How Many Plants to Flower Under Two 150w HPS?

Going to use either 1 gal or 3 gal smart pots (I have both) and under two 150w hps in a 5x2 foot area. I was thinking having 4 plants in 3 gal pots in flower at all times & stagger harvest every 3 weeks.

ok, I did not mean to be a dick or nuttin!

In that case I would flower 2 at the most under each of those lights. But I would also add T5 and cfls to the mix...or f'it and go up to 250w or more and keep the other 2.
of course cooling and ventilation may be an issue as well...so the T5 and cfl add-ons may be a good idea...or maybe an LED or 2....bottom line the more light the better.

I'm squeezing a 4 flowering plants under a 100w mh and 2 125w cfl and that's pushing it... big time. But my tent is only 2x4x5

So 2 plants per 150w in flower in 3 gal pots will be acceptable?
I'd go for 5 gal if it can fit. 3 will work just fine though. If you water once every 2 days or less i would up-pot to a 5 gallon to make things easier in flower. Should be able to get them bulbs close with a decent spread.

@superbak3d thanks, that would be an amazing harvest & goal to reach. I'm going to start practicing LST on some 1 gal bloomers in the meantime, but my clones will go straight into 5 gal smart pots.
