Choosing Seeds

Feminized seeds flower and grow weed when they receive less than 12 hours of light per day. Harvest outdoors in fall, or indoors after 15-20 weeks. Professional growers use these.

Autoflower seeds grow small, easy-growing plants that you can harvest in 10-14 weeks. Great for new growers, small spaces, and multiple harvests per season!

How To Germinate

Germination is guaranteed when you soak the seeds in water up to 72 hours in darkness. When it shows a tail, put it in loose soil with fertilizer. Keep it light and damp and a seedling will appear!

Runtz Auto Origins

Runtz strain of Cannabis first appeared in 2017 at the Santa Rosa Emerald Cup. Since then, it has won multiple awards, including the 2020 People's choice award for best indica flower. As one would imagine, Runtz Cannabis gets its award-winning genetics from award-winning plants, namely Zkittles and Gelato #33.

The sheer flavor and potency of Runtz Cannabis happened because these two strains were intentionally bred together for their impressive flavor profiles and high THC levels. Gelato #33 won the Leafy strain of the year in 2018, and Zkittlez held the title for best indica flower in 2015's Cannabis Cup.

Cannabis ruderalis, native to Siberia, can also be found within the Runtz autoflower strains' lineage, making it much easier to grow and maintain due to the hardy nature of ruderalis. Ruderalis genes give Runtz the ability to autoflower. You don't need to change the light cycles to initiate flowering. Instead, Runtz auto has a flowering time built into their genetics.

Growing Runtz Autoflower outdoors is a fantastic choice for those with limited summers. It makes it easy to harvest before early frost sets in. It's also great for those with long summers. Thanks to reliable flowering cycles, you can grow up to two autoflowering strains in a single season.

Growing Runtz Autoflower Cannabis Seeds

Our Runtz autoflowering Cannabis seeds are feminized, so you're guaranteed to have only female plants. Female plants, contrary to male plants, are the ones that actually produce weed. Runtz plants are colorful with an almost tropical appearance. The dense buds are compact and covered in trichomes.

Runtz auto seeds grow well indoors, outdoors, or in a greenhouse. Regular marijuana seeds can grow quite large plants, but you can expect smaller ones when growing the autoflowering version. Due to this strain’s dense foliage, pruning is recommended.

With its ruderalis genes, you can expect your plants to grow healthy and hardy with very few finicky tendencies. You can look forward to massive plants with reliable yields with the correct care and attention.

Please read our germination instructions for guaranteed results.

Preferred Climate

Runtz auto seeds grow best in Mediterranean climates and prefer plenty of direct sunlight and warm temperatures. In the right growing conditions, it will thrive outdoors; however, it grows wonderfully indoors as well. Auto flowering seeds will flower on schedule even in less than ideal conditions.

With plenty of water and nutrients, your Runtz plants can grow exceptionally well as they are quite resilient to disease and pests.

Flowering & Yield

Experiencing The Runtz Weed Strain

Runtz produces joyful, euphoric highs with strong cerebral effects that aren't overshadowed by dramatic couch-lock. Its potent brain buzz lasts for hours, surging your creativity and giving you a sense of overall happiness that makes you focused and productive.

That buzz slowly wanes into a tranquil, relaxing body high that eases you into a calm state of bliss. Runtz Cannabis makes it easy to unwind without the brain fog commonly associated with powerful indica strains.

Runtz is flavorful and potent. Those with a low tolerance for THC or new to Cannabis should proceed cautiously. Anxiety or paranoia is common when consumed in excess. It may also cause munchies, thirst, and dry mouth and eyes.

Runtz Smell and Taste

Runtz is named after a candy because it is a sweet treat. The sugary notes have a rich earthiness and just a hint of sourness. However, its fragrance has an unmistakable skunkiness that's impossible to hide. You're welcomed with a fruity zest of berry, grape, and citrus flavors to usher in your buzz from the moment you engage. It's soon followed by a sweet buttery flavor on the exhale with subtle hints of diesel.

Uses for Runtz

Runtz Cannabis typically has a high THC percentage, making it great at elevating moods. However, there is more to this strain than its psychoactive properties. The Runtz strain has many therapeutic uses, perfect for mental and physical ailments.

Runtz Cannabis has various beneficial terpenes such as caryophyllene, humulene, pinene, limonene, and linalool. These terpenes offer both anti-inflammatory and calming properties. When combined with limonene, linalool can lead to feelings of peace and elevated moods of happiness.

Runtz weed can also help with a loss of appetite. Due to its indica qualities, it eases people into a state of comfort and mild sedation, helping those with insomnia.
