Lycaste × Smeeana (Epiphytic/terrestrial hybrid orchid, lot of 15 in vitro plants)
1. Identification and Origin
Scientific name: Lycaste × Smeeana (hybrid between Lycaste skinneri and Lycaste deppei).
Origin: Horticultural hybrid, parent species are native to Central America (Guatemala, Honduras, Mexico).
Natural habitat: Cultivated under controlled conditions, inspired by the shaded and humid habitats of the parent species.
2. Appearance
Size: Compact to medium plant, 25–40 cm in height.
Pseudobulbs: Oval, slightly flattened, light green to yellowish, 6–10 cm long.
Leaves: Plicate (folded), leathery, dark green, 15–30 cm long.
Flowers: Large (10–15 cm in diameter), often pink, purple, or white with a lip marked by darker spots. Light and pleasant fragrance.
Blooming: Mainly in spring or early summer.
3. Cultivation Conditions (Lot of 15 in vitro plants)
Temperature
Day: 18–24°C.
Night: 12–15°C (day/night drop promotes blooming).
To avoid: <10°C or >28°C.
Humidity
Ideal rate: 65–80%.
Tip: Maintain high ambient humidity, especially during active growth. Use a misting system for the in vitro plantlets.
Light
Intensity: Filtered light (10,000–15,000 lux), such as an east window or under greenhouse shading.
To avoid: Direct sunlight, especially in summer.
Watering
In vitro: Keep the medium slightly moist, avoid standing water.
Post-deflasking / Post-transplanting: Regular watering to keep the substrate moist, but without excess.
Fertilizer
In vitro: Diluted nutrient solution (1/4 dose) every 2 weeks.
Post-deflasking / Post-transplanting: Orchid fertilizer (1/2 dose) during active growth.
Ventilation
In vitro: Light air circulation to prevent mold.
Acclimation: Gradually increase ventilation after transplanting.
Substrate
In vitro: Sterile agar-agar gel medium with tailored nutrients.
Post-deflasking / Post-transplanting: Fine bark + perlite + charcoal for good drainage.
Repotting
Ideal period: After 6–12 months in vitro, when roots reach 3–5 cm.
Substrate: Draining mix (fine bark, perlite, charcoal).
