1000 watt on a light rail?

I heard somthing about the 1000 watt hps can only yeild so much? What about if it's hooked up to a light mover that's constently moving does that increase my number?

it allows you to put more plants in an area wich in turn gives you a more even and bigger cannopy if u put a mover on a 1000 watt its like having 2 1000 watt lights hung and the 1000 watt hps will yeild fine its just that the 600w are more electricity friendly and the 600w's lumens are around that of the 1000

im thinking about setting up a rail for my 1000 so i can use the full potential of my room and they are only like $110 thats cheaper then a new light setup

That's why I got one. Instead of two lights move just one . So it just as I thought. I have six (sensi) Jack herer and six (dj short) Flo. They were veging for 30 days then now have been flowering for 2.5 weeks. Buds all over every plant all the way through each plant!!!

So how do I get the feed you sent me on my feed?
