Do i really need 3x600watt hps?

Hey again guys, quick question regarding my setup.

Grow information and setup.

Tent: 2mx2mx2m (4mSquared)
Extractor: 5"vortex fan with 5"carbon filter.
Intake: 6" inline fan ducted from AC unit (positive pressure) for the time being.
Lights: 2x600 watt hps
Strain: 6 Blue cheese from clone.
Growing medium: Biobizz Allmix
Pots: 5gal fabric
Nutes: Canna terra vega for veg. Canna flores + pk 13/14 and booster for flower.

Atm im at day 29 since potting the clones and still in veg for another 3-4 weeks.

Basically i had hoped to use 3x600watt hps lights, 2 to each light during flower. However i dont think i will be able to pull that off with temps sitting between 25-28 degrees with just 2 lights on i have tested with 3 lights which takes my avg temp up to between 28-32 degrees which from what ive read is to hot for flowering. My question is do i really need 3 lights for flower to get high yields from 6 plants or is that abit overkill? I have trained my plants for an even cannopy just want to know will the 2 lights have enough spread for 6 rather bushy plants within that tent size?. Atm i have 3 plants to a square metre so there is still another 2x1m space to use. Im thinking if i put my 2 lights more central will that be enough light for all plants ill add a pic of the setup atm. Any advice and info greatly appreciated as always.

See how they are beginning to overlap? I dont want them fighting for the light.

Riteo, cheers lol

If you flowered now you would do well with 2x600. I understand it's tempting to veg longer but they should stretch a bit in early flower. =p I think you're better off with less heat. Good luck with it all.

I got plenty of room for them to veg more from what ive read on the strain they will double in size at the most. Ive worked out my maximum height befor i flip based on the double in size so im good for them to nearly double in height from what they are in the pic before flip. Do you think if i moved my 2 lights more central in the tent rather then having them covering just half the tent the light would cover all 6 plants when they are twice the size they are now?

Heres a pic to show you what i mean if i have my setup like this will 2 lights be enough to flower 6 big girls?

Looks good to me man. Maybe move the trays out of the middle so they can be a little closer in to the middle of the light's footprint. =)

Way ahead of ya bro literally just moved the trays in the middle before reading your post lol they are only there to help keep humidity up as im running AC unit ducted in wont need them during flower anyway thanks for you're help man much appreciated

No sweat man just dabbing it up this morning, lurking the forums. =)

Haha im lurking everday, wouldnt have got this far if it wasnt for this forum. Great community here
