The specs in one line: 21-26% THC, <1% CBD, 42-49 days flowering, 500-600 g/m² reported. Best indoor or outdoor. moderate grow.

Lineage: Crystal WW (EGS genetics) — this one traces back to White Widow ancestry, which explains the resin production that shows up well before the end of a 42–49 day flower window. That's a short run for feminized seeds, and growers working indoor setups under tight schedules tend to notice it. THC tests regularly land between 21–26%, so expect a heavy-hitting result rather than a casual afternoon smoke.

Yields sit in the 500–600 g/m² range indoors, which is solid output for a moderate-difficulty grow that also performs reasonably in outdoor Canadian conditions during a long summer. Flavor profile leans earthy with a underlying sweetness — nothing flashy, but clean and consistent across harvests. The plant responds well to low-stress training if you want to push that canopy yield closer to the top of the range.

Best suited to intermediate growers who want reliable numbers without babysitting a difficult cultivar through a long season.

Genetics & Lineage

Crystal WW traces its genetics to Crystal WW (EGS genetics). This hybrid-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Herbies Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily euphoric and relaxed effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 26%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Crystal WW delivers THC levels of 21-26%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing Crystal WW

Crystal WW is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 42-49 days with yields of 500-600 g/m². Plants typically reach 80-150 cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Crystal WW features a earthy, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Crystal WW is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
