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, Pacific Northwest, New England, Great Lakes, 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.
