Yield numbers on seed listings are measured under ideal commercial conditions, so a figure like 500 grams per square metre rarely translates to a home tent. Flowering time is usually more honest, though some breeders still shave a week off to look competitive. Comparisons between advertised figures and what forum members actually harvested are tracked on https://kushindicaseeds.com , and the gap for some popular indica strains is quite large. Use the descriptions to compare strains against each other rather than as absolute targets.
