I've grown this plant from seedling to its current state. The conditions have been as follows: sunlight in the day, constant CFL light underneath a lamp during the night - the lamp is about 6-8 inches from the plant. For the first few weeks I was using an incandescent lightbulb inside a lamp by my computer. So its been about two months and although my plant has some vegetation, etc... and I've repotted it - the stem still seems very thin. When will the stem begin to thicken? What should I use to make the stem grow larger and give more support? Thanks... pictures can be seen in my gallery.
