Runtz Gum feminized seeds

Smoking Runtz Gum gives you as close an experience to chewing real bubblegum as you can get with a weed strain. Sweet and sour as well as juicy, this citrus-smelling treat is a cross of such West Coast heavyweights as Zkittlez and Grapefruit Bubblegum. The shocking 28% THC in the offspring makes even these distinguished parents proud. The effects are super strong, but balanced in a zen-like way, allowing you to discover hidden sources of creativity in an ocean of perfect bliss.

Runtz Gum Strain Info

With its 60/40 Sativa to Indica ratio, Runtz Gum has the yin and yang of cannabis in perfect equilibrium. This goes both for the way this plant grows and the way its buds act upon the user. The breeders have made certain that, as a grower, you’ll have a perfect experience from seed to incredibly bountiful harvest.


When deciding on the lineage of their next winning hybrid, the breeders obviously had two goals in mind: to create a weed strain that was perfectly delicious, and at the same time filled to the brim with THC-loaded resin. Runtz Gum’s parents, Zkittlez and Grapefruit Bubblegum, are themselves outstanding in both respects – no wonder their cross turned out to be so tasty and potent.


The main feature of the high produced by Runtz Gum is limitless euphoria, which makes your body blissfully relaxed and your mind alert and creative.

THC Levels

Get ready for an unbelievable 28% THC from dried buds. Anything with THC content above 15% would be considered killer weed by most casual users, and here, you have almost twice this amount, meaning that a single hit will make you high for 3-4 hours, with almost no tolerance build-up over weeks or even months.

Smell And Taste

The strong and penetrating aroma of sweet and sour strawberry candy and grapefruit starts when the flowers begin to fill out, and this lavish terpene mix is completely retained in the buds. The smoke is also fruity, and it doesn’t strain your imagination much to think that you’re actually tasting actual bubblegum.


Indoors, Runtz Gum produces harvests that are way above average, with 700g/m2 (2.3oz/ft2) easily achievable. However, it’s in an outdoor garden that these plants truly realize their potential. Though never reaching enormous proportions, they bring in upward of a kilogram (2.2+lb) of buds.

Flowering Time

This hybrid with a slight Sativa dominance finishes flowering in 70 days after the light schedule switch to 12/12. Outdoors, Runtz Gum reaches full maturity in October.

Grow Tips

Offering remarkable hybrid vigor and ease of growth, these seeds are perfect for cultivators of any skill level. Even if this is your first time growing, the process will be hassle-free.

  • Increase indoor yields with topping and training.
  • Be sure to use support for heavy side branches outdoors.

      Being honest she was one of my favourite lady from the Original Sensible Seeds group.... She loves training! And I love her!!!
    • Disadvantages
    • General impressions
      Life is not easy especially when there is a pandemic a corona bug and you can not come back on time to harvest due to flight cancellation....
      But....She was ok 😎 Very ok... This creation is dope.
      I saw from the beggining that she is an aggressive type of plant or let's say gentics or let's say strain. Choose one.
      Grows quick.... There is no problem loves training LST, Fimming, Topping this plant can be tortured hard trust me.....
      Growing level is normal not really big requirements when she is in veg it is normal.
      Flowering yes, she is strechier not crazily but she adds to her size so....
      Flowers are crazy she produced so thick ones.
      Basically I wanna say is that she was not that frosty looking instead thick as fuck but still very very sticky and of course - strong smell.
      Smell is amazing the real strong like e otoc spices.... really nice! I assume she is strong lol....
      Flowering time can take longer without any problem so may be you won't be ready in 8 weeks :)
      I am very satisfied Original Sensible Seeds has done a good job!

    • Advantages
      1 of 3 plants was going to be a very large yielder.
    • Disadvantages
      2 of 3 Runtz Gum plants hermed in DWC. I grew 4 strains and this was the only one to herm. Male flowers up and down the stalks on 2 plants- beyond saving and I'm glad I removed them ASAP when I noticed around week 4. Maybe a dozen seeds resulted in neighboring plants which I discarded.

      These plants were in large stable 120qt bins. Clean roots. The 1 survivor shared a bin with the more vigorous herm so they were subject to identical conditions. The survivor will have a below average yield - I'm avoiding harvest out of disappointment. The other herm was a runt. The only parameter out of spec was lower root temperature of 63f. Powerful LED lights could have contributed though there was no sign of light burn and they had good distance.
    • General impressions
      This was my first grow so some mistakes were made, but the fact remains this was the only strain of 4 to herm. This strain had better and more stable conditions than some others as well so I was very surprised.

      I would grow this brand again since I had great results from their Purple Punch Cookies which was the biggest and strongest of the bunch, but this strain was unstable and stressed me out.

    Hello Pizza Skeleton,

    Thank you for sharing your feedback with us. The plant can become hermaphrodite if it has been stressed during its vegetation state. Stress can be caused by many reasons, such as unsuitable temperature, overwatering or insufficient watering, inconvenient soil content, parasites, fungus and mold, transplants, foliage trimming and many others.

    When the seed germinated it proved its' viability and the further growth depends on the conditions provided. Stability of the strains is guaranteed by the seed banks, but even so it can sometimes go south. The chances for this to happen are relatively small, but it is possible. The problem you are facing most likely could be with particular seeds, not with a strain itself. This strain is reknown for good genetics and unpretentiousness in growing. Hope you'll find your favorite strain of this seed bank and will have the most incredible impressions
    Respectfully, Herbies Seeds
