Heavyweight Seeds

This Spanish breeding collective is known to produce true knockout strains that will leave your head floating like a butterfly and body buzzing like a bee:

We are, of course, talking about Heavyweight Seeds.

Formed back in 2008, this breeder has built up a strong reputation for producing strains that are highly consistent, stable and of the very finest quality, thanks to their philosophy of only working with the purest, tastiest strains available.

For strains with the best yields and the most potent knockout power, pick Heavyweight Seeds!


Monster Profit Feminised Seeds

Monster Profit Feminized Seeds

The Heavyweight team looked at one another in awe, the smiles said it all. Not only had the scales tipped just over 800gms, the taste was so smooth, so sweet and exotic; nobody was moving. They said it couldn’t be done, but in just over 9 weeks of flowering there it was! A massive central cola surrounded by branches barely able to hold their bountiful buds off the ground, glistening with crystals like a fresh dusting of snow.


Following exhaustive quality tests, Heavyweight are proud to launch the aptly named Monster Profit onto the market. Performing with great distinction under lights or outdoors, this beast cannot be tamed! Simply outstanding results makes Monster Profit the ideal plant for beginners, although commercial growers will undoubtedly want to take advantage of the supreme quality and unrivalled yield this alpha female provides.


Jackpot Auto Seeds

Jackpot Auto Feminised Seeds

Cross Jack Herer with 2 Fast 2 Vast and you’ve won the Auto Jackpot!


This indica-dominant auto-flowering strain is very simple and straightforward to grow, so easy in fact that it belies the sheer quality that this strain produces. With a grow time from germination to harvest of between 60 and 70 days it will mature indoors or outdoors anywhere that the daytime temperature doesn’t fall below 10 degrees such is its hardiness and resilience.


Its height reaches between 80 cm and 100 cm giving it a useful profile for outdoor gardens where tall plants may be a give-away. The buds from this strain literally ooze with THC-carrying resin the buds being much stickier than many autos.


Expect between 50 to 80 gr. per plant. Like its Jack Herer ancestor the initial effect is quite euphoric and energetic but this stage evolves into a particularly deep, relaxing stone that lasts and lasts. The taste begins with the fruitiness of 2 fast 2 Vast before becoming spicy and earthy like Jack Herer. This automatic strain is your winning ticket to happiness.

  5. I run both female and autos. Autos are great because you’re guaranteed a crop . I do however prefer feminised beans cos they are cheaper for me to run plus I always like to have a mother plant. So I’m easy 😉 Thanks for the chance🙏💚🍁🌳💨💨💨

  6. Now I got to get lucky this time. I want those seeds. It would just be the bomb if I won. Lol
    Ty to the Vault for another chance to win some fine genetics.

  7. Wow!!!

    They have some incredible looking buds on their menu — large, dense and frost packed — just the way we love them.

    The Monster Profit, Strawberry Cake, K.O. Kush and especially the Total Paralysis look very, very promising.

    Someone’s going home a Champ on March 12, 2020!!!
