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. Because Rhode Island's security requirements effectively favor indoor cultivation, autoflowers offer an efficient, fast-finishing option that maximizes your three-plant allowance.

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.

Rhode Island allows three mature plants and three immature plants per dwelling unit under R.I. Gen. Laws § 21-28.11-22. This is a per-dwelling-unit limit — it does not increase based on how many adults share the address. Rhode Island's limit is among the most restrictive in New England. Read the full Rhode Island home grow law breakdown for details.

Effectively, yes. Rhode Island law requires compliance with Cannabis Control Commission security requirements, which include keeping plants in a locked space that is not visible from outside. An open backyard garden does not meet this standard. A locked grow tent or locked grow room is the most practical path to compliance. Outdoor grows are difficult to bring into full compliance under the current rules. See our Rhode Island home grow laws guide for the full breakdown.

No registration or permit is required for recreational home cultivation within the legal limits. If you rent, Rhode Island law allows property owners to restrict or prohibit cultivation — get written permission from your landlord before setting up a grow. Read the full Rhode Island home grow law breakdown for complete details.

Because Rhode Island's security requirements effectively make indoor cultivation the default, variety selection should be guided by your indoor setup. Compact autoflowering varieties are a strong choice — they finish quickly, stay manageable in size, and let you turn over multiple harvests per year from three plants. High-yielding compact indicas and indica-dominant hybrids are also well suited to maximizing a small plant count indoors. For outdoor growers with a compliant locked enclosure, Rhode Island spans Zones 6a-7a with an outdoor season running late May through early October. Find your zone here. Browse our Strain Selection Guide for help matching a variety to your setup.

For indoor growers, you can start seeds any time of year since you control the environment. For outdoor growers with a compliant locked enclosure, Rhode Island's last spring frost is typically mid-April to early May in most of the state. Most outdoor growers start seeds indoors in late April and transplant after the last frost.
