Flowering with CFL's

mean.green said:

the sun generates on average about 10,000 lumens per sq ft.

In a nutshell…

Lumens per square foot:

Minimum amount of lighting needed is around 2000 lumens per square foot.
(Two – 23 watt CFL’s, per square foot*)

Mid range is around 5000 lumens per square foot.
(Three – 23 watt CFL’s, per square foot*)

Optimal is 7000-7500, or higher, lumens per square foot.
(Five – 23 watt CFL’s, per square foot*)

Hello All, I am currently flowering with 1 23w soft white 2700k and 1 60 w 6500k, 1 85 soft white 5500k and about to add another cool white 2200k 45w. Is this enough or do I need more 2700k lights ?
I know that using a HPS but dont have that yet. So using what I have at the moment.

Thanks for any input

You have a 2200k cool white? Interesting! You could flower with that, but that's obviously not optimal. I would go buy two 4 packs of 23w 2700k cfls from a home improvement store with some y-splitters and lamp sockets.
