Led/setup question from a 3 time noob

I'm new to this board, new to vertical growing, & new to LED lighting. I just have a quick question for some opinions or suggestions.

Equipment:
Probio Grow Cube (48 or 64)

Hydrogrow 420x (1 or 2)

1. Will (2) 420x be able to mimic the suggested 2K watts for 4-5 lbs. yield as advertised? (& seen here... https://www.youtube.com/watch?v=MOwp1eb9odQ&feature=plcp )

The cube and the vertical LED fixture should make an awesome setup. I think you're looking at the right stuff. What's the size of your grow area? Ventilation?

I have a 10'x10' area to work in. I'm still prepping, haven't really got to the ventilation yet.
