Less Light During Veg?

I am planning a perpetual grow set-up and was wondering if less light can be used when vegging. If so, how much less?

The flower room is 6x5 and I plan on 3x600w HPS anywhere from 8-12 plants in soil. 5-7 gallon pots.

The veg room is 5x5 maybe 6x6, to veg a max of 12 plants what is the minimum light I can use?

If T5s are viable I am am willing to go that route. As I have never used them how many would be recommended?

I am trying to save money on energy costs.
 
I use VHO t5's, but the light spread is not that great. If you want the minimum that will work nicely to fill that area, I would do 2-400's. 800 watts total. That is not unreasonable, but it will cost you some dough. I run mine 18/4 which works well, and cuts down on energy costs. Good luck

Nothing, they disappear from existence for those 2 hours.
It's a twilight zone thing.

As for the topic.

One 600W should do fine vegging that many plants in that area, just make sure you got a lot of 99% reflective material and a nice hood that spreads the light, and put it high up so its a even canopy.

BOOM! Perpetual.
 
If you are vegging plants for the purpose of budding them you can get away with 18/6d. I have found that 20/4d to 24/0d works best for seedlings just starting out. Now if only I can find a timer with a 22hr day.
