Also are you vegging them with 2700k cfl bc they looked like they were yellow which is on the red side of the spectrum which is better for flowering, I think you should have 6500K which is for vegging.

I'm confused now, I was told to use the cfl's that I'm using for veg and ad some daylights come flowering.

I'm going to get one of those meters ASAP because I think I'm over watering. again thanks for the information.

Correlated Color Temperature(CCT)

The first factor in choosing a color of lamp is to determine whether you need a warm or cool light source. The CCT, expressed in Kelvin degrees, relates to actual thermal temperature. If you've ever seen a piece of metal being heated, you know that as the metal gets hotter, it's color changes. The CCT rating of HID and flourescent light sources indicate how warm or cool the light source is. For instance a lamp with a CCT of 2700 Kelvin is considered warm; with a CCT of 4200 Kelvin is considered neutral; and one of 6000 Kelvin is considered cool.

I got this from the grow faq and as you can see that 2700k is considered warm, which is best for flowering, hence why hps give off a yellow light, like the cfl you are using. And 6000k is cool or on the blue side of the spectrum (more of a white light), which is better for vegging. Im not saying that they are going to kill your plants, just figured that i would mention it to help you out a bit..
And get that moister meter they are well worth it...
good luck with the growing

heres a pic of my mother i vegged her with a 6500K cfl that was only 24watts with a cheap reflector from walmart

Thanks for all the information but I'm still confused, could you possibly show me some pictures as to what light for what stage? please see attached files, I'm using softwhite (at least I think?) witch I was inform was best for vegetation and warm or daylight is best for flowering.

I plan to start flowering soon, since the lights that I'm using are best for flowering should I just keep the same lights and get the others for next round of vegetation?

just read the packaging or the bulb itsself, and see if it says the color temperature, 2700k, 6500k ect.

I'm sorry but there are no color temps on the cfl packaging or bulbs, however on the standard flos it reads "color temp: 4100" are you referring to the flos, are they not good for vegetation? also I need help determining what type cfl bulbs are best for flowering.

Daylights are best for veg and warm white for flowering i think

so for veg you want to see 4700K or more, and for flowering 2700k
Im using cfl's right now, but i cant get hold of any daylights so im just using cool whites and a few warm whites for veg, its not to bad as long as you keep the light about a inch away from the plant to try and prevent to much stretching, my plants are looking ok so far, check out my log, ill be adding more pictures soon

I'm using soft whites for veg and I was told to use daylights for flowering (I'm sooo freakin confused) I'm about ready to start flowering but need to make sure of a few things before I do, if all else fails I will just put half and half I guess.

Transplant And Use New Medium. Also Look Into A Shop Light With 4 Ft. Bulbs At Least.. I Picked Up A Hydro Farm Brand 600 Watt Hps With Digital Ballast And Bulb And Reflector Hood On Ebay For $150.00. It Would Be A Very Smart Investment And Also The Electric Bill Only Went Up .22 Cents A Day. So About $6.00 A Month.

Thanks caligrown for the input however i'm now 46 days into flowering with a ton of cfl's almost the equivalent to a 400w hps, I do plan on getting an hps though for future grows, if interested check out my current grow journal...
