Oakland, California, UNITED STATES
OAKLAND, Calif. and HALF MOON BAY, Calif., Jan. 31, 2022 (GLOBE NEWSWIRE) — Dark Heart Industries, California’s leading cannabis genetics company, today announced the world’s first seedless triploid cannabis for commercial growers. Dark Heart’s PistilGuard technology produces triploid cannabis seeds and clones that essentially cannot produce seed, even when directly exposed to pollen. This technology innovation means that triploid cannabis can be grown on the same scale as corn, wheat, or industrial hemp.
“Our cannabis genetics using PistilGuard triploid technology are an industry first,” said Dan Grace, founder and CEO of Dark Heart Industries and Dark Heart Nursery. “The ability to grow THC-rich cannabis from sterile, triploid seeds and clones that are guaranteed to produce virtually seedless plants is a huge win for the cultivators we support. Pollen-proof cannabis, and the advantages it offers, will help move cannabis production from artisanal cultivation to large-scale agriculture.”
“The development of triploid seedless varieties has been a huge step forward in many commercial crops including watermelon, banana, and apples,” said Ken Owens, PhD vegetable breeder and former President of Magnum Seeds. “This trait’s introduction in cannabis is a real breakthrough that will allow higher yields, reduced costs as well as improved aromatic and chemical qualities of the crop. All this leads to higher profitability and control of your crop.”
“Now that scientists at Dark Heart have developed the core technology, they’ll be able to introduce new seedless, triploid-based strains and cultivars through traditional breeding that should bring cannabis production to a whole new level very soon,” added Owens.
Cannabis Genetics 1970s – 2022
The presence of seeds in cannabis plants decreases the density of cannabinoids and terpenes, leading to low THC production, loss of yield and diminished bag appeal. So breeders have long sought ways to remove seeds from cannabis.
In the 1970’s, cannabis farmers produced the first breakthrough in the campaign to produce seedless cannabis when they introduced Cannabis Sinsemilla—in Spanish “without seeds”—by physically isolating female plants from the presence of any pollen-producing males.
Further advances were made in the 1990’s with the introduction of feminized cannabis seed, capable of producing overwhelmingly female plants. However even plants grown from feminized seed were still susceptible to accidental pollination from within the greenhouse or from neighboring fields in outdoor grows. Feminized seed can also still produce phenotypically male plants, albeit in very small amounts.
Producing seedless cannabis plants effectively solves this problem. Triploid seed-based plants are practically incapable of setting seed–even when directly exposed to male pollen. Male plants in the same field, same greenhouse or neighboring field are not a problem for a triploid crop.
PistilGuard branded seeds and clones will be available exclusively to Dark Heart customers and partners this year through field trials, then will be generally available for sale to all California commercial growers in 2023.

Best Marijuana Seeds Banks – FAQs
How Can I Buy Marijuana Seeds Online Safely in the US?
If you use one of the best seed banks like ILGM or Seedsman, then your weed seeds get to you in the USA safely with stealth shipping.
Stealth shipping refers to when seeds are packed and concealed in or around random objects like pens, toys, CD cases, and more to avoid unnecessary attention from customs officers or reduce the chance of theft.
Additionally, most seed banks allow you to buy cannabis seeds with Bitcoin. This is perhaps one of the most secure payment methods to keep your financial and personal information private.
With a combination of the best seed banks, stealth shipping, and Bitcoin payments, you can significantly reduce the likelihood that you will be caught shipping weed seeds to the US.
What Seed Banks Ship to the USA?
Seed banks that ship to the USA include ILGM, Seedsman, and Crop King Seeds.
However, ILGM and Crop King Seeds tend to have faster and more affordable US delivery times. Usually, you’ll have your marijuana seeds at your doorstep within a week of ordering.
On top of that, all orders are coupled with a germination guarantee cover and a good chance at getting 10 extra marijuana seeds with your purchases.
Is ILGM a Good Seed Bank?
Yes, I Love Growing Marijuana is a good seed bank and this is because it is suitable for both experienced and new growers.
The seed bank boasts a decent high-quality range of seeds and strains, as well as 200+ informative blogs and articles and even a forum to help growers make informed cannabis seed decisions in the future.
Furthermore, you get 24/7 growth support assistance at your disposal whenever you encounter a problem.
How Can You Tell if a Seed Is Male or Female?
It is almost practically impossible to tell a female or a male marijuana seed just by sight alone. You can tell the sex of a seed by using a lab test or using a plant sex kit to test for the Y chromosome. But as seeds start pre-flowering their visible differences begin to appear. And here are two tips you can use to sex cannabis seeds;
- Male seeds grow a pollen sack at the branch joints when pre-flowering
- Male marijuana seeds generally grow much faster
- Female plants grow light whitish pistillates
- Female seeds take longer to grow on average
What’s Better – Autoflower or Feminized Seeds?
The better seed between autoflower and feminized seeds depends on the preference of the grower.
Generally, autoflower marijuana seeds can grow with little to no supervision, making them ideal for new growers.
They also grow faster – as fast as 8-10 weeks from germination to maturity. However, they usually have a lower THC potency.
In other words, you won’t get as high from their buds.
On the other hand, Feminized Seeds (if taken care of well) will guarantee high THC or CBD buds during harvest.
However, they take a few weeks longer to mature and will need some higher level of expertise in marijuana growing since they are prone to diseases.
Conclusion – What Are the Best Seed Banks in 2021?
Different seed banks have different strengths, and you can see these from the seed bank features.
However, ILGM (I Love Growing Marijuana) seems to have the best-balanced features of all seed banks, like a good selection of beginner and advanced grower marijuana seeds, educational guides, the highest germination guarantee, and 24/7 support for growers.
But still, Seedsman and Crop King Seeds are other go-to options to buy marijuana seeds online if you wish for variety and fast discreet shipping to your doorstep.
Pro Tip: To ensure most if not all of your marijuana seeds germinate, use the germination guides from the respective sites for the highest germination rates.
