Cannabis Seeds for South Carolina Growers

Yes. Cannabis seeds are legally classified as hemp under the 2018 Farm Bill. The seed itself contains no meaningful THC regardless of what the plant would eventually produce, so purchasing seeds — including high-THC feminized varieties — is legal in South Carolina. Triangle Seeds ships cannabis seeds directly to South Carolina customers.

Yes. Triangle Seeds ships cannabis seeds to South Carolina home growers. Orders are packaged discreetly and typically go out within 1-2 business days. Questions about your order? Text or call us M-F, 10-6 EST at (919) 410-6945.

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 as days shorten in late summer — across most of South Carolina, that means harvest in October. Indoors, you trigger flowering by switching to a 12-hours-on/12-hours-off schedule. They give more control over plant size and yield but take longer to finish.

Autoflower varieties flower automatically based on age, finishing 9-12 weeks from seed regardless of light schedule. South Carolina's long frost-free season can support multiple autoflower planting cycles per year for licensed growers, and autoflowers are particularly useful for timing harvest ahead of late-summer humidity in the coastal Lowcountry.

CBD (cannabidiol) is a non-psychoactive compound found naturally in the cannabis plant, commonly reported as calming and supportive for sleep, stress, and everyday discomfort — without the high associated with THC. CBD seeds are the primary variety grown commercially under South Carolina's SCDA hemp permit program. The Pee Dee region and the coastal plain are well-suited to both fiber hemp and floral CBD hemp production. Home growers can purchase seeds now to be ready if South Carolina legalizes cultivation rights in the future. Browse our CBD seeds or use the Strain Selection Guide to find the right variety.

No. Cannabis cultivation is treated as manufacture under South Carolina law and is a felony at any scale. There is no medical cannabis program and no decriminalization in the state, so there is no legal framework that would protect any cultivation for personal use. Cultivation of 10 pounds or less carries up to five years in prison and a $5,000 fine. Cultivation of 10 to 100 pounds escalates to up to 25 years and a $25,000 fine. Growing within a half mile of a school adds a mandatory one to two years on top of any cultivation sentence. Many South Carolina residents are purchasing seeds now to be ready if and when that changes. Read the full South Carolina home grow law breakdown.

No. South Carolina is one of only eight states in the country with no functional medical cannabis program. The only cannabis-related patient access in the state is Julian's Law — a 2014 law allowing patients with intractable epilepsy to use low-THC, high-CBD cannabis oil. Beyond that narrow exception, there is no legal path for any South Carolina resident to obtain cannabis for medical use within the state.

Julian's Law, named after a child with epilepsy, was passed in 2014 and allows patients with intractable epilepsy to access low-THC, high-CBD cannabis oil. The product must contain at least 15% CBD and no more than 0.9% THC. Critically, Julian's Law does not create any dispensary program or licensed in-state supply chain. Qualifying patients must obtain the product through their own means — typically from out-of-state sources where legal. The law provides a limited affirmative defense but no clear path to legal in-state access. It is the entirety of South Carolina's patient cannabis access.

The South Carolina Compassionate Care Act is a carefully crafted medical cannabis bill championed by Republican Senator Tom Davis of Beaufort. It would establish a pharmacist-dispensed medical cannabis program for patients with one of 12 debilitating conditions, with approved products including edibles, tinctures, vaporization oils, and topical balms. Smoking and home cultivation are explicitly prohibited. The bill passed the Senate in February 2022 — and again in February 2024 on a 24-19 vote — but died in the House Medical Affairs Committee both times. The current version, SB 53, was introduced in January 2025 and is stuck in the Senate Medical Affairs Committee. Senator Davis is expected to reintroduce similar legislation in 2027 if SB 53 does not advance.

Yes, with a hemp farming permit from the South Carolina Department of Agriculture (SCDA) — but two restrictions set South Carolina apart from most states. First, the application window is only open from January 1 through approximately late February each year. There is no rolling or year-round application process. The 2026 window has already closed; the 2027 window opens January 1, 2027. Second, only South Carolina residents are eligible to apply — out-of-state operators cannot obtain a South Carolina hemp farming permit. All applications are online-only at agriculture.sc.gov/hemp. Before applying, you must obtain an IdentoGO background check and a USDA FSA farm number. See the full South Carolina hemp permit walkthrough for details.

The total annual cost is $1,100 in fixed fees:

Application fee: $100 non-refundable, paid at submission.

Permit fee: $1,000 per year, paid after approval.

Additional costs include an IdentoGO background check (required each year), and pre-harvest THC testing paid to the SCDA Residue Laboratory or another approved lab. A late fee applies to applications submitted after the main February deadline but before the grace period closes in early March. South Carolina's $1,000 permit fee is among the highest in the Southeast — comparable to Alabama's per-site fee.

South Carolina spans USDA zones 7a through 9a. The Upstate region including Greenville and Spartanburg falls in zones 7a and 7b, the Midlands including Columbia sit in zones 8a and 8b, and the coastal Lowcountry near Charleston and Hilton Head reaches zones 8b and 9a. The outdoor growing season runs from mid-April through late October in most of the state, with the coastal areas offering an even longer window. South Carolina's warm summers and mild autumns make it a strong outdoor hemp-growing state — the Pee Dee region in the northeast is one of the state's traditional agricultural heartlands and well-suited to floral CBD production. In the coastal Lowcountry, late-summer humidity during flowering can challenge floral hemp — mold-resistant varieties with tighter bud structure are worth prioritizing there. Enter your zip code on our zone map for your specific window, then browse our full-season varieties, short-season varieties, or autoflowering varieties.

Across the Upstate and Midlands (zones 7a-8b), start seeds indoors in late March to early April and transplant outdoors after your last frost — typically mid-April. Photoperiod varieties started in April will flower in late August and finish in October. In the coastal Lowcountry (zones 8b-9a), transplants can go out in late March, and the long frost-free season allows multiple autoflower cycles between March and November. Lowcountry growers should factor in summer humidity when selecting genetics. Keep in mind that the SCDA permit application window closes in late February — your permit must be in hand well before spring planting.
