First grow 1000w 1 plant SCRoG

I have started a grow journal to document my progess, but i just want to get some input on my inital setup.

I plan on using a veg box for the first 2-4 weeks of my clones life then moving it to my tub where im going to scrog across the whole tub all under a 1000w HPS/MH

Box is almost ready to go, just have 2 pc fans to attach on the top for ventilation.

Not sure if i wanna add 2 fluorescent T5 bulbs to the box or not, not sure if there would be space. Im also considering adding some small CFLs to each corner of the box if i need more light. I currently have 2 200w 5100k bulbs each with cones

Pics attached!

i don't quite understand, where are you mounting this 1k light?

the 1k light will be hung over my bathtub. After 2-4 weeks in the grow box (pictured above), depending on size, i will move 1 of my 2 clones to the tub. Im going to use a screen to cover the tub corner to corner to scrog

plants went into my grow box today
