OK, so not a good idea to mess with the timing, i can understand that. Of course, ENVIROLITES.. why didnt i think of that ? My local hydro shop sells em in blue and red, presumably blue is best for veging ?
I have tried veging under flourescents over the years, but the plants became quite stretched and spindly. My 600w on the 12 cycle runs on a light rail over 6 foot or so, but i agree that using the 2 600's would make for a better yeild.
Will rethink my growroom.
Thanks for info.

volak Reviewed by volak on . ELECTRICITY SAVING I saw my electric bill today, not good. I currently have 2- 600w HPS, one on an 18 cycle, the other on 12. Could I run the 18 hour for only 12 hours, with say, an hour ON in the middle of the dark cycle to prevent flowering ? It WOULD save electric, but would i get enuff growth ? Comments appreciated. V.
