    i would do 6 - 9 girls under these lights in a 1 x 1 x 2m space :)
    as for yeild it depends on the grower + strain + other factors :)
    i have 8 under a 400 atm, check it out in my siggy and maybe get a glimpse at ur future :)

    i done 3 cheese in soil under 400w with 9oz yield last year,like the other guy said there is no real answer to the question,i suppose more plants = less veg time though.i would use 600w,400w is ok but imho its all about the lights and the method of growing,if you are only using 400w lights then i would consider a scrog grow with 4 or 5 plants you will make better use of the light. 003.jpg this pic is 5 plants under 1 600w hps the were vegged for just over 4 weeks

    some nice healthy plants ya got there, is that a DR tent?.. with a 400 i agree, top and train. you can get nice bud with a 400 but the light doesn't penetrate too far, gotta keep it cool and close. ive seen friends run 400's in 4x4 tents get the same yield from 10 as they did from 4. for what thats worth

    600 aircooled? is that a typo or did you decide to upgrade? at that distance with a 600 its like running a 1k, imo better. gonna get some chunks out that bad lad.. and nice buds delvite, i love seeing those even canopy's full of bud.

    yeah you can see the aircooled shade in the picture,the ballast goes to 650w if you turn it up to superlumes setting which i have been doing since week 2veg.they can never have too much light! buds are getting big now and im feeding them as much as they will take,iv had to lift the light up a bit now the canopy is full to get even spread of light,but i would allways keep it as close as i can get without burning during early veg,this picture taken this morning(4weeks exactly in flower) so plenty more time for them to fatten up.thanks for looking 006.jpg grow 1 012.jpg

    i was confusing you with the OP sorry hah. 12 ounces seems to be a fairly consistant number ive heard from 400w growers, wheather they have 10 plants of 4. no co2 or anything special
