Hi all,

I've been lurking in here for a while now and picked up a lot of tips so I'm really enjoying the Autos rather than the Photo's I'm used to.

Special mention to AutoBeast by the way because his topping tutorials have helped me Imensely!

Anyway... Here's the thing...
I currently have a 2m x 2m tent and 2 600w parabolics. I usually just run 2 the so one starts it's 18 hours at midday, one at midnight, so they overlap for 12 hours during the night for warmth and it's never completely dark. I leave the other sode of the tent as dead space.

Anyway, I'm hoping to change things up and run 4 600's, but due to heat/cost etc, I can't run all 4 for the 18 hours.
My plan is to run the lamps 12/12 so costs don't jump up much and to alternate them diagonally... So if you image the 2x2 footprint of the tent and divide it into quarters, the top left and bottom right would run midday to midnight and the bottom left top right runs midnight - midday.
This way, each plant would get 12 hours of direct over head light and 12 hours of sidelighting/overspill light per day, so never truly in the dark.

What do you think? Could this work? Would it be effective?
