Growing Silver Haze
Growing Silver Haze fits subtropical and Mediterranean climates with dry late-summer weather to support the longer flower window. Silver Haze 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 400g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce Up to 450 gr. Expected plant height is Tall, with intermediate cultivation difficulty. Practical tips that move the needle: defoliate strategically on day 21 of flower; remove fan leaves blocking interior bud sites without stripping the plant; and top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola. The most common challenge growers report is training timing, top at the 4th node, not earlier and not later, for the best canopy distribution.
