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 but give 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. Oklahoma's long outdoor season supports both types well, though autoflowers offer flexibility for growers who want faster harvests or multiple runs per season. Not sure which is right for you? See our Strain Selection Guide.

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.

Yes. Home cultivation requires a valid OMMA medical marijuana patient license. The good news is Oklahoma has one of the most accessible programs in the country — there is no list of qualifying conditions, and any Oklahoma-licensed physician can recommend cannabis for a patient they are treating. The biannual fee is $100 ($20 for Medicaid, Medicare, or SoonerCare patients). Applications are submitted online at oklahoma.gov/omma. Telehealth evaluations are widely available.

Licensed patients may grow up to six mature plants (flowering) and six seedling plants (nonflowering) at any one time, for a total of twelve plants. Once a plant begins to flower, it counts toward your mature plant limit. You may also legally possess the harvested cannabis from your home grow in addition to standard possession limits. Read the full Oklahoma home grow law breakdown for details.

Yes. Both indoor and outdoor grows are permitted. Plants must be grown on property you own or have written landlord permission to use, and cannot be visible from any adjacent street to a person with normal 20/20 vision. A fenced backyard, enclosed greenhouse, or secured outdoor space that blocks street view all meet the requirement. Use our zone map to find your planting dates. For the full breakdown, see our Oklahoma home grow laws guide.

Yes, if you rent. Plants must be grown on property you own or on property where you have the written permission of the property owner. Get that permission in writing before you plant — a written addendum to your lease is the cleanest approach, though a documented written confirmation from your landlord also works.

Oklahoma spans USDA Zones 6-7 with a long outdoor season running from late April through October in most of the state. The warm climate supports both full-season photoperiod varieties and autoflowers comfortably. The main outdoor challenges are summer heat stress in July and August and occasional humidity-driven mold pressure in late summer. Heat-tolerant genetics with good mold resistance perform best outdoors. Enter your zip code on our zone map for your specific dates, then browse our full-season varieties, short-season varieties, or autoflowering varieties.

Most Oklahoma outdoor growers start seeds indoors in late March to early April and transplant outdoors after the last frost, typically mid-April in southern Oklahoma and late April to early May further north. Oklahoma's long season means full-season photoperiod plants have plenty of time to finish before the first fall frost. Autoflowering varieties can be started later or run multiple cycles per season. Check your zip code on our zone map for specific frost dates, or see our germination guide for step-by-step starting instructions.
