Lighting

I'm looking to grow 10 plants. Planning on an ebb flow system using a 5 gal controller bucket, and 2 gal plant buckets. What would be the best light setup? I was thinking 2 600w HPS, or would one 1000w cover this? Either way, the lights would need vented through the tube, right? Thanks.

anyone have suggestions? thanks.

1 1000 watt would work or 1 600 watt would work.

you'll need something like 100w of light per sqf. you can look up specs on the lights it will say something like a 400w is good for 4x4 area and so on but take a foot off what ever they say and go for a bit of over kill. More light= beter bud.
