and not is only shown on lights specifically made for growing plants all the kind of lights had a kelvin degrees even a candle

Yes, you seem to understand the kelvin. But what I am saying is that only grow lights, specifically made for growing are labeled with a kelvin color temperature rating. Yes, I too know that all light sources have a kelvin color temperature reading of some sort. You see, different types of grow lights heat up to different color temperatures.

here is kelvin table

From The Cannabis Bible by Greg Green:

CTT in Kelvin (K)/ Light Color/ Effect/

5000 to 8000/ Deep blue/ Encourages excellent leaf
and stem growth.

4000 to 5000 / Light blue/ Encourages good leaf and
stem growth.

4000/ Neutral white/ Promotes normal growth.


3700 to 4000/ Warm neutral/ Promtes rapid growth.

3000 to 37000/ Warmer yellow neutral/ Highly active
photosynthesis for all
stages of growth.

1500 to 3000/ Hot orange or red/ Promotes flowering.

Thanks sensi and desk, you've given me stuff to think about when i go off to find some flowering light.

keep ya posted!

Bob.

No prob.

good day,

The only grow lights ive been using are fluros, dont sweat buying HPS unless you have the money, but the daylight compact fluros are working killer for me...

if moneys tight....fluros work....more the better...add UV to your spectrum during flowering to induce more crystals( a plants natural defense from uv...) and attain better results...

....BUT... it is hard fact that if you experiment with multiple light sources indoors...
-quantity and quality can only be gained by using metal halide, high powered sodium(HPS), and mercury vapor (very high UV, sold commonly as security lights) indepedently or in some combination...
MH veg , HPS flower
HPS bolth cycles
CFL or fluors veg , HPS flower
HPS and MV lighting in combination during flowering can be VERY effective in combination producing large dense heavily crystalized budds...................

Ok thats my 2 cents on that...peace

Well, after cutting down 2 males and a hermie... i'm down to one big female.

here's some updated photo's, she's almost 2 weeks into flowering.. she should be exploding soon.

enjoy!

Quite nice picks BobBong. I was wondering what kind of power CFL'S would u need for a few plants? like how much wattage? i've finnaly understood the kelvin lighting on the bulbs, so ill need something beetween 5k-8k kelvin for growth, starting flowering 1.5k-3k right? how much did all that lighting cost you bob? ( The incandescents, the spek lights, and the cfls i mean) cheers, thx

bob, do you have a fan in your cab ( i didn't notice in the pics)? what are the dimensions? Nice little setup and good looking plants!
How's it lookin now?
