Sour BubbleEffects & Experience
Reported effects center on relaxed, sleepy, happy. Sour Bubble 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 Sour Bubble
Growing Sour Bubble fits cooler climates and high-altitude growers, where the compact structure resists wind and the short flower beats early frost. Sour Bubble 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 16 oz/m2 under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 19 oz/plant. Expected plant height is Medium (5 to 8 FT), 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 training timing, top at the 4th node, not earlier and not later, for the best canopy distribution.
