4x8 or 5x10 tent?

4x8 ~200$ or 5x10 ~350$ tent, which should i get?

upgrading from a 4x4 (now veg room) i also have a seperate 2.5x2.5 clone/small veg tent w/ t5 bank
in a garage in pnw, lights on at night, nice cool/cold air to pull in winter medical.
i do not want to add anymore watts. since i am adding a seperate veg light (300w mh already have from an old fish tank light) i dont know if i have enough amps to add anymore, plus i dont want to add much more $ to my elect bill

i have (2) 600w hps air cooled lights, w/ small hoods.
climate controller with co2 (tank) monitor, seperate temp and humidity controls Day/night max/min
(2) 4" squirl cage fans
going to buy a 6" fan?
dehumidifer and occilating fans

max is 12 plants including any in veg over 12 in to stay in my states medical limit w/ 2 cards
want to get max yield from 2 600s, using either 5 or 7 gal pots with Super soil, mainlining, lollypopping, supercropping TGA ace of spades and timewreck.
so which tent do i go with the 4x8 and squeeze in 10 plants with 2 in veg rotating in or spend the extra money and get the 5x10 that will probably hold 12 but less watts/ft???

thanks for reading

The 4x8 is perfect for 2-600s in smallish reflectors. I'd say, unless you are running Blockbuster hoods or bigger, you don't need the 5x10 unless you need the extra room for AC, dehumidifier, etc.

yea, thats what i was thinking...and i can put the extra 150$ toward the 6" and more dehumidification if needed.
