Did you find that cost effective? I tried growing under artificial

justify the extra early and late crops

[long description of growing setup deleted]

....I use a 125 watt compact fluorescent grow light and
keep it on about 16 hours per day.....it works out at about five pounds
per
month

I don't mind the capital cost, I'll quite happily bear that, but
its the running cost that I object to I was working on the assumption
that in order to compensate for a lack of summer sunlight I would need
to provide the equivalent of about 1 kw / m2 which rapidly gets too
expensive. How large an area can you grow under a 125w setup?

With my set up I can cover an area of 2 1/2 feet by 8 feet when connected to
the overhead track which moves the light back and forth....when in this mode
I use 20 hours per day...when stationary it covers 2 1/2 x 2 1/2 but a
little more if using the outer zone for low light stuff like lettuce....H
