Regular seeds produce both male and female plants (roughly 50/50), while feminized seeds produce only females. Regular seeds are preferred by breeders who need male plants for pollen production. Feminized seeds are preferred by growers focused solely on bud production.

• Regular — 50% male, 50% female; needed for breeding
• Feminized — 99.9% female; maximizes bud yield

Sex becomes visible during pre-flower, typically 4-6 weeks into the vegetative stage. Female plants develop white hair-like pistils at branch nodes, while males produce small round pollen sacs.

• Female signs — White pistils (hairs) emerging from calyx at nodes
• Male signs — Small round clusters (pollen sacs) at nodes
• Timing — Check daily once plants show pre-flowers; remove males before sacs open

Regular seeds require less specialized production. Feminized seeds involve additional breeding steps (colloidal silver treatment, selective pollination) that increase production costs. Regular seeds are produced through natural pollination, making them more affordable.

Beginners can grow regular seeds, but they need to learn how to identify and remove male plants. This adds a step that feminized seeds eliminate. If you are a first-time grower focused on producing buds, feminized or autoflower seeds may be a simpler starting point.

Buy at least 2.5 times the number of female plants you want. Regular seeds produce approximately 50% males and 50% females, so for 4 female plants you should start with 10-12 regular seeds to comfortably account for male removals and any germination failures.

• Small home grow (4 females) — Start 10-12 regular seeds; expect 5-6 females after sexing
• Breeding project (10+ females) — Buy 25+ seeds for genetic selection; keep the best males for pollen
• Mother plant selection — Start 15-20 seeds to find one elite phenotype worth cloning long-term
• Cost comparison — 12 regulars at $4/seed = $48 for ~6 females ($8/female) vs. 6 feminized at $8/seed = $48 for 6 guaranteed females
