Setting Up My New Grow Tent (NEED HELP!!!)

What Pros said, and two more things.

Depending on how large your plants are when you start flowering, you will probably only have room for four buckets not five. Over crowding reduces air flow....reduced air flow increases chances of bud rot.

And I would darken those buckets. Spray painting the outsides will do the trick. Roots don't like light, and we don't want algae, etc growing in your substrate - it stinks and takes nutes from the plants.

Other than that, it looks good.

Looks good to me... I wish you the best of luck... Just don't forget to raise your light as high as it can go. Measure the available vertical space, do NOT go by the dimensions of the tent, thats where I messed up. Remember that plants will double, sometimes triple in size when flipped to 12-12, so keep that and your available vertical space in mind...
and I'd start with just one or two plants till you really get the hang of it. more plants can mean more problems, not to mention the over-crowding issue.
