I have a whole bunch of Tomato Seedlings that I started about five weeks ago. They all have real leaves, but they have not gained much in height. i'd say they are all aobut 2-3 inches tall and staying at that height. I have five diffrent varieties, and they all are behaving like this. They live inside for now, in their own little pots. What can I give to them to encourage thier growth. Right now they are in seed starter soil but when they are replanted they will go into well drained soil that the rest of my veggies seem to like. Our growing season is so short I would like to "force" these tomatos a little in order to be able to harvest out doors, rather than dig them up and bring them in when it starts to frost.
