If you want more light for flowering (recommended) when you change your CFL's to a different spectrum why not get a higher wattage? That is if you can get better ventilation.

I have roughly a 4' square area 8 am growing in. its acually 3.36' squared. I have 8 compact spirals in a homemade hood. these are 23 watt bulbs that produce 1,600 lumens each. So they state anyways. This is a total of 16,000 lumens being produced. Not including my side lighting. Which are 17 watt floros that have a 75 watt equivalent. Not to sure on how many lumens there Rating: 5
