SME 0.9–1.3 mS/cm Comments: Germination temperatures above 72 °F (22 °C) can lead to thermodormancy, which will reduce and/or slow germination) Geraniums are irradiance plants; the more light they receive, the faster they will flower. Under short days or cloudy conditions, it is beneficial to provide supplemental lighting of around 400 foot candles (4,000 lux), especially in the plug tray to speed up flowering. All geraniums are especially sensitive to bacterial diseases so be sure to start with clean plug trays, media and propagation areas. Geranium seed does not carry bacterial diseases; if you start clean, you can stay clean. Do not subirrigate or use recycled water.

128–cell tray pH: 5.5–5.9 SME 0.5–0.75 mS/cm Comments: Under low light conditions provide supplemental HID light if possible; do not extend daylength as this will extend the time to flower. It is critical to allow adequate dry back between irrigations to prevent stunted and distorted growth. Because of this do not mist at night. If germinating on a bench it is best to use a tent system to increase humidity and reduce the frequency of irrigations/misting.
