I have planted some petunia seed. Most of them have come up very well. They seem to be just sitting there, not growing. I have some that have been up for almost 4 weeks and haven't seemed to grow at all. I have them under lights, try not to let them dry out and not be too wet. I have started turning the lights off at night for about 6-7 hours. The room cools down to around 67 degrees at night and is 75 during the day. I have started alot, but am getting a little discouraged at the non-growth.
Any help is much appreciated.
