Growing Amherst Diesel
Growing Amherst Diesel fits mild coastal and southern Canadian climates with dry late-summer weather to support the longer flower window. Amherst Diesel 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 over-feeding nitrogen past week 1 of flower — switch to bloom nutrients within 7 days of seeing pistils.
