Sour Tsunami CBDEffects & Experience
The dominant effects of Sour Tsunami CBD are relaxed, calm, focused, and the experience is more nuanced than a simple high/low/sedating label would suggest. Onset is gradual rather than abrupt, the peak holds for roughly an hour, and the comedown is smooth — which is why this strain shows up in so many "daily driver" lists from experienced consumers.
Growing Sour Tsunami CBD
Growing Sour Tsunami CBD fits medical and wellness growers in any Canadian climate — CBD genetics tend to be hardy and forgiving. Sour Tsunami CBD 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: flush nutrients in the final 10-14 days for cleaner flavor; trichomes finish properly even on plain pH-adjusted water; 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 calcium and magnesium supplementation under bright LED lighting; cal-mag at 2-3 mL/gal from week 2 prevents the most common deficiency.
