If I have a 100w HPS right now, is it going to make a difference if I add some 26w daytime cfl's? or will the HPS just fade out the cfls?
light...

how many plants? one or two?
I have a 150W HPS running and a pair of 26w/100W CFLS. I do notice when the CFL's get turned off. (gets a bit 'yellower' visually)
I think the spectrum (though not measured) is noticeable.
And it does seem to add to the visible light.
As to weather its noticeable to the plant, I'd look at the veg vs flowering and where you are at and the spectrum of the CFL as to whether its worth it.
just my 2 pence. (your mileage may vary)

There is a debate rolling (and i'm probably losing it
) about if lumens are additive. ie: one CFL =200 lumens, so 10 CFLS = 2000 Lumens some say no, others say yes.I'm gonna call an optical engineer next week and find out. Just gotta get my Q's in order. (also happy to be wrong, I just want the right answer)

Ok.
Take a room with a 100F temp.
Add in a 100F (absolute) heater.
Add three more.
how can 100F be more then 100f?
Is the room soon to be 300F?
Add 10 more. Gonna be 1300f?
10 more.
Going to melt steal now?
nope. 100F is 100F.
If the element can only produce 100F, the room wont go past that. Granted, there base/bias temp, but .........

Actually no you don't.
100F + 100F = 100F (plus/minus a few for the environment) But not much,
Think of it this way.
A candle only produces say (for argument) 100 BTUs;
3 candlles prouduce 300 BTUs ?
But thats how much air or water it can heat.
One candle can boil a cup (16oz) in say 10 minutes. But reach a max of 245F
Two candles can boil a cup (16oz) in 8 minutes, but reach a max of 255F.
It is Not a linear measurement.
I can start my stove on low (but over 212F /100C) and the pot/pan may never boil.
Why?
