Buying cannabis seeds online in Hawaii: the federal rules
Under the federal law in force today (the 2018 Farm Bill), cannabis seeds with no more than 0.3% delta-9 THC have been treated as hemp, as the DEA said in informal letters in 2022. A new federal hemp definition takes effect on December 11, 2026, unless Congress delays it again, and it excludes viable seeds from plants above 0.3% total THC. Regulators have not yet said how they will apply it to seeds. Once a seed germinates, state law decides whether you may grow it. Read the federal section of our US guide.
Growing season and climate in Hawaii
For registered patients, Hawaii's climate allows growing almost year round, since there is no frost at low elevations. Conditions change sharply over short distances: the windward sides of the islands are wet and humid, while the leeward sides are drier and sunnier. Day length varies little through the year, so photoperiod plants grown outdoors tend to flower sooner and stay smaller than they would on the mainland. Upland areas on Maui and the Big Island are noticeably cooler.
For patients allowed to grow, these sativa-leaning picks suit Hawaii's steady warmth, and Quebec Cookies, tolerant of common pests and mold, is the one for the wetter windward sides.
- Durban Poison – pure sativa, about 18% THC, ready mid-October outdoors
- Quebec Cookies – bred by QCS, 70% sativa, 19–25% THC, ready late October outdoors, tolerant of common pests and mold
- NYC Diesel – bred by QCS, sativa-dominant, up to 24% THC, ready late October outdoors
Harvest dates and THC figures are ranges from our strain pages, not promises: results depend on the grower, the method and the season’s weather.
