Trusted by Australian collectors.
What an absolute pleasure to find an Aussie seed bank with world-class genetics. Didn't think it would ever happen. Never had a problem with delivery, quality or germination.
Everything arrived as described in a very timely manner, and it was a 5 out of 5 success rate. Very pleased. Will purchase a different strain soon.
Juicy, hard, fat colas, full dark purple against bright vibrant green. Resin-filled, a massive 14oz dry. Great genetics.
Amazed to see this strain available in Australia, and delighted to report the genetics are robust and lively. Perhaps the most vigorous of all my seedlings this year.
100% reliable and quality. Great after-sales service. I don't buy anywhere else.
These are absolute fire. Easy grow, and potent, beautiful flowers.
Frequently Asked Questions
What makes Sigma Seeds different?
We have one founder based in the US, another in Europe and another in Australia. We all have years of experience in the industry. This gives us a unique perspective.
We have decided to focus on modern exotic cannabis genetics — small-batch selections chosen for terpene profile, lineage, structure, and phenotype variation. We prioritise carefully sourced, line-worked genetics inspired by contemporary European and US breeding culture.
How long does shipping take?
Orders are shipped from within Australia and typically arrive within 3–7 business days depending on your location. Rural addresses can take a little bit longer. All orders include full tracking so you can follow your parcel at every step.
Are your seeds germination tested?
Yes. All Sigma Seeds stock is germination tested before release. We only release seeds that meet our internal quality standards for viability, stability, and healthy early growth performance.
What if my order is lost in transit?
We guarantee your delivery. If a parcel is confirmed as lost in transit we’ll resend it. Simple as that.
What's the legal status of buying cannabis seeds in Australia?
Cannabis seeds are sold by Sigma as collectable souvenirs only. Laws regarding cannabis cultivation vary by state and territory — it is your responsibility to understand the laws applicable in your location.
What types of genetics does Sigma Seeds focus on?
Sigma Seeds focuses on modern exotic cannabis genetics inspired by contemporary US breeding culture — including terpene-rich hybrids, rare crosses, and carefully selected modern cultivars chosen for structure, resin production, and phenotype variation.
