Re: Light spectrum

[Mike Rigby <vitrotec@HOTMAIL.COM>]

Dear Hrishy

Advice I got from a very helpful engineer at Thorn Lighting here in
Australia was that, of all the standard fluorescent tubes, "cool white"
tubes were the closest to the absorption spectrum of plants.

They also make a very cheap non-dimmable electronic ballast.
