London Pound CakeEffects & Experience
Reported effects center on relaxed, sleepy, happy. London Pound Cake pulls toward physical relaxation and a quiet, observational headspace, a profile that holds up across phenotypes when the seeds are grown to their potential.
Growing London Pound Cake
Growing London Pound Cake fits cooler climates and high-altitude growers, where the compact structure resists wind and the short flower beats early frost. London Pound Cake 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: feed cal-mag from week 2 onward at 2-3 mL per gallon, most reverse-osmosis and soft tap water setups need it; and top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola. The most common challenge growers report is late-flower humidity if your indoor RH climbs above 55% during the final two weeks.
