table top grow station for phals

[ladyslipper]

Hi all, I only put this thread here as I only grow phals (at least at this moment). Like most northerners, I have to consider falling light levels in the winter & since I still haven't found a grow set up that I can use (due to my mobilitiy issues). I found this set up in lee valley; here is the information: "The tabletop model is 50" x 19" x 24" tall. Requires two 48" bulbs."

My question is, if I place this on a table close to an east, north/east facing window with no shade cloth, will my phals continue to grow in the winter? I think the only problem might be the height from base to ballast.
