RS11 Seeds Australia — Rainbow Sherbet #11 Strain Guide
RS11 — Rainbow Sherbet #11 — is the exotic cannabis strain that shifted what the Australian collector market thought tropical terpenes could do. Not the sweetness of a Gelato cross, not the fruit-adjacent brightness of early Z-lineage genetics, but something more...
Permanent Marker Strain Guide — Lineage, Terpenes and What to Hunt For
Permanent Marker cannabis seeds have won back-to-back Strain of the Year awards — High Times 2022 and Leafly 2023. That's not common. Most strains that win one award are quickly eclipsed by whatever the market moves to next. Permanent Marker didn't fade — it held, and...
What Is Phenohunting? The Practice Behind Collector-Grade Cannabis in Australia
Phenohunting is the practice of running a pack of cannabis seeds to find the best individual plant — and then keeping it. Not growing to harvest. Not running seeds for yield. Running seeds to identify the phenotype in the pack worth preserving, running again, and...
THE SIGMA WAY
Modern Genetics. Deep Knowledge.
Exotic Cannabis Seeds Australia
Exotic cannabis seeds is a term the Australian market uses loosely. At Sigma it means something specific — post-2020 genetics chosen for terpene complexity, phenotype variation, and lineage depth. RS11, Future #1, Jealousy. Not the strains that have been in every catalogue for two decades.
The modern exotic cannabis catalogue was built in the US over the last decade — out of the Cookies family, the Z lineage, the OG derivatives that defined the West Coast market. These genetics took years to reach Australian collectors in reliable seed form. Sigma exists to close that gap. The catalogue is built around lines where the terpene profile is genuinely distinctive, the phenotype variation is worth hunting, and the lineage story holds up.
Feminised Cannabis Seeds Australia
Photoperiod genetics — they flower when the light cycle changes, giving the grower full control over vegetative development, structure, and the length of the run. The full range of modern exotic cannabis seeds exists in feminised form. Seed Junky, Archive Seed Bank, Capulator, Anesia Seeds. If terpene complexity, phenotype variation, and running a pack with intention is the goal, feminised cannabis seeds are where serious collectors work.
Cannabis Terpene Profiles — What to Look For
Terpene profile is the most reliable indicator of what a cannabis strain will actually deliver — more reliable than THC percentage, more reliable than indica or sativa classification. The Sigma catalogue is built around strains with distinct, well-documented terpene profiles: myrcene-dominant gas lines, limonene-forward fruit crosses, caryophyllene-heavy OG derivatives. For a full breakdown, see our terpene guide for Australian collectors.
Phenohunting & Collector Genetics Australia
Phenohunting is the practice of running a pack of cannabis seeds to find the best individual plant — and keeping it. It’s the practice at the heart of collector-grade cannabis culture and the reason pack variation matters. The genetics in the Sigma catalogue are selected specifically because they throw variation worth hunting. See our phenohunting guide for the full framework.
Frequently Asked Questions
Why don’t you carry more strains?
Our philosophy is curation over volume. Rather than stocking hundreds of generic strains, we hand-select lines that stand apart for their rarity, heritage, or breeder craft. Sigma exists for connoisseurs who value the right strains, not all strains.
What types of genetics does Sigma focus on?
Sigma Seeds focuses on modern exotic cannabis genetics inspired by contemporary breeding culture — including terpene-rich hybrids, rare crosses, and carefully selected cultivars known for resin production, flavour, and phenotype variation.
Why are your seeds more expensive than others?
Our prices reflect the limited nature of the batches, the cost of germination testing and grow-outs, and the effort required to source genetics worth carrying. Sigma is not for everyone — it’s for collectors who understand that good genetics aren’t cheap, and cheap genetics aren’t good.
Are your seeds germination tested?
Yes. All Sigma Seeds stock is germination tested before release to ensure healthy viability and strong early growth performance. If you experience genuine germination issues using our recommended method, contact us and we’ll make it right.
