I'll shed some light for ya. You're attitude will screw you around here. You sound impatient, immature, entitled and lazy. It sounds like you expect people to jump whenever YOU want something, without putting in any effort. I'm guessing you're under 25 YO?
Sq ft coverage, light coverage, # of plants per light, etc are all heavily covered and discussed in multiple threads here, not to mention, hundreds of independent articles. You aren't doing anything new or different. Shouldn't take more than 15mins to figure out your answers.

Seems like I wound a few people up for simply saying that no one seemed to want to shed they're personal experience on my questions, oh well no drama, thanks for the few of you that actually gave me some answers though! 
for the rest, chill smoke a doobie and I promise I'll do my research

Cool! I have previously only used hps lighting for veg and flower, good buds mind but much longer internodes on plants, even pure indica varieties., so I'm using two 600w metal halides for seedling&veg and 1x600w MH and 1x600w hps for the first 2-3weeks of flower, then 2x600w hps for the remainder of flowering, sound good?

Do you mean 4 individual metal halide 600w?? I have 7x7ft of growing space that I intend to use two 600w metal halides to grow 9 bushy plants, hence the MH lighting for vegging.

Hell you can keep ur 200$ lol it's only what £145 Anyways right? If u wanna be a dick about it lol

Veg no problem, but your two mh 600s will only adequately flower at most a 3.5x7 canopy during flower. I've vegged a 10x10 with a 600mh but a single mh 600=3x3 canopy during flower.

Yeah that's all I'm using the MH lighting for, the vegging, and then a mix of 1600w hps and 1 600wMH for first two weeks of flower, then two 600w hps for the rest of flowering.

A 600 hps still will only get you to like a 3 x 3.5 max. I'd still say 3x3. So flowering with 2 you might get 3.5-x8 canopy. So if you're flowering a 7x7 your yields is really hurting on the side by not adding the extra 1200 watts

Yeah I get it but I'm using really efficient reflectors, adjust a wings with spreaders on them, so I would think from what I've read in Jorge Cervantes books and Greg greens grow bible two 600w hps lights will be pretty good to light up 7x7ft of space for flowering 9/10 plants, what do you think?

Lol. Light output is light output. You can spread it out, but you lose intensity. You could stick a 600 hos in a magnum xxl and it would still cover, at best, a 3x3.5 effectively. You could literally double your yield in you're space if you doubled the light. 4 600s in a 7x7 is about perfect. Not too much nor too little light at any point in the canopy. Whats your yield like in that 7x7? Anywhere near 4lbs? Because thats not a good yield in a 7x7 and I really doubt your pulling 4 pounds with 2 x 600s, but your space would easily fit that, probably closer to 6, which is a decent yield with 4 x 600s. So I guess it really depends on what youre trying to get out of your space, but 2 x 600 watt hid lights do not effectively cover anywhere near a 7x7 Duri g flower.

2 600s won't flower a 7x7 very well. Poly off the plants area down to 4x7. Run the 600s side by side, 4 plants under each. Scrog.

Lol., OK granted light output is light output I understand, I've accurately measured my space now and it's more Like 6ftX5.5ft so by your theory of a 600w hps covering a 3ftX3.5ft grow space during flowering, two of them old cover 6ftX7ft during flower?? I'm growing all from seed, they all have similar flowering times as one another too so I hope that will work to my advantage., also don't you think I would have trouble with heat running 4x600w hps in such a small space? It already gets too hot in there with one 600w but the inline fan helps dramatically., and as for yield I've only grown 4 plants from seed in one go before, but I've done that about five times with id say good results, usually pullin around 12Oz dry depending on which strain and how long I veg of course, haven't had a chance to try and yield 4lbs yet so who knows
I might invest in another dimmable ballast just to add another 600w lamp to the room just to top up in light, would using a bare bulb hanging vertically just from the mogul socket be good for some extra light as I don't have the room for anther reflector I don't think..?

How did you get 3x3.5 x 2 is 6x7 ft? With two you either get a 3x7.5 or 6.5x3.5 depending on how you place the rectangular shaped hoods...Lol., OK granted light output is light output I understand, I've accurately measured my space now and it's more Like 6ftX5.5ft so by your theory of a 600w hps covering a 3ftX3.5ft grow space during flowering, two of them old cover 6ftX7ft during flower??

Heat is always in a grow, it just has to be managed properly. I've run a 600 in a 18"x30" tent with no heat problems and no Ac, just really good ventilation and a decent ambient temp.
I yield anywhere from 1.5-1.7gpw with my 600s, but my systems are pretty dialed. If you have crazy reflective surfaces you may be able to stretch a 600 to a 3x4 area. My 3x5 runs great with a 600 in it, but I run a 2x4 tray so I'm not expecting my canopy to actually max out the 3x5 space. You should be pulling at least a pound per 600, that's not really very good when you have your system dialed. 1.5 is average for a decent grower and a 600 watt light. For reference a pound with a 600 is around .75 gpw.

I saw your post the other day, just figured I'd let someone else answer it, being a rather simple question. Maybe others thought the same thing. Might be hard to get a 6' spread with 2 lights though. Probably better to either use 2 smaller 4x4 tents or get 4 lights. Since you already have the tent, I assume, guess you need to get a couple more lights. Could get 2 400w HPS, then you'd have a nice mixture.
