The seedlings poked through the soil on day 8 and appear healthy green color. It is still very cold outside (southern Ontario), so we have put the seedlings under T5 6400K lamps that are suspended 6 inches above the pots. The lights were purchased locally from Astral Grow as a kit by SunBlaster. We have them on 18/6 cycle set by a manual timer. The lights come on at 6 am and turn themselves off at midnight. They are not overly hot lights, but they do provide slight temperature warmth for the soil to be optimal for the growth. On day 12, the seedlings are growing their second set of leaves. I water them every other day with about 50 ml/per plant of room temperature water.
