Chemdog #4Effects & Experience
The dominant effects of Chemdog #4 are relaxed, sleepy, happy, 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 Chemdog #4
Growing Chemdog #4 fits indoor growers in compact spaces; indica genetics stay short and bushy without aggressive training. Chemdog #4 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 - 500 g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 600 - 700 g/plant. Expected plant height is Tall, 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 maintain canopy airflow with an oscillating fan moving air through the leaves, not just above them, to prevent powdery mildew. The most common challenge growers report is late-flower humidity if your indoor RH climbs above 55% during the final two weeks.
