a purple cfl ? what the hell is that ? what light spectrum is it ? you need something in 6400k for it to be any good in vegging .

I think you have something confused. purple cfls? neva heard of such and if they are real then I am quite sure that will not work for growing MJ.

if ther is such a thing it would be just like a 4ft black light.
If you look about half way down this page nltes UK - Home it shows purple cfls, colour temperature is suppose to be 25000k and it shows the spectral power distribution to be good in both red and blue. Not sure how that all works but there you go!

2500k is to low

Dude why you are trying to spend all that on Cfls?? Man get a 400w from insidesun.com for $140 buck shipped to your door.

If its anything like a blacklight than it will not work.

They can not.
Blacklights do not produce the correct spectrum of light to grow plants.
The only lights that currently produce the required color spectrum of light to grow plants are the following;
Suitable for Growing:
Flourescent (Tube shaped)
Compact Fluorescent
(a flourescent tube with ballast included that screws into regular light fixture)
Metal Halide (MH) Best for Vegetative growth, but it doesn't contain all of the spectrum needed later during flowering for truly outstanding buds. the light shines a blueish/white color
High Pressure Sodium (HPS) Best for Flowering. Ok for Vegetative. shines a yellow/orange color. All can be purchased at your local home/lumber store.
Not suitable for growing:
Blacklight type flourescent lights.
ANY incandescent lamp
(if it screws into a regular lamp, it won't produce worthwhile buds). Exception, compact flouro mentioned above)
Halogen
Mercury Vapor

let me make an exemption mogie. you can veg with Mercury. it is what people were using before MH came along. since the introduction of Metal Halides, the MV has all but drop off the planet.
It is not a blacklight
It is a PUR light - called purple because it is strong in both red and blue parts of the spectrum, blue and red makes purple.
Apparently ordinary fluros emit 100% PAR (Photosynthetically Active Radiation) but PUR lights concentrate on Photosynthetically Useful Radiation (PUR). According to the source 'PURple is generally accepted by the experienced as “the best" fluorescent plant light'. (source: PURple for the highest quality)
This web site is well worth a look at, it gives some good description on this subject with links to various articles. There is an article there on new lighting technology photoponics, based on this PUR technology - sulphur plasma lamps (the only true full-spectrum lamp) which I must say sound absolutely amazing, although not hugely available or affordable. They go on to explain the sulphur microwave lamp currently only supplied to research centres and nasa this lamps efficiency is so good that a 1000w is equal to a 2500w HID in terms of photoponic output and apparently you can change your plants to a 20 hour day cycle and flower in 20% less time with the same or greater yield with less energy - to top all of this the bulb is said to only need changing every seven years.

super interesting.... some one (i would love too one day) try incorparating this type of light with an aeroponic, excuse me ahem, combine this new technology with a Maero system for rapid growrthh... new experiment ??

my first gow in soil
so i thought I would try the purple cfl complete kit, no nothing about light spectrums and just want to know if it will work, have done all homework on grow space / ventilation / tempreture,humidity / seeds/ germination / growing medium etc.
replies much appreciated and thanks for a good site. Regards, S
