Treasure IslandEffects & Experience
The dominant effects of Treasure Island are relaxed, happy, euphoric, and the experience is more nuanced than a simple high/low/sedating label would suggest. Onset is gradual rather than abrupt, the peak holds for roughly an hour, and the comedown is smooth — which is why this strain shows up in so many "daily driver" lists from experienced consumers.
Growing Treasure Island
Growing Treasure Island fits temperate and southern Canadian zones — coastal BC, Southern Ontario, and the Niagara region with mild September weather. Treasure Island 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: apply low-stress training in week 2 of veg — bend the main stem horizontally and tie down to expose lower nodes; and defoliate strategically on day 21 of flower; remove fan leaves blocking interior bud sites without stripping the plant. The most common challenge growers report is over-feeding nitrogen past week 1 of flower — switch to bloom nutrients within 7 days of seeing pistils.
