Cannabis plants are either male or female. Only female plants produce the buds (flowers) you're growing for. Feminized seeds are bred to produce female plants almost exclusively, so you're not wasting space, time, or resources on males that need to be removed. All of the seeds we sell are feminized.

Photoperiod varieties flower in response to a change in light schedule. Outdoors, they begin flowering naturally as days shorten in late summer. Indoors, you trigger flowering by switching to a 12-hours-on/12-hours-off schedule. They typically take longer to finish but give you more control over plant size and yield.

Autoflower varieties flower automatically based on age, usually finishing 9-12 weeks from seed regardless of light schedule. Given Ohio's outdoor season of late May to early October, autoflowers that finish in 8-10 weeks are a practical and reliable choice for outdoor growers. Not sure which is right for you?

CBD (cannabidiol) and CBG (cannabigerol) are non-psychoactive compounds found naturally in the cannabis plant. People commonly report CBD as calming and supportive for sleep, stress, and everyday discomfort. CBG is often described as more clarifying, associated with focus and a lighter sense of ease. Both are widely used as alternatives to pharmaceutical options for mild anxiety, inflammation, and pain.

Many growers find that blending CBD or CBG varieties with THC varieties produces a more balanced experience. Growing your own gives you direct control over what goes into your plants. Check out our Strain Selection Guide to explore our hemp varieties.

Ohio allows up to six plants per adult, with a household cap of twelve. Unlike most states, Ohio's limit is per person — two adults sharing a home can legally grow twelve plants between them. Ohio does not distinguish between mature and immature plants; all six count equally regardless of growth stage. Read the full Ohio home grow law breakdown for details.

Yes. Outdoor, greenhouse, and indoor cultivation are all permitted. Outdoor plants must be in an enclosed, secured area that is not visible from a public space. An open backyard visible from the street does not meet this requirement — a locked greenhouse, fenced and gated enclosure, or similar structure is needed. Use our zone map to find your planting dates. For the full breakdown, see our Ohio home grow laws guide.

No. Any adult 21 or older can grow at their primary residence without a permit or medical card. Landlords can prohibit cultivation in lease agreements — check your lease before you grow. Selling homegrown cannabis without a commercial license remains illegal. Read the full Ohio home grow law breakdown for complete details.

Senate Bill 56 was signed on December 19, 2025, and took effect March 20, 2026. For home growers, the core cultivation rules stayed the same — six plants per person, twelve per household. The law added new restrictions on possessing cannabis purchased in another state and made other changes to possession and consumption rules outside the home. A referendum effort was underway as of early 2026 that could put portions of the law before voters in November 2026. See our Ohio home grow laws guide for the full picture.

Most of Ohio falls in USDA Zones 5b-6b, with southern Ohio reaching Zone 7a near the Kentucky border. The outdoor season runs roughly late May to early October, giving growers a workable but not generous window. Autoflowering varieties finishing in 8-10 weeks are the most reliable outdoor option across the state. Short-season photoperiod varieties finishing in late September to early October are viable in Zones 6-7. A greenhouse extends your season on both ends and satisfies Ohio's enclosure requirement. Enter your zip code on our zone map for specific dates, then browse autoflowering varieties or short-season varieties.

Most Ohio outdoor growers start seeds indoors in late April and transplant outside after the last frost, typically mid-May in southern Ohio and late May further north. Autoflowering varieties can be started later since they are not dependent on day length. Remember outdoor plants must be in a secured enclosure — plan your outdoor setup before germinating. Check your zip code on our zone map for specific frost dates, or see our germination guide for step-by-step starting instructions.
