this is what i was going to say basically :
Definitely man i myself dont have the spare cash to max out on lumens but if is in your budget go for it man! Ive seen a couple buddies grow with hids @ around 5000 lumens per sqft and have baseball bat colas! I would definitely like to see what 10000 p sqft can yeild! Like a couple people said , just make sure you carefully select your strain. you could have 250000 lumens a sqft but if you dont have a good strain you will still have a less than max yeild.. Good luck man, let us know what you decide on and keep us updated on your grow.
this is what i was going to say basically :
if you have tall plants then use the 1000 cause it will penetrate much deeper into the foliage
if you grow shortish plants then 2 x 600 would give you more bang for your buck
and personally i dont believe you can have too much light, just too much heat
no thats one plant not topor any thing done toit.tahts how i cut mt clones. and that was'nt me cuz i get 4oz to 5ozper plant. this plant is ungodly compared to my last grows when my pant got 7ft indoors and i got 4 to 5 ounces per plant.thats the way i thought about it man, if im going to jail im going to jail doing it the right way u know, i dont want no hassle, no bullshit, 100 percent business about it, cus like u said 1 plant or 100, 1 light or 50, i get busted im going to jail for a long time, i like that pic, is that 1 plant lstd or some shit? also u said u get 3 oz per plant in a 9 plant setup with 1000 watter, that comes out to 27 ounces per harvest every 3 or so monthes, which sounds what im lookin for, cus iwas gonna do 16 and hope for an ounce off each which would be a pound every 3 or so, so i like that idea alot, but could i optimize it with more plants or adding that extra 600 watter, thats the mystery
cuz after this summer im going with 2 600wtt hps and use my 1000forveg. that should GET~R~DONE LOL
2 600w.
Why? Because I run that setup!
Why REALLY? Because with a 4x4 area you can use a MH bulb in the 600w and be just as efficient while vegging. (600w MH is plenty for veg). You can save the 400w used during veg and use 1 light. If you feel its necessary you can end up using both lights to veg.
If you go with 2x600w, you have the option of running 1 MH and 1 HPS. If they're on light movers, you have an amazing combination. Not to mention you can get the 600w closer, more lumens.

between a 1/2 oz and an oz a day hear
i don't i usaly grow 6 at a time.but i fucked up and had these girls outsid in november and the froze. i already buded out 3plantsthat were the worst, thought they were going to die so i shoved themn bloomthe day of the freeze. i have been babying theselast 3 plants to get what i have 2day so i can get that max yeild. welli think im going to get it, LOL i just added my last 2 girlsto the flower room on the 15th. 7 more to take their place.
4x4 is too small of an area to use a light mover, just get a high quality reflector and a single 600 or 1000 is sufficient coverage for that area. 2 600w will be a waste IMO, unless you do what bterz said and use 1 HPS and 1 MH. There does seem to be an advantage running both spectrums during flowering, hence the extended spectrum and dual discharge lamps.
