These figures are ranges, not promises. Flowering time, harvest date and yield vary depending on growing conditions: the grower, the method and the season's weather. "Mold resistant" means mold tolerant: less prone to mold and slower to be affected. No strain is 100% mold resistant. How we set these numbers →
Taste & Aroma Profile
Earthy, herbal, pungent, spicy and woody, with a lemon note on some phenotypes, on buds so frosted they look dusted with sugar — “it smells so strong”, as one reviewer says.
About White Widow
Genetics & strain profile
White Widow is the Dutch classic of the 1990s — Brazilian Sativa crossed with a South Indian Indica — named for the white coat of resin that covers its buds. Ours is a sativa-dominant hybrid whose THC can range from 15 to 25% depending on the grow, with very little CBD, and it carries our beginner-friendly badge because it tolerates a wide range of environments and growing styles. It has 15 reviews averaging 4.2 out of 5, one grower diary on GrowDiaries, and a place among our best sellers. The best review is a full grow log: “S/W Ontario: 3 of my girls topped out at or over 1 kg each — germinated late February under 600 W, transplanted mid-May in living soil, topped, LST and lollipopped, trellis-trained, flowered mid-August, ready early October, no PM or pests to speak of”; others weighed “221 g from 2 plants” and “226 g of so stony mess”. The honest notes: one buyer had 3 of 5 seeds germinate, and one grower who bred his own second-generation seeds got males and hermaphrodites — which, as another reviewer explained, is what happens to seeds from a feminized plant and is not a fault of the originals. Seeds that do not germinate are covered by our guarantee. Our seeds are guaranteed.
How White Widow grows
Indoors it typically flowers in 8 to 10 weeks with 300 to 400 g/m² on average; good airflow helps prevent mould and mildew, especially in humid climates, because the buds are dense and resin-heavy. It takes training well — the kilo-per-plant grower topped, tied down, lollipopped and trellised his — and it is forgiving of beginners’ mistakes in feeding and watering. Outdoors, plants can yield up to 500 g each in a sunny, well-kept spot and far more in the ground with a long veg: start indoors in late winter, transplant in mid-May, and expect flowering from mid-August and harvest in early to mid-October, which in southern Ontario and Quebec means watching the forecast in the last two weeks. The 1 kg grower reported no powdery mildew or pests; most growers find it one of the sturdier outdoor plants. Phenotypes vary a little — one reviewer saw straight-haired and curly-haired plants and a big lemon smell in his five seeds. Soak seeds 12 to 24 hours and plant directly in warm, barely damp soil.
Taste, aroma and effect
Earthy, herbal, pungent, spicy and woody, with a lemon note on some phenotypes, on buds so frosted they look dusted with sugar — “it smells so strong”, as one reviewer says. The effect is well balanced: an energizing, clear-headed lift with a gently relaxing body, the reason it has been a coffee-shop staple for thirty years, and at up to 25% THC strong enough to start small. For its relatives, see CBD White Widow, Purple Widow and our own Quebec White; for the other great Dutch classic, Northern Lights.

J'ai démarré les 5 semences commandé et seulement 3 sur 5 ont germé. J'ai donc esseyé de les faire germer d'une autre méthode que celle recommandé mais sans succes. heureusement que ces 5 grainne venais avec le cadeaux autrement j'en aurais eu seulement 3. J'ai deja commande a multiple reprise et jamais eu ce meme probleme c'est peut etre la genetique.

Just finished up my first grow. Pop 2 of these with one of the free seeds that came with my order. The free one failed to sprout. The 2 WW however shot up great. After cutting and drying and trimming I ended up with a total of 221g of bud from 2 plants in around 5 months. I'll be. Smoking good until my next grow. Can't fault these seeds 4 stars because the others seed I bought from here failed and they sent me replacements.

@eric - The issues you describe are not a fault of the seeds.
1 - You said second generation. If you are using seeds from harvested plants, those seeds genetics will be broken down with each generation. You will get herms and males at this point. Do not use those seeds.
2 - If you choose to use those seeds, you just need to watch your plants when they mature. Cull any males so they do not pollinate your females.
It would have been better to rate the product and not your mistakes.

The yield is very high. The 5 seeds grow out different flower types, with straight hairs, curly hairs, and a big lemon smell. The white hairs are not harvested for almost 10 weeks. After two generations, it is found that there are male and female plants, which is harmful. All the 500 trees in my room have seeds, and the loss is huge.
Sorry this one didn't turn out as hoped. Every pack is covered by our guarantee: delivery is guaranteed, germination is guaranteed at 80%, and if your seeds didn't pop or the wrong pack arrived we re-mail a replacement — no arguments, just contact us.

Final results of white widow fem, indica phenotype, very large colas, thc 15-18%
7.5 oz at 63 days, super soil, ph 6.2 @ 7-900 ppm
Sweet mild skunk flavor, long lasting relaxing high, I decided it is good enough to keep for a while , I still have four more seeds, every seed will be a little different. that's how we gind the fire strains. I have kept strains for 12years continuous, I am searching for the keepers. This takes so much time and discipline

My first of 5 seeds is very very big producer, itis only 26 inches tall and easily has 224 grams
I don't know about the potency yet, the smell is nice but mild, it really doesn't have a lot of trichomes so hopefully it will still be potent
