Has anyone done this? My boss wants us (myself and colleague) to grow
tomatoes in the greenhouse for him over the winter. We have good heating
in
there, and sodium lighting. Has anyone attempted this before, if so, how
do
we do it?

TIA


you might want to do a search on Hydroponics,
seem a lot of it done under HPS lamps.
