The rule of thumb is at least 50 watts per foot with hids. Leds are more efficient but dont have good par reach so basically the leds above are the ones that will powering whatever's below them but wont have much benefit to the plants on the other side of the area. So I'd think the rule would be about the same. 50 watts per foot on your panel totaling in about 600 watts of led.

thanks for all the advice what would be the best colors or just do a full spectrum evenly(equal # of led's per ''color''/wavelength) ???thanks

Well Par absorption of chlorophyll a and b both peak at about 440nm blue and 670nm red, give and take 10nm. Which isn't the only thing to consider but is important. I've read studies where they say using a bit of mid white(green) was crucial in healthy plants . If I was making one I think I would go about 60-70%red 10%white and 20-30%blue, just use it for flowering and veg with t5s or cfls or something. or make a slightly smaller one for veg.
