C99 Future Setup

Hi. I've been planning to grow 2 Cinderella 99 plants. This will be my first grow. I wonder if this setup will do:

2.5ft x 2ft x 3ft growbox
300w LED growlight
2 exhaust and 2 intake PC fans
1 small oscillating fan

I heard that C99 grows short and bushy so I want the height to be short as possible for a 2 plant setup.

You really need more than 3' height. At least 5'. Good luck. -granger
