I'd get the bigger cfls, as they have more lumens and better penetration. You will need a fair few cfl's for that area.
amstron Reviewed by amstron on . Amount of CFL vs Higher Wattage. Is it worth it to drop the extra money on the big CFLS (105-125 watt 30-50$ a light) Or use multiple low wattage? What do you guys with experience think, because I'm considering using all CFLs to save money but still would like to attempt a sea of green grow in a 4X4 organic soil bed (for 16 clone SOG). Rating: 5
