Begonia Pot 9cm
Finish Bulking/Flower Initiation: Optimum conditions during the vegetative period, beginning at transplant, needed for the root to reach the edge of the container AND to make the plant receptive to flower initiation.
Description
Finish Bulking/Flower Initiation: Optimum conditions during the vegetative period, beginning at transplant, needed for the root to reach the edge of the container AND to make the plant receptive to flower initiation.
Media:
- pH: 5.5 – 5.8
- EC: 1.5 – 1.75 Light: Provide 3,500 – 4,500 foot candles (12 – 20 total mols or 35,000 –45,000 lux) to hasten flower induction. Supplemental lighting under low light conditions at 350 – 450 foot candles (35,000 – 45,000 lux) will enhance shoot and root growth.
Temperature: 68° – 70°F (20° – 21°C) nights, 64° – 67° (18° – 19°C) days for 14 days or until roots have reached the bottom of the container. Then temperatures may be lowered to 62° – 65°F (16° – 18°C) day and night.
Average Daily Temperature (ADT): 67°F (19°C)
Moisture: Alternate between moisture levels wet (4) and medium (2). Allow soil to reach level (3) before re-saturating to (4).
Humidity: 40% – 70%. Provide horizontal airflow to aid in drying down the media through evapotranspiration, allowing better penetration of oxygen to the roots.
Fertilizers: Feed at 100 – 150 ppm nitrogen. Under high light conditions, apply an ammonium-based feed (17-5-17). Under low light conditions, apply a calcium-based feed (14-4-14). Under high light and long or extended days, an ammonium-based feed (20-10-20) is preferred. Watch for low calcium and magnesium levels, which may result in stunted, chlorotic plants with marginal leaf burn.
Fertilizer: Potassium nitrate.
