TH Seeds Seed Bank

01. 03. 2026

Adam and Douge are two friends who founded this seed bank in the capital of the Netherlands - Amsterdam - in 1993. To date, they belong to the oldest and most recognized cannabis seed banks in the world.

In the same year, at the same location, they opened a "Cannabis Information Center" along with the first European cannabis shop called "Hemp Works". This shop is also the birthplace of the "HoodLamb" cannabis clothing brand. For many people, it was a place where they first learned about the extensive use of cannabis. According to Robert C. Clark, author of several books about cannabis, we could simply describe TH Seeds' activities as the "Epicenter of the Cannabis Universe".

Throughout their long history, this bank has won a large number of awards in competitions. Notable formats include High Times Cannabis Cups, Expogrow Cups, and Spannabis. It is also one of the first seed banks to be inducted into the "High Times Seed Bank Hall of Fame". Among TH Seeds fans, we find well-known personalities from around the world. They built their reputation especially on quality strains from the past, such as Original Bubblegum, SAGE ™ and MK-Ultra ™. They are also known for new varieties, notably Strawberry Glue and French Cookies. We must not forget the popular medicinal strains La SAGE ™ CBD and SAGE ™ CBD.

The simple but very apt motto of the TH Seeds seed bank became: "Protect genetics and serve humanity". According to the founders, they are truly excited about the improving public attitude towards medical use and the deepening collaboration between growers, laboratories, experts, and users themselves. The internet is full of positive reviews from satisfied customers. In their offer, we can find feminized, photoperiodic, and autoflowering varieties. Let's take a closer look at some of them.

Bubblegum

The first variety introduced by the TH Seeds seed bank in 1993. It still maintains its place at the top of popularity among users. The strain is stabilized to preserve its most desirable properties, which include fruity aroma and long-lasting taste. If you translate the name of this variety, it will be completely clear why growers chose this name. It is often used for crossbreeding, from which new hybrid models constantly emerge. If you want to start breeding plants, Bubblegum is the right choice. It grows to a height of 120-160 cm, making it suitable for cultivation in spaces with limited room. It is a mixture of indica and sativa, with indica usually predominating. The flowering time is approximately 9 weeks, according to the manufacturer.

French Macaron

This variety was created by crossing Gelato 33 and French Cookies strains. It is characterized by a very interesting taste and appearance. You may have paused over the name "French Macaron". The similarity between the French dessert and this cannabis variety is hidden in its unique taste. Terpenes contained in the chemical profile give the plant a cream and fruit flavor. We mentioned its appearance earlier. During later flowering phases, its leaves turn into striking purple shades that you cannot overlook. It will captivate you with its beauty. It reaches a height of 90-110 cm, again ideal for small spaces. An interesting fact is that despite its small height, French Macaron offers an admirable yield of approximately 600 g/m2. Before harvest time, you'll wait about 9 weeks from planting. Indica dominates here, which we can thank for relaxation and stress reduction. It is sought after for its relaxing effects.

French Cookies

The origin of the variety can be found in California, where growers brought a few seeds that, after some modifications, gave rise to what we now call "French Cookies". During the flowering phase, the plant turns dark purple. In some places, you can notice almost black tones. Combined with glistening resin, it creates an artistic piece that you will admire with every glance. The plant is ready for harvest after approximately 9-10 weeks. It will delight you with a yield of 350-450 g/m2. It grows to a height of 90-130 cm and its aroma and taste resemble ripe grapes. Its use is associated with feelings of complete lightness, muscle tension release, or elevation. It is often sought after in artistic circles for its ability to awaken creativity, which you can thank its genetic predispositions for - 60% sativa, 40% indica.
