[Market-farming] compact flourescents for plant starting

I got a 400 watt unit (Hydrogarden) 2 years ago. My reading of the catalog
(Peaceful Valley) was that it would light a much larger area than it does.
It only does a good job on a 4x4 foot area, and that is with mylar
reflectors.  My plants were leggier under it than they are under
flourescents, so I am disappointed.

I understand the metal halide are the most efficient, and in a color temp
that seedlings will most readily utilize. They are very hot though.

I'm curious - how large an area do you anticipate the $250 system will
cover?

I'm not happy with the traditional 4 foot shop lights, but they are
$16 complete with 6500k bulbs.
