This is less then 2 weeks to the far left is tobacco the middle and right lavender lady type. I use a heat mat and light with all my seeds I keep a light on from the start. 16 off 8 on threw the night. Then I open the blind to let sun light in hoping to speed up the. Harding process. Its a west facing window and only gets shaded light. Lots of oak trees and the sun is at about 4 o'clock. The light is set 2 or 3 inches and the mat at 75. From doing this I've gotten 90 or more gen rate. In the 72 cells I have green onions,chives,crimson bunching onion, lav and about 14 diffrent peppers.
