? 480w 2.6 umol/j

So does anyone have some example grow pictures they can share that was done with 480w qb in a 4x4

Ur asking a lot lol. Most people try and get about 700ppfd average across canopy, that looks something like this.

I would just search for Mars Hydro FC 4800 grow journals and reviews, I've seen quite a few around the different forums, it's a common light with that wattage.

ok so i mean my question bouils down to i dont have alot of money but im gona be buyin a light or to my goal is to light a 4x8
i have 2 offers to 1st is 2 480w q bs for 360 2nd is 1 720 w for 398
now i could buy 1 720 and use 315 cmh on the other 4x4 how ever
why not just get the 2 480w for the priice of 1 light is the 720 realy going to do that much more

Depending on the brand it might be worth getting the 720 and buying another one once you’ve got abit more spare cash. But 2 480s are gonna be fine in a 4x8 I would imagine (depending on brand). It is on the low side of what would be considered ideal but would deffo work.

I use bar style lights 480w in a 4x4. I still consider myself a rookie, so know it can definitely look better.

2 4x4 bar lights like these, any sort of Spydr knockoff, might be the easiest option to get an even canopy.
