Dr. WhoEffects & Experience
The dominant effects of Dr. Who are euphoric, relaxed, uplifted, 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 Dr. Who
Growing Dr. Who fits guerrilla growers and balcony cultivators, since the plant ignores light cycle and finishes before fall rains arrive. Dr. Who runs on an 18/6 light schedule from seed to harvest, autoflower genetics ignore photoperiod, so there is no flip and no light-cycle change. Indoor yields land around up to 300 g/m2 under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce up to 300 g/plant. Expected plant height is Short, with intermediate cultivation difficulty. Practical tips that move the needle: maintain canopy airflow with an oscillating fan moving air through the leaves, not just above them, to prevent powdery mildew; 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 calcium and magnesium supplementation under bright LED lighting; cal-mag at 2-3 mL/gal from week 2 prevents the most common deficiency.
