those will work fine, in fact thats pretty much(i get mine from where i work so technically its not the exact same ones,lol) what i do use when doing smaller plants, or 2 liter bottles w/the tops cut off and holes put into the bottom. what kind of lighting are you planning on and how much of the space does it fill up? if you get a cool tubed 400w hps w/a remote ballast so it can be stored outside the grow you should be able to reach your goal once you get everything dialed in. how many plants are you thinking of doing each run? really you still have the same amount of area which you want to be completely filled no matter how many plants it takes to fill up that space so if you do want to do lots of smaller plants in the small 16 oz like you were saying it would be fine, but you'll have to settle for less off of each plant.
