Growing cannabis in Glen Cove: your seeds sprout while March nights still freeze
In Glen Cove, the seedling window opens before winter lets go. A plant meant for an April 21 transplant gets sown between March 10 and March 24, and March still averages about 14 freezing nights, with lows near 35°F.
A seed in cold soil mostly just sits. So before you choose a strain, ask a smaller question: how warm is the spot where it sprouts?
Adults 21 and over: yes. Plant limit: 3 mature + 3 immature per adult; 6 mature + 6 immature per residence.

From a cold March start to a damp August flower
These figures come from the Mineola station, 9 miles away and 96 feet up. A basement or a back bedroom with a cold outside wall can run well below what the thermostat reads in March. Set seedlings on a heat mat, keep the lamp on through the coldest part of the night, and let the dark hours fall in the afternoon. A thermometer at soil level tells you more than the hallway dial.
The same habit carries a winter run. January lows average about 27°F and the station logs about 83 freezing nights a year, so a basement tent loses heat fast once the lamp shuts off. Keep pots off bare concrete on a foam board or a stand. Winter air is the easy part indoors: heated rooms run dry, and only an unheated, damp basement needs a dehumidifier in those months.
Summer reverses the job. July averages an 87°F high and 75 percent humidity, and August matched that damp at 75. Wet air settles in a basement and around a tent once the lamp is off, so a summer flower room wants a dehumidifier sized for the whole room and steady air across the canopy. Lights at night help with July's 7 or so hot afternoons, though nights near 68°F cool a tent only a little.

Planting out on the North Shore
New York law requires home plants, indoors or out, to grow in a secure spot no one under 21 can get into, and none may be plainly visible from public view. The limit is 3 mature plus 3 immature plants per adult, and no more than 6 mature and 6 immature in one residence. A greenhouse or a fenced yard qualifies only if it meets all of that.
If yours does, photoperiod plants started in March go out on April 21. A frost after April 16 comes about one spring in ten, and nights reach a 45°F average on April 21. Autoflowers keep their own schedule, so sow those roughly a week ahead of transplant instead. The season then runs about 193 days to the early first frost of October 31. September averaged 72 percent humidity in 2024 and October 65, so a plant that ripens in early October finishes in drier air, usually well ahead of the first frost. Space plants wide and cut at the first sign of gray mold.
| Last spring frost | Apr 2 in a typical year, Apr 16 to be safe (later only 1 year in 10) |
|---|---|
| First fall frost | Nov 12 typical, as early as Oct 31 (1 year in 10) |
| Frost-free season | about 224 days |
| Nights stay 50°F or warmer | May 8 to Oct 13 |
| Start seeds or clones indoors | Mar 10 to Mar 24 |
| Move plants outdoors | Apr 21 or later |
Your Glen Cove grow, opened by you alone
Glen Cove is a city on the North Shore of Nassau County, with a downtown of its own and the Garvies Point waterfront. A neighbor may notice a dehumidifier droning through August, and no app can quiet that. What Canna GLAP guards is the record behind it.
Your grow journal is encrypted on the phone before it uploads. Were our servers ever breached, the intruder would come away with grow records they could not read and no key to unlock them. The March heat-mat routine that finally got every seed up is yours to keep.
What is encrypted: your plants, notes, photos, feed logs and harvests. What is not: account details (such as your email, name and plan), a grow name or town if you type one, your team, and your sensors' names. The full list: what a hacker would get.
