Warlock Feminized Seeds by Serious Seeds
Warlock feminized seeds are an Indica-dominant hybrid from Serious Seeds that delivers a refined cerebral lift balanced by deep physical relaxation — a combination that earned her third place at the 1997 High Times Bio Cannabis Cup and second prize for Solventless Extracts at the 2016 LIFT Expo Cup in Vancouver. She's a genuine 1990s Amsterdam coffee-shop strain that circulated for years before Serious Seeds finally released her as a commercial seed. If you've been growing Dutch genetics for a while, you'll know how rare that pedigree is. If you're newer to it, this is a proper introduction to old-school Amsterdam breeding.
Which Pack Size?
Warlock feminized seeds come in two options. The 6-seed pack (CSSS0017) gives you enough for a solid run with a couple of spares if germination isn't perfect — good starting point if this is your first time with the strain. The 11-seed pack (CSSS0018) is what you want if you're hunting for a standout mother plant or planning multiple grows. More individuals means more phenotypic variation to select from, and you won't need to reorder mid-project.
| Pack | Seeds | Best For |
|---|---|---|
| 6-pack (CSSS0017) | 6 feminized seeds | Single grow cycle, first-time Warlock growers |
| 11-pack (CSSS0018) | 11 feminized seeds | Phenotype hunting, multiple harvests, selecting a mother |
Why Warlock Feminized Seeds Deserve a Spot in Your Garden
Warlock built her reputation the hard way — through word of mouth in Amsterdam coffee shops during the 1990s, long before Instagram grows and seed-bank marketing machines. Serious Seeds developed her from a cross of Skunk and Afghani genetics, and the result is a strain that balances cerebral clarity with full-body Indica weight. The effect isn't a one-dimensional couch-lock; it starts upstairs with a clear, focused lift before the Indica side settles into your limbs. That balance is what kept coffee-shop regulars coming back and what eventually caught the attention of Cannabis Cup judges — twice, nearly twenty years apart.
The resin production on Warlock is exceptional. We're talking a thick, sticky coating across buds and sugar leaves that makes her a strong candidate for solventless extraction — which is exactly what won her that 2016 LIFT Expo Cup prize in Vancouver. If you press rosin or run bubble hash, this is a strain worth growing specifically for that purpose. The trichome coverage is visible to the naked eye from mid-flower onwards.
One honest limitation: Warlock is loud. The aroma during flowering is intense and will require proper odour management if you're growing indoors. A carbon filter isn't optional here — it's a requirement. Plan your ventilation setup before you pop the seeds, not after your neighbours start asking questions.

Growing Warlock Feminized Seeds: What to Expect
Warlock feminized seeds flower in 55-60 days — quick for an Indica-dominant hybrid that produces this much resin. She's not a fussy plant, but she rewards growers who pay attention to a few key details. The Afghani parentage gives her a sturdy, compact structure with thick stems that handle the weight of dense buds without much support. The Skunk side contributes vigour and that unmistakable pungent sweetness that fills a room.
Indoors, expect yields of 14-18 ounces per square metre under proper lighting. Outdoors in a warm, Mediterranean-style climate, individual plants can push up to 18 ounces each. She responds well to SOG and SCROG setups — the compact Indica structure lends itself to an even canopy. Topping early encourages lateral branching and helps maximise light penetration to lower bud sites.
The THC range of 14-22% means you'll see variation between phenotypes. The 11-seed pack gives you the best chance of finding a high-resin, high-THC individual to keep as a mother. If you're growing from the 6-pack, expect solid results across the board — the genetics are stable enough that even the lower end of that range delivers a proper effect.
- Germinate seeds using the paper-towel method or directly in a moist, airy medium like coco or light soil. Warlock feminized seeds typically show taproots within 24-72 hours.
- Transplant seedlings into their final containers once the first set of true leaves appears. 11-litre pots work well for indoor SOG; 20-litre or larger for plants you want to veg longer.
- Veg for 2-4 weeks depending on your space. Warlock stays compact, so she won't stretch excessively — but she does appreciate topping or LST to open up the canopy.
- Flip to 12/12 when plants reach roughly half the final height you want. Expect moderate stretch during the first two weeks of flower.
- Monitor humidity closely from week 3 of flower onwards. Dense Indica buds plus heavy resin equals mould risk if relative humidity creeps above 50%.
- Install a carbon filter and extraction fan before flowering begins. Warlock's aroma is intense — sweet, fruity, and earthy with a sharp pungency that will escape any tent without proper filtration.
- Harvest at 55-60 days of 12/12 when trichomes show mostly milky heads with a few turning amber. The resin coverage will be obvious — a loupe confirms what your eyes already suspect.
Warlock vs. Other Serious Seeds Strains
If you're comparing Warlock feminized seeds to other Serious Seeds genetics, the closest sibling is probably White Russian — another Indica-dominant hybrid with heavy resin production. White Russian tends to hit harder on the physical side with higher average THC, while Warlock offers more cerebral clarity alongside the body relaxation. For growers who want extraction-quality resin with a more balanced effect profile, Warlock is the better pick. If maximum potency is the only goal, White Russian edges ahead.
Compared to AK-47 from the same breeder, Warlock flowers faster (55-60 days versus AK-47's 53-63 days) and produces denser, more compact buds. AK-47 leans more Sativa in its effect, so the choice really comes down to what you want from the finished product. Warlock is the one we'd pick for hash-making and evening use; AK-47 for a more energetic daytime smoke.
Growing Warlock indoors? A carbon filter and extraction fan are non-negotiable for this strain's intense aroma. Pair your seeds with a complete grow tent kit that includes ventilation, or pick up a standalone carbon filter if your setup is already dialled in. For growers planning solventless extraction from Warlock's exceptional resin, a set of bubble hash bags will let you make the most of those trichomes.
