A hermaphrodite, in cannabis growing, is a plant expressing both sexes, usually a female that produces male flowers or exposed anthers among its buds. Botanists prefer "intersex" or "monoecious expression", because cannabis flowers are normally single-sexed. The self-pollen these plants shed is fertile, so they can seed themselves and everything nearby.
In practice
Look from mid-flower onward for male flower clusters at nodes, or single yellow-green anthers protruding from buds. Check again in late flower. Act on what you find:
- Remove the plant, or at least the affected parts, before anthers open.
- Never use it as a parent.
- Note the cultivar and source; a pattern across seeds from one source is a genetics problem.
GenetixBay standard: zero herms in a 10-plant screening grow for Bay Lines, Seed Club and featuring; "Verified under 2% herm rate" (the founder's threshold) only after about 150 or more pooled community-grown plants. See herm threshold.
Don't confuse with
- Monoecious hemp: a deliberately bred, stable trait in some hemp cultivars.
- Foxtailing: spires of new pistillate flowers, not male.
- Male plant: an XY plant with only staminate flowers.
Myth check
"Late-flower bananas are normal" is wrong. House position: intersex expression is mainly breeder error (repeated selfing, careless feminising, unstable releases), not a natural cannabis trait. Stress reveals susceptible genetics rather than causing healthy ones to switch. 5-10% herms in a commercial operation means poor genetics (Punja & Holmes 2020 observed it; GenetixBay interprets it this way). See hermaphrodites.
A male flower that carries stamens (anthers on filaments) and no functional pistil; in cannabis, five drooping sepals around five pollen-shedding anthers.The pollen-producing part of a stamen; in cannabis each male flower has five anthers that split to shed wind-blown pollen.Bay Lines are GenetixBay's community breeding programme: lines bred from member-nominated keepers and documented males, tested and released with full records.The Seed Club is GenetixBay's seed programme run through a licensed partner, offering tested seed lots with published batch records where the law allows.The herm threshold is GenetixBay's two-tier herm standard: a 10-plant screening grow with zero herms to be featured, then about 150 or more community-grown plants before a line can be Verified under 2% herm rate.Hemp is cannabis grown for fibre, seed or other uses and, in many laws, defined as Cannabis sativa with no more than 0.3% THC by dry weight.A female flower with a pistil but no functional stamens; in cannabis, a bract-wrapped ovary topped by two stigmas.Nanners (bananas) are exposed, banana-shaped anthers on a female flower: a hermaphrodite trait, not a normal part of late flowering, and a reason to cull.Having male and female flowers on separate individual plants; drug-type cannabis is naturally dioecious with an XY sex-chromosome system.Having both male and female flowers on the same individual plant; in cannabis, a trait deliberately bred into some hemp cultivars, not the natural norm.S1 is seed from a plant pollinated with its own pollen; every S1 seed is female and a new genotype, not a copy of the parent.
