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 day length 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. SatinCoat ™ 5–6 weeks 1 No 4 days 74–76 °F (23–24 °C) Required for germination
