Question about cfl's

So i was wondering if i could use 1700k soft white cfl's for flowering because i can't seem to find any 2700k lumen ones. would this work? or would it hurt my yield?

alright thanks. another question is. say i get 2 40w 2700k cfl's. and have that as the main 2 bulbs in my y splitter above the plants. i also have 2 other lights comin down from the side. which bulbs should i use in there, the 2 26 w soft whites 1700k. or 2 26 daylights. or 1 of each?

Again you have some confusion going about lumens and color temp. 42 watt soft bulbs just happen to be 2700 lumens and 2700k temp. There are no 1700k color temp cfls.

everyone on here is wrong so far the 1700k is 1700 kelvin which actually is color temp

dont include me in your 'everyone'.

Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, and other fields. The color temperature of a light source is determined by comparing its chromaticity with that of an ideal black-body radiator. The temperature (usually measured in kelvins (K)) at which the heated black-body radiator matches the color of the light source is that source's color temperature; for a black body source, it is directly related to Planck's law and Wien's displacement law.
Higher color temperatures (5000 K or more) are "cool" (green–blue) colors, and lower color temperatures (2700–3000 K) "warm" (yellow–red) colors

Thanks for all the help everyone. i realize now that on packages i was seeing 1700 lumens and was thinking that wasnt the right color spectrum. now i reliaze that it doesnt mean its color temperature 1700. its 2700. so i have 4 26 w soft whites now. should be more then enough light for my space. thanks for all the help

you should get more when you can. how big is your plant? and you'll want 6300 or whatever they make for flowering you'll want as many as you can the more the better for you, your plants, and your yield
but sounds good so far lets see some pix

the 1700 refers to lumens the 2700 is the k sometimes not on the package but it seems most lights are 2700k

Just for your info: 2700k=warm=flowering 6500k=cool=veg
