Flowering Type: Perfection is an Obligate Short Day Plant. Short days enhance flowering.
Specific Flowering Mechanism: Short day treatments must begin the moment of sowing.

PLUG CULTURE
Germination – Optimum conditions for seedling development that begins the day the crop is sown until cotyledon expansion.
Expect radicle emergence 3 – 5 days.
Cover: Seeds may be covered with a thin layer of medium vermiculite to maintain moisture levels.
Media: • pH: 6.2 – 6.5. pH levels <6.0 may induce iron, manganese or sodium toxicity in Marigolds. Symptoms are exhibited on the lower leaves.
Marigolds can be used as an indicator plant for low pH.
• EC: <0.75
Light: Light is not necessary for germination. If utilizing a chamber, providing a light source of 10 – 100 foot candles (100 – 1000 lux) will improve germination
dramatically compared to seed germinated in the dark.
Moisture: Saturated (5) for days 1 – 3 or until radicle emergence. On days 4 – 7 reduce moisture to moist (3). Once actively growing, begin alternating between
moisture levels wet (4) and medium (2). Allow media to approach level (2) before re-saturating to level (4).
Humidity: 100% until radicle emergence then reduce to 40%.
Dehumidify: Provide horizontal airflow to aid in drying down the media through evapotranspiration, allowing better penetration of oxygen to the roots.
Temperature: 72° – 75°F (22° – 24°C)
Average Daily Temperature (ADT): 67°F (19°C)
