Runtz feminized seeds (Seedstockers)


Runtz Strain Info

Runtz is a feminized cannabis strain brought to you by the breeders at Seeds Stockers. With roots in Gelato 33 and Z – two incredibly powerful and delicious cannabis strains in their own right – Runtz is a pleasure to grow, producing resin-soaked flowers that range in color from lime green to purple. This is a fantastic Indica-dominant variety and a must-try!

Flowering Time

In an indoor grow setup, the flowering time for Runtz is 8-9 weeks, while outdoors, this strain will finish in October.


Runtz is a generous producer, rewarding growers with a good amount of connoisseur-quality buds. Seedstockers doesn’t specify the strain’s indoor or outdoor yields, but those who’ve had the pleasure of growing this beauty claim that indoors, Runtz plants can bring up to 450g/m2 (1.70oz/ft2), which can be increased even further by growing via SoG/SCRoG using high-power lighting. Meanwhile, those who prefer growing outdoors can expect to bring in as much as 500g (1.89oz) per plant! 


This Indica-dominant strain is noted for its smooth and pleasant smoke that brings an incredibly strong and lasting euphoric high, which then phases into a relaxed and happy feeling.


THC Levels

A master of devastating highs, Runtz tests at 25% THC. This impressive level is not the limit – the breeders at Seedstockers claim that this weed strain can be even more potent if grown in optimized conditions. Showing crazy levels of resin, Runtz is also a perfect option for fans of concentrates and extracts.

Smell And Taste

Bred from Gelato 33 and Z, this cannabis strain boasts an even sweeter taste than her parents. Her crazy-tasty terpene profile combines the flavors of ripe fruits and candies with subtle earthy notes. You’ll definitely enjoy her smooth and creamy smoke that welcomes you into a happy and relaxing journey!


Grow Tips

Robust and stable, Runtz adapts well to indoor and outdoor growing conditions and is suitable for novice growers. Plants are taller than you might expect from an Indica-dominant strain, with sizes ranging from 130cm (4’7”) indoors to 180cm (5’11”) outdoors. Here’s some more grow info that will help you further:

  • Outdoor plants appreciate topping and LST techniques.
  • Expect dense and super resinous flowers that are especially great for concentrates.

    • Advantages
      Good stuff!
    • Disadvantages
      Can cause dry mouth
    • General impressions

      Definitely a strain that mellows you, and makes me want to chill and not do much. Very impressed at the flavours in both phenos after just drying and no cure.
      Also no real plant training this run and i got these monsters.
      Had great results, especially when i upgraded to RO water.. if theres one thing i could of changed it would of been using the reverse Osmosis water sooner.
      The rest of the grow was pretty easy, didn't even train my plant. Some good genetics from seedstockers.
