Growing Great White Shark
Growing Great White Shark fits shorter outdoor seasons, Pacific Northwest, New England, Great Lakes, where 7-9 week flowering finishes ahead of October rains. Great White Shark 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 up to 800 g/m2 under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 900-1000 g/plant. Expected plant height is Short, 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 flush nutrients in the final 10-14 days for cleaner flavor; trichomes finish properly even on plain pH-adjusted water. 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.
