Its usually around 30-35 watts per square foot for top quality LEDs and around 40-50 for cheapo lights.
Not sure if your 9x9 is feet or meters, but if feet then it would be 9 x 9 x 30 to 50 = 2430 to 4050 watts total.
Hope that helps some.
Best of luck and happy growing. :P

So its 9x9 ft.
Can u guys help clarify how wattage per square ft and PDF map correlate to each other.
Because i see a lot of lights with high wattage but outside dead center the intensity drops off significantly.

I'm not sure where you live, but maybe look into building your own lights....LED strips.
It can help reduce costs...helps keep light coverage more stable everywhere...lots of benefits, but no warranty beyond parts warranty.
I've built 2 sets myself...simple basic ones with 2 foot strips that run 320+ watts each 16 strips, but put enough strips together and your set. :)

Ok i get the 25 watts per square.

What about drivers
What about diodes
What about a even spread of light intensity?
Sometimes i noticed my light seem to be so much weaker in certain places under the light how do i rectify that?

They say a minimum of 25 watts psf. So a 2x2 tent =4 sq. ft. 4x25=100.

I ran a single Spider Farmer SF-1000 (96 watts) in a 2x2x5 5 plants in 2 gallon pots last year to try it out and it worked great. Problem was tent height. Even though I flowered at 10" they ended up 8" from the LED after stretch which was too close and caused foxtailing. And that was after supercropping a time or two.

Total yield of a Blueberry strain was 88.36 grams plus 2 oz of trim.
