Reported effects center on euphoric, happy, relaxed. Deadhead OG pulls toward a balanced state where neither head nor body dominates, a profile that holds up across phenotypes when the seeds are grown to their potential.
Growing Deadhead OG
Growing Deadhead OG fits outdoor growers with at least 130 frost-free days; the balanced structure handles both heat and cool nights. Deadhead OG 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: apply low-stress training in week 2 of veg, bend the main stem horizontally and tie down to expose lower nodes; 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 over-feeding nitrogen past week 1 of flower, switch to bloom nutrients within 7 days of seeing pistils.
