      I was looking for a simple cash crop when i purchased these seeds in April.

      With my purchase i received 3 Victory Red Russian XXL which are vegetating great!!!!!!

      I will try Heavyweight Seeds again, but this time i was unlucky.

    Hello! Thank you for the review.

    We regret to hear that you have faced this issue. We have a claim form for these rare cases of bad germination rate. Please, fill it up and we will proceed with your claim. Kindly remind you that more detailed information increases chances for compensation.


    Although seedbanks guarantee maximum germination, meaning that at least 70% of the seeds in a pack will germinate, seeds remains live biological material. Their germination rate might be affected by a wide range of external factors, such as unsuitable temperature, overwatering or insufficient watering, inconvenient soil content, parasites, fungus and mold, transplants, foliage trimming and many others. We have an article about germination, where you can find the most recommenced and the most popular method of germination.

    We hope that you’ll find this information useful!

      It was a small plant at the beginning but then it turned in to a magic tree. A must have strain.
    • Advantages
      Top quality seeds

      Another great strain from Heavyweight, find this one very skunky though, very smelly even when grown fully organic. But as with all other Heavyweight strains yet to grow one in 56 days. The average I get is 70 days, but the quality and yield is like no other. I am a massive fan of Heavyweight seeds, not for the speed but for their yields, they are without a doubt the highest yields yet from an Auto, and again I find this strain a lot stronger than 18% THC content, this one is definitely well over 20%. My advice is expect to grow them for 70 to 77 days and you will have a great yield with the best quality. This variety is fast and vast for what you get but not in 56 days. But for me quality is more important and heavyweight definitely has that.
    • Advantages
      Easy to Grow, good yield, resistant to abuse ;

      Did these under 600watt HPS in tent using Biobizz soil / nutes. Watch for Mg shortage around week 4 / 5 otherwise spot on. Harvested 77 days from seed and got just under 3oz per plant.
    • Disadvantages
    • General impressions
      Easy to grow, never trained them, just let them do their thing. Nice bit of smoke. Good for stress / sleep and pretty knockout stone, depending how long you let her go.
