Ace of SpadesEffects & Experience
Ace of Spades is best known for relaxed, sleepy, happy. The effects come on within the first 10 minutes and settle into a stable plateau that lasts 90 minutes to two hours at typical doses. Growers and users consistently note that the high stays true to its profile rather than drifting, what you feel in the first 20 minutes is what you have for the next 90.
Growing Ace of Spades
Growing Ace of Spades fits indoor growers in compact spaces; indica genetics stay short and bushy without aggressive training. Ace of Spades 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: defoliate strategically on day 21 of flower; remove fan leaves blocking interior bud sites without stripping the plant; and feed cal-mag from week 2 onward at 2-3 mL per gallon, most reverse-osmosis and soft tap water setups need it. The most common challenge growers report is late-flower humidity if your indoor RH climbs above 55% during the final two weeks.
