WSUEffects & Experience
Reported effects center on relaxed, sleepy, happy. WSU pulls toward physical relaxation and a quiet, observational headspace — a profile that holds up across phenotypes when the seeds are grown to their potential.
Growing WSU
Growing WSU fits shorter outdoor seasons — Atlantic Canada, the Prairies, and northern BC — where 7-9 week flowering finishes ahead of October rains. WSU is photoperiod, which means you control when it flowers by switching from 18/6 (vegetative) to 12/12 (flowering). Most indoor growers veg for 4-6 weeks before the flip. Indoor yields land around 450-550 g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 500-700 g/plant. Expected plant height is 120-180 cm, with intermediate cultivation difficulty. Practical tips that move the needle: flush nutrients in the final 10-14 days for cleaner flavor; trichomes finish properly even on plain pH-adjusted water; and top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola. The most common challenge growers report is calcium and magnesium supplementation under bright LED lighting; cal-mag at 2-3 mL/gal from week 2 prevents the most common deficiency.

WSU FAQ
Is WSU indica or sativa?+
WSU is a indica-dominant with a 72% indica / 28% sativa split. The effects lean toward physical relaxation and a calm, settled headspace.
How long does WSU take to flower?+
WSU flowers in 8-10 weeks once you flip to 12/12 light cycle. Outdoor harvest typically lands in late September to mid-October across most Canadian growing zones.
What is the THC content of WSU?+
WSU tests at approximately 23%% THC when grown to its potential. Real-world numbers depend on grow conditions, harvest timing, and curing — well-grown phenotypes can land at the high end of that range, while poorly cured flower tests lower.
Is WSU good for beginner growers?+
WSU is rated intermediate difficulty. Photoperiod genetics give you control over plant size and harvest timing, which means a bit more responsibility for getting the schedule right. Most growers with one harvest behind them handle this strain without difficulty.
