The wattage per sq ft opinion depends on who you are talking to. I personally go with 50 watts per sq ft for veg and 70 watts per sq ft for flowering and it works perfect for me.

Your light looks looks great for a start buddy! I also like the design of the hood, it could be very easily modified for air cooling if you decide to go that route which i would suggest. Good luck and safe growing!
