Do you think I'm losing growth at this current stage with just the CFL? I mean, I know I'm certainly not pushing it to it's limits, but I don't think the plant is necessarily starving for light either. It's a 45 watter, at 5500k color temperature. So far it's nice and green, and the spacing between the nodes is short. The "canopy, " if such a small plant can be said to have one, is relatively equidistant from the bulb itself, so I figure it's making the best use of the light it has. Do you think getting a "Y" splitter socket fixture and an additional bulb is necessary, or should I just hold out for the LED?
