400 Watt Fluorescent Lights

is 400watts of Fluorescent bulbs enough to grow 3 plant (I have 4 bulbs) there Daylight spectrum bulbs 100 watts each

100w cfl? Or 100w equivalent?

The more important aspect of the matter would be how many Lumens the CFL puts out. 700-800 lumens per sq ft is pretty minimal.

there 26 watt CFL bulbs and they do 1600 lumens per bulb

They should be fine. You should switch to 2700k during flowering.

alright thanks for the help
