ok so i hear some people change the light when flowering and some dont heres my question im in the midst of my first grow everything is going great but im doing it very inexspensively so heres my question will the light im using to veg also flower my plant when i switch to 12/12

What Kind of light is it? Most people switch from mh light for veg to hps bulb for flowering, but it is the light cycle that makes a plant flower not the type of bulb. So as long as you switch to 12/12 it will start flowering.

honestly im not gonns lie i dunno what kind of bulb it is it was in a lamp at my house and i turned the lamp into a light fixture for my first grow i will indeed invest in better equip for grow 2 but for now its working fine i was just wondering if this same bulb will work for flowering o thanks for the info

Well..before folks lay into you..let me point out the growfaq lighting section.GROWFAQ Now, Like you, I once thought any lighting would do. It won't at the bare minimum you must use compact flourescent bulbs. If you want any yield at all, your plant needs the proper lighting first.

dont know what light u have but u say its a veg light. veg light have a blue spectrum (normally 6400k). the blue light that is absorbed by the plant helps it veg. once u turn to flowering stage u should really change the color spectrum of ur lights to red, 2700k.

however i am still a noob myself. i would guess that the plant would still grow, just not as fast and turn out as strong or produce buds as big.

my 2 cents

Yes I have to disagree with the blues for veg and reds to flowering.
That is so generalized.

u have to disagree with it? errm, i dont see how. 6400k for veg, 2700k for flowering.. thats the way to do it. spesh for CFL's.
