Purple 43Effects & Experience
The dominant effects of Purple 43 are relaxed, focused, calm, 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 Purple 43
Growing Purple 43 fits shorter outdoor seasons — Atlantic Canada, the Prairies, and northern BC — where 7-9 week flowering finishes ahead of October rains. Purple 43 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: top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola; and apply low-stress training in week 2 of veg — bend the main stem horizontally and tie down to expose lower nodes. The most common challenge growers report is training timing — top at the 4th node, not earlier and not later, for the best canopy distribution.
