Wow dude... I wrote up a reply, and I turned off the computer... sorry, stoner part of the day.

Anyways, what I wrote, more or less, was:::

I read something like this a couple of months ago (probably on OverGrow)... it was an idea for switching ON/OFF your lights...

Say, you have a big area of plants, with 12 lights over them (2rows). Well, 1st stage you turn ON 6 lights... (3lights per side)... then, next stage, you turn ON the other 6 lights, and turn OFF your initial ones.

I don't know if it helped simulate "nature" or something... the general "thought" on the document was that it increased yields and saved some energy.

When I start using both of my bulbs (MH + HPS), I'm planning on doing something like that for the flowering 12/12 cycle... I thought of starting up both bulbs, for 2 hours... then, cycle them.

Maybe this helps:::

(12 hours total)
2hr MH + HPS [total=2]
1hr MH [total=3]
1hr HPS [total=4]
4hr MH + HPS [total=8]
1hr HPS [total=9]
1hr MH [total=10]
2hr MH + HPS [total=12]

What you think?
