Every region has a different answer to when the box should arrive. Here is the whole map in one read.
Late May, almost universally: the last-frost line crosses the region's big metros between mid and late May, and October ends the party by the second week. Order in mid-April, harden through the third week of May, and favor cuts that finish inside nine weeks of flower. Minneapolis and Buffalo trim a week off both ends; Cincinnati and St. Louis add one back.
The upper South, Virginia through Missouri, opens in mid-April and runs into late October, one of the country's most generous windows, humidity being the tax. The West Coast splits: coastal California plants most of the year, the Pacific Northwest opens mid-May and races October rain, and the finish line matters more than the start line north of Portland.
It runs on heat avoidance instead of frost avoidance. Phoenix and Tucson order by March to establish roots before the June furnace, or order in July for a monsoon start and a frost-free autumn finish. Albuquerque and the high desert add altitude rules: a full hardening week before mile-high UV and wind protection staged in advance. Summer porch heat, not winter cold, is the region's delivery hazard.
Short, bright and abrupt: plant after Mother's Day, harvest by early October, and expect hail insurance in between. Denver's calendar is the template, with mountain towns subtracting further weeks by elevation. Fast-finishing indicas rule the region, the computed picks on the clones near me state pages already respect that, and every arrival gets a full hardening week under that thin-air sun.
