How to Grow Felina
iNaturalist
Felina
Cannabis sativa L. (hemp cultivar)
herbFelina is a European hemp cultivar bred for high fiber content and low THC levels, making it legal to grow in many jurisdictions. It produces tall, sturdy plants with minimal branching and is primarily cultivated for its strong bast fibers used in textiles, construction materials, and rope production.

Germination
1-2 weeksSeeds sprout and first cotyledons emerge from soil
Keep soil consistently moist but not waterlogged. Seeds germinate in 7-10 days at optimal temperatures (50-70°F)
Seedling/Early Vegetative
3-4 weeksSmall plants with true leaves developing; rapid vertical growth begins
Thin seedlings to proper spacing early. Ensure adequate light and maintain soil moisture. Light fertilizing can begin
Vegetative Growth
4-6 weeksTall, slender plants with minimal branching; strong stem development occurs
Apply nitrogen-rich fertilizer to support stem growth. Monitor for pests. Maintain consistent watering. No pruning typically needed
Pre-Flowering/Flowering
2-3 weeksPlants reach full height; flowers begin to form on inflorescences; pollen production in males
Reduce nitrogen, increase potassium. For fiber production, harvest before full seed maturity. Monitor male plants if seed production not desired
Harvest Readiness
Peak harvest window is 1-2 weeksPlants reach full height (typically 3-4 meters); stems are mature with peak fiber quality
Harvest when stems show color change and seed pods mature. Cut plants near base. Retting (water or field retting) follows harvest for fiber separation

Uses
Textile and Rope Production
CraftFelina's bast fibers are among the strongest plant-derived fibers, used to produce durable textiles, canvas, rope, and cordage. The long, strong fibers make excellent material for heavy-duty applications. [source]
Building Materials and Insulation
HouseholdHemp fiber from Felina is processed into hempcrete, insulation boards, and composite building materials valued for sustainability and thermal properties. These materials are increasingly used in eco-conscious construction. [source]
Paper and Pulp Production
CraftHemp fibers produce high-quality paper with superior durability compared to wood pulp, useful for specialty papers, currency paper, and archival documents. [source]
Biodegradable Composites
HouseholdFelina fiber is incorporated into bioplastics and natural fiber composites for automotive and consumer products, offering sustainable alternatives to synthetic materials. [source]
Seed Oil and Nutrition
HouseholdWhile Felina is primarily bred for fiber, its seeds contain nutritious hemp seed oil rich in omega-3 and omega-6 fatty acids, with minimal THC content. [source]
Harvest Tips
For optimal fiber quality, harvest Felina when the lower leaves begin to yellow and seeds reach the milk stage—typically 70-110 days after planting depending on latitude. Cut plants at or near the soil surface with a scythe or mechanical cutter. Immediately begin the retting process (soaking in water or laying in fields for 2-4 weeks) to break down pectin and separate valuable bast fibers from woody core. Spread stalks evenly for field retting to ensure uniform moisture exposure. Complete drying before processing into fiber.
Fun Facts
- 🌱 Felina is named after a female cannabis plant and was developed in France; it's one of the EU-approved hemp cultivars with THC content below 0.2%, making it legal to cultivate across Europe
- 🌱 Hemp grows incredibly quickly, reaching 3-4 meters (10-13 feet) tall in a single season and can produce more fiber per acre than trees, making it an exceptionally renewable resource
- 🌱 The retting process (breaking down pectin in stalks) can take 2-4 weeks in water or 3-6 weeks in the field, and improper retting results in poor fiber quality, making timing and technique critical for successful cultivation
