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 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. Illinois has a workable outdoor season for both types in most of the state, though autoflowers are a smart choice for growers who want faster harvests or are working within a limited plant count.

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. Illinois legalized recreational cannabis in 2020 under the Cannabis Regulation and Tax Act, but home cultivation rights were not included in the recreational framework — they are reserved for registered medical cannabis patients. If you have a qualifying condition, obtaining a medical card is the path to legal home cultivation. The qualifying conditions list is broad and maintained by the Illinois Department of Public Health. Read the full Illinois home grow law breakdown for details.

Registered medical patients may grow up to five plants per household that are more than five inches tall under 410 ILCS 705. This is a household limit, not a per-patient limit — multiple patients living at the same address share a single five-plant maximum. Seedlings and plants under five inches tall do not count toward the limit. Read the full Illinois home grow law breakdown for details.

Yes. Both indoor and outdoor cultivation are permitted as long as plants are in a locked, enclosed space not visible from public view, and minors cannot access the grow area. If you rent, you need written permission from your landlord before growing. Use our zone map to find your planting dates. See our Illinois home grow laws guide for the full breakdown.

The qualifying conditions list is broad and includes cancer, chronic pain, HIV/AIDS, glaucoma, hepatitis C, lupus, migraines, multiple sclerosis, neuropathy, PTSD, spinal cord disease, and many other debilitating conditions. The full list is maintained by the Illinois Department of Public Health. Patients 18 and older can apply directly; patients under 18 require a parent or guardian to apply on their behalf.

Illinois spans USDA Zones 5-6, with Chicago and northern Illinois in Zone 5b and southern Illinois reaching Zone 6b. The outdoor season runs roughly late May through late September in most of the state. Illinois summers are warm and humid, so mold-resistant genetics are worth prioritizing for outdoor grows. With only five plants allowed, high-performing genetics matter. Autoflowering varieties finishing in 9-12 weeks and short-season photoperiod varieties finishing in September both work well. Enter your zip code on our zone map for your specific window, then browse our autoflowering varieties or short-season varieties.

Most Illinois outdoor growers start seeds indoors in mid-to-late April and transplant after the last frost, typically mid-May in southern Illinois and late May in the Chicago area and northern regions. Varieties finishing in late September are the safest outdoor choice — Illinois's late-summer humidity can cause issues for genetics that push into October. Check your zip code on our zone map for specific frost dates, or see our germination guide for step-by-step starting instructions.
