The only way to co2 to be effective,is if all other aspects of the grow are at their maximum potential..Temps and humidity,lighting and feeding all must be optimum for the co2 to have an effect.Personally with a couple 400W lamps I wouldnt be using co2,then theres the problem of sealing the attic.Wont co2 escape through the eaves?

hate to be negative, but I've got better yield with 1x400, so I think you should look at optimising what you have now, do a few more grows, then maybe think about co2 when you have everything else 100% right. skeletor's spot on imo.
