What White Widow is
White Widow is a hybrid cannabis strain. It was bred in Amsterdam in the 1990s by Shantibaba, who worked at Green House Seeds at the time. Breeder notes list two parents: a sativa from Brazil and an indica from South India.

The name refers to resin. By harvest, trichomes cover the buds and the small leaves around them. Under light the plant reads white.
Numbers to know
- Type: hybrid
- THC: 15% to 25% in published lab tests
- CBD: under 1% in most samples
- Flowering time: 8 to 9 weeks indoors
- Indoor yield: 400 to 500 grams per square meter
- Outdoor harvest: late September to early October in USDA zone 7 and warmer
- Terpenes: myrcene, alpha-pinene, beta-caryophyllene
Numbers shift with grower, light, and lab. A package label that says 25% THC reports one sample, not a promise.
White Widow Strain High Effects: What to Expect
Reported effects
Users describe a fast head high, then a body settle. Reports list euphoria, talkativeness, and relaxed muscles. Some users report dry mouth, dry eyes, and anxiety at high doses.

White Widow is sold for stress, pain, and appetite in states with medical programs. Clinical evidence for strain-specific effects is thin. Most human studies test cannabis as one category, not named cultivars.
Why convenience drives the sale
White Widow has sat on dispensary menus since the 1990s. A buyer today gets it four ways: flower by the gram, pre-rolled joints, vape cartridges, and concentrates. Some shops sell clones. Seed banks sell photoperiod and autoflowering versions. The auto version finishes 9 to 10 weeks from seed.
That spread changes the purchase. A shopper who wants a set effect can pick a form that fits the plan: a pre-roll for a walk, a cartridge for a small dose, flower for home. Menu prices differ by state and shop. Cartridges and edibles carry more cost per milligram of THC than flower.
Legal status in the US
Cannabis is a Schedule I drug under the Controlled Substances Act. A DEA proposed rule to move it to Schedule III was not final as of 2025. State law governs sale. Recreational sale is legal in 24 states and the District of Columbia. Medical programs operate in 38 states. Check state rules before you buy.
Growing notes
White Widow grows in soil or coco. It responds to topping and low-stress training. Indoors, keep humidity under 60% in veg and under 50% in flower. Dense buds hold moisture, and moisture invites mold.
Bottom line
White Widow is a hybrid with medium to high THC, a 8 to 9 week flower cycle, and a long record on store shelves. The genetics are old. The packaging is new. Convenience, not novelty, keeps it moving.
