light questions

[evan46290]

I have a few question about lighting for an indoor grow. it will be a 4 sqft grow room. as of now i have 153watts of compact fluoros producin about 9k lumen. That works out to be 38 watts per sqft. Is this enough light to produce a good yield? I used thsi setup with crappy mids and it worked but was a small yield with a 3 feet plant, let alone it was very stressed early on and was not grown as well , and got about 10 gramss dry. Are seed genetics that important on yield? Or would getting an hps or mh bulb make that much of a difference in yield? thanks for help in advance
