About Growing Outdoors in New York
New York has a humid continental climate with warm summers and cold winters. The growing season varies significantly from Long Island (longer) to the Adirondacks (shorter). Indoor growing is recommended for beginners to avoid frost timing issues. Autoflowers are excellent for outdoor grows due to the shorter season.

Autoflowers win in New York's outdoor season
Photoperiods need a specific light cycle to flower. Autoflowers don't — they finish in 8-12 weeks regardless. For short outdoor windows, this is the safer bet. See our full autoflower roundup and save 15% at Fast Buds with code HGAPP.
Pro Tips for New York Outdoor Grows
Autoflowers are forgiving
Autoflowers finish in 8-12 weeks regardless of light cycle. In New York's shorter outdoor window, this is often the safest choice for beginners.
Watch the last frost
Transplant AFTER Late April - Late May. A single frost night can kill young plants. When in doubt, wait another week.
Cover if a cold snap comes
Keep row covers or a portable greenhouse ready if your forecast shows unexpected cold nights in early or late season.
Harvest before first frost
Your first frost typically arrives Early October - Mid November. Harvest before this or frost will damage your buds. Check trichomes daily in the final 2-3 weeks.
