I have two 40 watt natural sunlight fluoro's for flowering. Should I look for something higher wattage? Money is an issue also look at this http://www.overgrow.com/edge/showthread.php?t=21575. Maybe I could double my set up and buy another light fixture and two more 40 watt bulbs. It was only 26 bucks and I only want to grow 2-3 ladies at a time.
