Well im getting 3 free 400 watt hps lights because they were stolen and my friend can't hold any hot items in his house anymore...

So i was wondering, why do people use weak lights during veg, then stronger lights during flowering?..

Is that a must?.. Can i just use a HPS for the whole grow?...

Thanks..
