Reported effects center on happy, euphoric, creative. Fat Purple 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 Fat Purple
Growing Fat Purple fits short outdoor seasons in the upper Midwest, Pacific Northwest, and Northeast, autoflower genetics finish in 70-90 days from seed regardless of latitude. Fat Purple 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 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 60-100 cm, 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 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.
