3 or just 2.. would be better??

i'm starting a new room it will be 8'x8'x8' and i'm only going to grow 10-14 plants in the room.. i will use the rest of the space for equip. (resovior and fans, ect.) i wasa thinking about what type of lights to use and i still can't deciede.. i was going to use 600watt lights then i couldn't deciede to use 2 or 3 seperate fixtures in the room... then i was thinking would 2 1000watts be better or would i get less coverage.. i've been reading and it says that the 600watts are more efficient compared to 1000 watts.. can someone give me some help with this.. also i will start flowering at around 16" in a soil grow.. i will not be using cooltubes becaues i can buy more fans and vent to the outside..

Draw the outline of the area your plants will be flowered in say 5x4??--20 square feet--50 watts a foot=One 1KW lamp......50 watts per square foot of flowering canopy is right-on......Since plants will end up as bushes about 4'tall if flowered around 16" you will want the 1kw for penetration or the bottom buds will be light and airy

well each pot will be 1' in diameter (round pots) i was thinking about 5x5 which would be 4 rows of 3 in the 5x5space

That will work with 1-1kw light....keep them closer together (in a 4x4 space) and spread them out as they need room, also rotate outer plants with inner to keep growth even.

would 2- 600watts be better or just as good because i could give them a little extra room to grow by having 2 seperate lights..

better yes, 1kw in a square 5x5 is giving only 40watts per foot(closer to 50 is better)......reflectors tend to throw a rectangular pattern so that with the added watts would be great

hmm... i was just thinking.. i could get 3 and have one more row.. that would give me a 5'x6' space which would =30 and divide that into 1800watts would = 60 watts per foot.. that would be nice.. how much would 1800watts running 12 hours a day put my electrical bill up? becaues i wolud have 3 maybe 4 fans in that room to control heat and then a veg room running 8 floresent fixtures and 2 fans..and the regular power i use in the house... so would that raise the bill alot more?
