What size MH for my veging area?

Growclean,
So you changed the plans from one 400 to two 600? Have you bought the lights yet?
If you're going to completely fill that area...then the 400mh is a little weak. I prefer MH for vegging but some people do use hps.
Since it's a rectangular area...you'll either want a rectangular hood or better would be two lights. Two 400mh would be a killer veg area in that space. The two 600hps is a little overkill and not really the correct spectrum though you could use conversion bulbs in them.

600w hps with mh conversion bulb works wonders...dont ever use 400s there junk better off using led

Oh, come on Aeroguerilla...
People have been using 400mh for years and back in the day when Sea of Green was developed, the 400watt MH was the standard bulb and is still used a lot. How can you possibly say that 400mh are junk? I know you have no data to back that up...because there isn't any.
Now if you had said LEDs are junk...I'd believe that.

I am voting for the 600 for veg with a conversion bulb.. And you want to veg your plants to 2'-3', wow dude, those are going to be some huge plants when done flowering...

Hi Guys,
I do have to admit that a 600hps with conversion bulb would give you the maximum flexibility for your buying dollar. But one bulb over a 2x6 area makes for poor coverage.
That's why I suggested 2 400s.
And Surfr's right. If your plants only double in size...you're looking at 4'-6' trees.

yeah I didn't bother to mention the space, I would go with a 4x4 or 3x3 veg area with a 600..
data to back me up? ha comeon now ive seen multiple grows under 400's and they are JUNK waste of TIME if u want growth at a proper rate you at very least need a 600...

The veg space should be determined by the flowering space (6x2=12sqft) and style of grow. You have narrowed down the size of the cuts (2'-3'), but...
what style will they be grown in?
How many will you need?
How often?
This will give way to determine the most efficient use for your allocated space, then you can add the lighting accordingly.
aeroguerilla, are you pulling our leg? You better pull up your britches, ignorance is showing on your hiney!

Thanks to all the replies (especially EvilTwin, you always seem to help in my posts!).
MSG,
1.Soil grow to start (this is our first indoor grow).
2.12 plants max to start with, bigger plans for the future. (Legal grow, hence limitation on number and want for maximum growth per plant.)
3.As often as possible I suppose. We have 12' ceilings, so tall trees are no problem, that is why we were planning on at least 6'.
I don't really understand the 400MH vs 600MH conversion bulbs thing. So the 600w that we are looking at are not "true" MH? By the way we were hoping to use 8" hoods just for simplicity sake since our HPS will have 8" openings as well.
Thanks and Pics in another thread soon!
well lets put it this way theres no such thing as a 600w mh you need to get a 600w hps with a conversion bulb to mh. this will work wonders for you. MSG my hiney is showing and you can kiss it

gc considering your other variables imo et nailed it a few posts up. Two lights will cover the rectangular space much better than one. In your case one side is three times longer than the other, so it is almost mandatory unless you would like to get a light mover/rail. That size space would do well with anywhere from 800 to 2000 total watts, but for the plant count and size you mention anything over 1000 total watts would be overkill.
2 400's will cost you more then 1 600w with a conversion bulb and light track... i still say 600 is more efficient... 1.cost 2.rate of growth 3. less wattage.. let the ignorance shine

everyone will have a different view on what is efficient, and until tested in the garden only the gardener will know. There is no point to argue efficiency for an imaginary garden with unknown factors. These are just merely suggestions we give to the imaginary garden questions that frequently pop up. Did you not notice my questions to help me better answer in the first place?
your ignorance I refer to was to all people who enjoy quality canna from 400 watt hid's, nothing more. please do not bring opinions of what is efficient to cloud your nieve perception about weather or not a 400 is "junk". nice you like the light track idea also, but when you think about it...6' is quite the distance to trek isn't it?
grow up, and to the original poster I did not intend to take off topic. I will refrain from posting in here.

A handful of friends and I have tested the 400w for grow, also tested the 300w led 600w mh and i will tell you the 400w is 3rd on that list...
MSG you are a waste of life. take your rude comments and stick them right up your loose asshole. I am trying to help the kid out not stall him on his grow. how bout you grow up? yea you should stop posting here cause you dont know shit

Yeah! That is my hope.... 6 footers!
So we are getting one 600w MH to start. Lumatek ballast with a sunpro(?) bulb. Thanks for the help everyone!

Good luck on the grow growclean...
If you find the single bulb doesn't cover the area well, stick a light mover on it.
Hope those trees come to pass.
