La Blanca Feminised Cannabis Seeds by Kannabia
La Blanca is a feminised cannabis seed from Kannabia that packs the genetics of three legendary white strains into one heavy-yielding, resin-drenched plant. Born from the cross of Great White Shark and Snow White, then backcrossed with White Widow, this is triple-white lineage distilled into a single, fast-flowering seed. If you want dense, frosty nugs without fussing over a temperamental plant, La Blanca is where you start.
Why La Blanca Cannabis Seeds Deserve a Spot in Your Grow
La Blanca feminised seeds carry genetics from three of the most respected "white" strains in cannabis history. Kannabia crossed Great White Shark with Snow White, then ran that hybrid back into White Widow — stacking resin production, vigour, and that unmistakable skunky nose that the white family is known for. The result is a plant that produces high THC and CBD levels and finishes flowering in roughly 8 weeks.
What we'd highlight: she's properly forgiving. Mould resistance is strong, she handles colder conditions without sulking, and she grows well both indoors and outdoors. Outdoors she can stretch up to 3 metres tall — a proper tree if you let her run. Indoors, she responds brilliantly to a ScrOG setup, spreading her canopy out to catch every photon you throw at her. In good conditions, you're looking at up to 500 grams per plant. That's not a typo.
The one honest limitation: because she can stretch tall outdoors, you'll want to plan your space. If you're growing on a balcony or in a small garden, some low-stress training early on will keep her manageable. Indoors with a ScrOG net, this isn't an issue at all.

How La Blanca Compares to Other White Family Strains
La Blanca feminised seeds sit in a crowded family, so here's how she stacks up against two other popular white-lineage options you'll find in our catalogue.
| Trait | La Blanca (Kannabia) | White Widow (classic) | Great White Shark |
|---|---|---|---|
| Flowering Time | ~8 weeks | ~8-9 weeks | ~9 weeks |
| Yield Potential | Up to 500g/plant | ~350-400g/plant | ~400-450g/plant |
| Mould Resistance | Strong | Moderate | Moderate-Good |
| Outdoor Height | Up to 3m | Up to 2m | Up to 2.5m |
| Grow Difficulty | Easy | Easy-Moderate | Moderate |
| CBD Presence | Notable | Low | Moderate |
La Blanca edges ahead on yield and resilience. If you're after the classic White Widow flavour profile but want more forgiving genetics and heavier harvests, this is the upgrade. We'd pick La Blanca over a standard White Widow for outdoor grows in northern European climates — that mould resistance and cold tolerance make a real difference when September gets damp.
How to Grow La Blanca Feminised Seeds
- Germinate your La Blanca seeds using the paper towel method or directly in a starter plug. Keep the environment warm (22-25°C) and moist. Taproots typically emerge within 24-72 hours.
- Transplant seedlings into their final containers once they've developed 2-3 sets of true leaves. For indoor ScrOG setups, 11-15 litre pots work well. Outdoors, go bigger — 25 litres or directly in the ground.
- During vegetative growth, maintain 18 hours of light indoors. Outdoors, plant after the last frost. La Blanca responds well to topping and low-stress training to increase bud sites.
- Switch to a 12/12 light cycle indoors to trigger flowering. The flowering period runs approximately 8 weeks. Watch for the canopy to fill with dense, resin-heavy buds.
- In the final 2 weeks, monitor trichome colour with a jeweller's loupe. Harvest when trichomes shift from clear to mostly milky with a few amber — this is where the balanced physical and mental effect is at its peak.
- Dry in a dark, ventilated space at 18-20°C and 55-60% humidity for 7-10 days. Cure in glass jars for at least 2 weeks, burping daily. The skunky, white-family aroma deepens significantly with a proper cure.
What La Blanca Smells and Smokes Like
The nose on La Blanca is unmistakably skunky — that pungent, sharp funk the white family is known for, with a slightly sweet, earthy undertone that rounds it out. During flowering, your grow space will smell like it. A carbon filter isn't optional if discretion matters.
The dried and cured flower produces big, resin-covered nugs that are dense to the touch and slightly sticky even after a proper cure. When broken apart, the trichome coverage is visible to the naked eye — a sign of the high cannabinoid production this lineage is bred for. The smoke is described as delivering a strong, balanced physical stone paired with a pleasant mental component. Both THC and CBD levels are elevated in this strain, which contributes to that balanced character.
Complete your La Blanca setup with a ScrOG net to maximise indoor yields — she's built for it. If you're growing outdoors, pair these seeds with a quality pH meter and organic soil amendments to get the most from her generous genetics. For drying and curing, glass jars with humidity packs keep your harvest in peak condition.
Who Should Grow La Blanca
La Blanca feminised seeds are the best white-family strain for growers who want reliability without sacrificing potency or yield. If you've grown a White Widow before and want to step up to something that produces more, finishes in the same timeframe, and shrugs off mould — this is it.
She's also a solid pick for outdoor growers in cooler climates. That cold tolerance and mould resistance aren't just marketing lines — they're the practical difference between a successful harvest and a compost bin full of rotted colas. We've seen growers in northern Europe pull excellent results from La Blanca outdoors, even in seasons that would have wrecked less hardy genetics.
New growers: start here if you want something from the white family. She's more forgiving than a standard White Widow and more productive than most beginner-friendly strains. Five seeds per pack gives you room to learn without pressure.
Frequently Asked Questions
Is La Blanca an indica or sativa strain?
La Blanca is an indica-dominant hybrid. Her genetics come from Great White Shark, Snow White, and White Widow — all indica-leaning strains. The effect is described as a strong, balanced physical stone with a mental component, consistent with her indica heritage.
How long does La Blanca take to flower?
La Blanca has a flowering period of approximately 8 weeks. This is on the faster end for a high-yielding indica-dominant strain, making her a good choice if you want to keep cycle times tight.
What yield can I expect from La Blanca feminised seeds?
In good conditions, La Blanca can produce up to 500 grams per plant. Outdoors with full sun and ample root space, some sources report yields reaching 600 grams per plant. Indoor ScrOG setups typically produce the densest canopy coverage.
Is La Blanca suitable for beginner growers?
Yes. La Blanca is fairly easy to grow, with strong mould resistance and good tolerance for colder conditions. She doesn't demand precise environmental control, which makes her forgiving for first-time growers. A ScrOG net indoors is recommended but not required.
Can I grow La Blanca outdoors in a cold climate?
La Blanca handles colder conditions well and has strong mould resistance — two traits that matter enormously for outdoor grows in northern Europe. She can reach up to 3 metres outdoors, so plan your space accordingly. Low-stress training helps manage height in smaller gardens.
What does La Blanca smell like?
Skunky and pungent, with sweet, earthy undertones. The white-family genetics come through strongly in the aroma. During flowering, a carbon filter is strongly recommended for indoor grows — she's not subtle.
Does La Blanca produce both THC and CBD?
Yes. La Blanca is noted for producing high levels of both THC and CBD, which is relatively uncommon. This dual-cannabinoid profile contributes to the balanced character of the strain's effect.
