One of Spain’s leading cannabis seeds developers, Big Monster Seeds, are a welcome addition to the ever-growing Marijunaua Grow Shop catalogue.

Launched initially in the early 2010s, Big Monster Seeds were originally inspired by the desire to provide both recreational and medical cannabis consumers with some of Spain and Europe’s most stable marijuana genetics.

Dedicated to the breeding, selection, stabilisation and evolution of the cannabis plant for the creation of superior hybrid strains that are favoured for high commercial performance, Big Monster Seeds are well established in the field of cannabis genetics.

With their limited but exceptional range, Big Monster Seeds ensure that all of their varieties, available in both feminised and autoflowering seeds, have undergone exhaustive, stressful processes to ensure that their strains are genetically accustomed to any potential crop-related issues that may occur in the growing process. 

This definition of vigour in their cannabis genetics is especially prevalent in their range of autoflowering strains, which have been specifically designed to withstand even the harshest growing conditions.

Furthermore, all Big Monster Seeds’ cannabis seeds have been developed by their own Research and Development team, thus ensuring the exclusivity of their parent strains.

Boasting fragrant and varied terpene profiles with typically high cannabinoid levels, including high THCS strains like Big Monster Flow, Big Monster Seeds are responsible for the creation of some of the most potent and genetically stable strains available to grow in Europe today, including Big Monster Auto, Gimli Auto and Green Joint Auto

Offering exceptional durability and potency, Big Monster Seeds are certainly establishing themselves as serial winners in the marijuana seed market today. With several cannabis cup awards, you can be sure that when you choose Big Monster Seeds, you’ll be growing some of the most coveted strains available on the market today. 

Now available at MGS, some of Big Monster Seed’s most popular high THC cannabis strains like Sweet Carrot Jam and Cannape are favoured by both novice growers, experienced cultivators and commercial growers.

Whether you’re looking for potent indica-dominant hybrid cannabis seeds or an uplifting sativa variety, Big Monster Seeds’ award-winning genetics ensure an exciting and rewarding growing experience for both novice and experienced growers alike.

It is great to buy seeds now that it is legal it makes you grow with plants that grow with love and lightPeace to heavens good willMay I Rest In PeacePut the blunt down and pick it up because blunts don’t have legsAnd weed can’t speak unless you make itCuz this is purgatory riightThe bud that doesn’t breathe muchKilling trees that can move is bad luck

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.
