I have all LED's, but HID and LED is a hard combo to beat. Using the lighting you have would be barely citting it i would guess. However, you could use a little more light in there. I think a 400 or 600 would be best and if it was indeed too much light you could perhaps start using some co2 to really see a difference. I have a 4x4 and ill run atleast 780w in flwr so the fact u have double the space and less watts does scare me just a lil, but my grow isnt 100% efficient ya know?
With LED's the main weakness is light penetration and coverage. They dont need to be right up on the plant but the light doesnt seem to really pack a punch over longer distances. The 3w chipsets are supposed to address this however it still doesnt match that of hid and hid also offer a bit of light in other usable spectrums .
SO: you could probably get by with out it, but if you want some awesome results i would suggest adding atleast that 400w in the middle to get that rockstar qual.
