250W or 400W hps?

Once I have got a couple more cfl grows under my belt, I would like to build myself a perpetual cab.
( 1.7m height x 0.75m depth and about 1.2m in width = +-1m square floor space )
Im guessing 250W will be ideal. My target is around 1.5-2.oz / month, whether that be a 1 plant scrog, or 2, 3 or 4 plants..(or 10 clones)?

Would 400W be pushing it ? even if heating could be controlled?

yes it would be pushing it , and it would make ur light bill higher Id go with a 250W HPS from start to finish will be fine for ur needs and space . Also will be cheaper for u and cooler . So there is more pros then cons id think here for u.
Much luck hope this info helps.
