I Have a Filing cabinet with dimensions of 4 X 2.5 x 2 I have never grown pot before but im thinking of making this into a little grow room as of right now I have 1 computer fan (will that be enough) also what would you guys recommend for lighting
depends what plant you are growing. And one computer fan is not enough, need probably atleast 3-4. For plants I would use Low Rider/Snow Rider/Diesel Ryder/ and such. They dont grow too tall
