I had a few thoughts pop into my head while reading this topic.
Quote:
The roots do a
great deal of their storage developing at night when the green sections of the plant are not being pressured by the light to produce and distribute the day's excess sugar to the roots.

Does 24 hour lighting affect the surface area of the roots negatively by not allowing the plant to store as much excess sugars in the roots and thus stunting or slowing root growth or positively by maintaining a constant room temperature and hence a constant root temperature.

In essence, plants will grow better with a high average 24-hour root temperature that is constant rather than fluctuating.

Also another thought was that in indoor gardens when the lighting is turned off the temperature drops. I would assume this would also impact the surface area of the roots negatively, well not necessarily negatively but in the sense that they could have more to gain like you said from a constant root temperature. My thought was; Is this enough for someone with an indoor garden to consider alternatives, maybe modify the system to support a more constant temperature during the night cycle of either stage to enhance root growth.[/list]
