Depending a little on when you start counting your days (Is it when you put the seed into the ground? Is it when the seed sprouted in your paper towel? Is it when the plant surfaced?) Depending on this, your plant is slightly stunted to very stunted. At 1 month, the plant should be about a foot tall, quite bushy, and re-potted once or twice into at least a 1 gallon container.

How close are those lights?
