are lites beter then a cloudy day

ok so i brought these 2 ladies in from outdoors cause im in canada and battling early frost,mold,and lots of rain...i put them in my sun porch cause it same as being outside without the rain and cold as the sun porch is all windows....
My question is ,,i have 4-4ft florecsent lights i use for cloning,will these lights be better then i cloudy day in the sun porch..

You should post this in outdoor growing

I figured since it was a indoor light question i mite have better results here...guess not eh...no biggie,was a spur of the moment decision and they seem to be doin great so far...
