Apollo 4x4

Just order Apollo 4x4x8 tent. Ive been torn between 600w hid and 1000w hid. More specially the iPower brand. Was going initially with 600w but on Amazon the 1000w is the same price as the 1000w (may be cheaper not sure). But after purchasing the tent i realized the tent is more specifically 48x48. Will those extra 8inches be significant enough to get 1000w? Or keep 600w? Will be growing 5 auto flowers in 5gal grow bags.

I'm lost, did you think there was 10 inches in a foot? 4ft x 4ft x 8ft or 48x48x96. I say the 1000w and dim it if you want. Easy as that.

Just grab the 1000w if you can handle the heat in the summer, or need it this winter.

Go one better and buy a 1000w digital dimmable and make sure its one that dims to 600w rather than 75%
It wont cost you much more. Plus you can then run 600w MH and if your environment allows crank up to 1000w HPS when its time to flower.

Google ballast comparison, there is some serious variation in output from one cheap brand to another.
