Best Lights for indoors?

Just wondered which are the best lights for indoor 600-1000w(with heat cooling and it being illegal and wanting to get the best out of the wattage)?

What is your budget, how many plants, and how much space?

about 5 or 6 meters each way, money isnt a problem and plants depends on the amount of watt 1 per 100

bump please

In my experience, nothing beats a 1000 watt hps for flowering. However, a lot of people like 600's due to there overall efficiency. But, when it comes down to it, a 1000 watt sitting a foot off your canopy is going to provide a lot more usable light radiation than a 600 watt hps. I guess it depends on what you're trying to achieve with your grow space.
-most efficient is a 600 watt hps
-If the heat issue takes precedent, 600 watt HPS
-if you want the biggest baddest top buds, 1000 watt hps
Again this is just my opinion.
Also, generic bulbs are the best bang for your buck.

600 are more efficient and more than enough for personal grow assuming you don't smoke/use more than 1/8 or so a day( or more if you can get over 0.5 g/w)

6x 600W = 3600w or 4x 1000W = 4000w

Either of those will draw a lot of power, but should fill your space. Light movers might be a good idea as well.

you meant to adjust height?

It's a rail that moves the light side to side.

im a tent grower.

5 or 6 meters eatch way ..thats a pretty big tent !

no i mean i had 5x6m ok space, im going to have only 2m tents but a few

2m X 2m each tent? That's a big area to fill with a 1000w. Most 1000w setups are rated for 1.5m X 1.5m, but should still fill most of a 2m X 2m well.

For flowering, IMO and many others, a 600watt HPS will work u wanders. I flower 5 plants a time under 1 600Watt HPS. GW

Use 50 - 60 watts/sq ft.

I use 600's. I think over all they are a better light. Less heat and less elect.
