you’ve still got a long way to go. There are lots to learn when it comes to growing the different types of seeds, and if it’s your first time, you need to know which seeds are easier to grow. 

Auto-flowering seeds are the preferred choice for beginners since you don’t need to focus much time and energy on the light and dark schedule as they are auto-flowering. They also tend to be more forgiving of any mistakes that you are prone to make as a beginner. 

Exodus Cheese Auto

Exodus Cheese Auto introduces Ruderalis genes to the superior Exodus cheese strain from the United Kingdom.

However it does remain true to the original in terms of its taste and effect. It consists of 50% Indica, 30 % Sativa, and 20% Ruderalis. The lifecycle from germination through to harvest is 9 to 11 weeks, and it yields 500 g/M2.

Outdoor growing will see a small plant that won’t grow higher than 90 cm and will yield between 70 to 80 g per plant. Multiple harvests are possible with this strain provided that temperatures stay above 10°C, so for warmer regions, this is more easily achieved. 

It also has a classic musky, earthy flavor with notes of actual hard cheese, and it ultimately delivers a solid stone.


The Green O-Matic is an autoflowering cannabis strain created from Lowryder with the addition of white dwarf and Moroccan genetics. The plant will be ready to harvest approximately 55 to 60 days from germination.

It contains 80% Indica, 10% Sativa than 10% Ruderalis. The yields are as much as 800 g/m2 with an indoor setup. If you choose to grow it outdoors it will remain short at approximately 30 to 40 cm and yield about 30 g per plant.

One of the advantages of the strain is that as long as there is sufficient daylight and the temperature remains constant at 10°C, it can be flowered and matured at any time of the year. 

This also makes it ideal for beginners and those who want yields all year round. THC production is impressive at 15.43%, along with an average CBD content of 0.09%. The effect is a fast-acting, and long-lasting stoned feeling. 

Northern Lights Auto

Northern lights is a product of Greenhouse Seeds that was created by crossing Northern lights with the Green-O-Matic auto-flowering strain. The plant is 80% Indica, 10% Sativa, and 10% Ruderalis. From germination to harvest, it will take approximately 10 weeks.

The seed starts to flower in the 3rd week of growth, and indoor yields will give you 800 g/m2. Outdoor yields will have you seeing approximately 100 to 150 g per plant. The plant itself is medium-sized and will grow between 90 to 120 cm in height. 

It is possible to get more than one consecutive harvest per growing season as long as temperatures don’t go below 10°C. The flavor and the aroma of this plant are very distinctive and usually compared to incense and hashish. It’s fast-acting and well-balanced so it can be used day or night.

White Widow Auto

White widow auto is the auto-flowering version of this popular strain. Like it’s photoperiod counterpart, it is the combination of a careful selection that produces a short and more compact plant with vigorous growth as well as dense and resinous buds. It is, therefore, easy to grow and the perfect strain for newbies. It is a strain grown from Brazilian landrace Sativa and a South Indian Indica with Ruderalis genetics.

The seed grows well irrespective of whether you choose to keep it indoors or outdoors. The complete lifecycle is between 70 to 80 days from seed growing to a height of 70-100 cm. The yields are between 450 to 500g/m2.

When grown outdoors, you will receive decent yields, and the plant grows up to 100-140 cm when grown in the ground.

The flavor is an earthy, woody, and floral note. THC levels are high at up to 16%, and it delivers a nice balanced effect, which is relaxing.
