Sirius Black Seeds – Feminized Reliability With Standout Terps
Sirius Black seeds bring flavor, vigor, and straight-up ease to your grow. This Feminized Hybrid cross is bred from Undisclosed (purple-heavy indica lineage rumored), tuned for real-world gardens and consistent runs. It finishes in about 7 to 9 weeks, so you spend less time stressing and more time watching the canopy stack. Plus, authentic genetics backed by Seeds Here Now (est. 2010) means you’re buying confidence, not guesswork. Short story: great terps, steady growth (with an intermediate learning curve).
Sirius Black Seeds – Strain History & Breeding Background
Sirius Black comes from Undisclosed (purple-heavy indica lineage rumored), selected for stable structure, crave-worthy terps, and reliable performance. Bred by Elite Clone Seed Company, it carries the hallmarks of authentic genetics—clean parentage, consistent expression, and strong germination—curated by Seeds Here Now (est. 2010).
Our team lives this stuff—decades of hands-on growing and vendor relationships—so what you get isn’t hype; it’s a vetted cut from a catalog built the hard way.
Sirius Black Seeds – User Reviews
Got real-world results with Sirius Black? Share your notes and photos. Grow logs help the next grower pick with confidence.
What to include: Tent size, light type, medium, nutrients, veg/flower time, dry/cure notes.
What you tasted: Terp profile in plain words—sweet, citrus, earthy, creamy, etc.
What you learned: Any small tweak that made a big difference.
Sirius Black Seeds – Climate & Environment
Sirius Black runs well in most setups. Control is king: steady temps, clean airflow, and proper humidity make the biggest difference.
Best fit: Hybrid plants like moderate temps and good air exchange.
Indoor vs Outdoor: Indoors: easier to lock dialed temps/RH year-round. Outdoors: choose a warm, dry window; avoid long wet spells late in flower.
Targets: Day ~24–26°C, Night ~20–22°C; RH ~60% veg → ~45–50% late flower.
Airflow: Canopy shake test—leaves should gently move. Stale air invites problems.
Sirius Black Seeds – Yield Optimization Tips
Want more from your canopy without headaches? Focus on the basics done right and repeatable.
Start strong: Healthy seedlings, stable VPD, and clean water give you free momentum.
Canopy shape: Even tops catch even light. Train early; keep nodes level.
Nutrient rhythm: Feed to demand. If tips burn, back off. If color fades early, bump N or micros.
Light distance: Follow PPFD, not guesses. Watch leaves—praying is good, canoeing is not.
Finish well: Support heavy branches, keep airflow under the skirt, and dry slow for better bag appeal.
Realistic goal: average yields with quality-first density beat overfed, airy buds every time.
The Sirius Black S1 (Feminized) strain finishes flowering in approximately 7 to 9 weeks, making it a relatively quick hybrid to harvest. This shorter flowering window is ideal for growers who want efficient turnaround times without sacrificing quality. The strain stacks its canopy steadily throughout this period, rewarding patient but attentive cultivators with dense, resinous buds.
The Sirius Black S1 (Feminized) strain produces THC levels ranging from 18% to 24%, delivering a potent hybrid experience suitable for both recreational and therapeutic users. CBD content remains below 1%, meaning this strain leans heavily toward psychoactive effects rather than CBD-dominant relief. The high THC range makes it a strong choice for experienced consumers seeking impactful sessions.
The Sirius Black S1 (Feminized) strain was bred by Elite Clone Seed Company using undisclosed genetics rumored to feature a purple-heavy indica lineage. While the exact parent strains remain proprietary, the indica-dominant influence is evident in the plant's structure and coloring. This S1 (selfed) feminized seed ensures genetic consistency, preserving the standout traits of the original elite clone.
The Sirius Black S1 (Feminized) strain is rated at an intermediate grow difficulty, making it accessible to cultivators with some prior experience. It exhibits steady, vigorous growth throughout its lifecycle and responds well in real-world garden setups. While not the most demanding hybrid, growers should be comfortable managing canopy structure and environmental controls to maximize its standout terpene profile and yield potential.

I just wanted to tell you guys thank you! Got my gear today and I really appreciate that freebie. I was actually looking at that pack so now I can try it first. The stickers are awesome. Your box is amazing. Didn’t know you guys have auctions also I told my dispensary about a year ago to send everyone to you guys. Hopefully they have been because they ask me where people can get seeds and I told them you guys. That was Beyond Hello the goose Lake Road location in Sauget, Illinois. Also, thank you for the pineapple high chew! Love it all! Thank you so much!

Thanks so much, again! I am SOLD
Seedsherenow.com fixed my own boo-boo, and didn't even charge me the difference owned. This is my first plight to cultivate my own potential watching cannabis grow. Packaged included many more things than expected. My call was returned immediately after leaving a short message. I hope to have a plentiful harvest and a great learning experience growing this season. Whatta last minute find watching JB on The Dude Grows Show
