White 99 is an indica-dominant hybrid built for resin and compact bud structure. Growers will find a balanced high that leans toward body effects.
THC sits between 18 and 22 percent, offering notable potency without extreme spikes. That range fits many Canadian growers seeking reliable commercial-grade resin.
CBD is low at roughly 0.5 to 1 percent and supports the strain's psychoactive profile. Medical patients in Canada report benefit for sleep when using THC with low CBD.
Growing difficulty rates as intermediate for nutrient and training demands. In Canadian indoor rooms focus on humidity control to avoid mould.
Flowering runs 8 to 10 weeks under standard photoperiod. Outdoor harvest often finishes by late September in temperate zones.
Yield is medium to high with strong resin production. Expect about 450 to 600 grams per square metre indoors and 400 to 700 grams per plant outdoors under good light.
Plants stay medium in height with dense branching. Indoor heights typically range 80 to 150 centimetres while outdoor plants may reach 1.5 to 2 metres.
White 99 performs well indoors under SCROG or SOG setups. Outdoors it prefers sheltered, sunny sites with good airflow.
Initial effects bring mental uplift and improved focus for tasks. That shifts into deep body relaxation and sleepiness later in the session.
Genetics come from White Widow crossed with AK-47. That mix explains heavy trichome production and balanced potency.
Seeds are feminized to reduce male offspring and simplify runs. MasterSeeds offers these for growers who want predictable female plants.
Best climate runs temperate to warm with stable light cycles. In cooler regions start outdoors after the last frost or move plants inside for full control.
