so do I use a 5000k bulb or a 10000k bulb?

RR, you said that higher frequency light above a color temperature of 5,000 Kelvin will generate far more pins than a 'red' source of light such as incandescent lamps."
So with this in mind, do I use my 5000k compact flourecent or my 10000k compact flourecent?

Any metal halide will do, since its spectrum is on the blue side...

I was curious to know which compact flourecent would work better not an HID. But thanx for the try.

OK maybe I should clarify. I HAVE a 5000k and 10000k compact flourecent. Out of these two ONLY, which would work best?
Thanx for the help shroomies!

....5000k.
10000k seems like it would be too...bright/penetrating
but then again, i do remember reading stuff about shrooms and more blue light. who knows, try both. im sure it wont hurt them.

Hi Mate. Seems you're getting some advice from poorly informed people. The 5000 vs 10000 K bulb has nothing whatsoever to do with canopy penetration, instead the K represents the "color temp" of the bulb expressed in degrees Kelvin. It's really an arbitrary rating to botincal folk, who prefer to use PAR (Photosynthetically Active Radiation)to measure spectral output. Anyways, use the 10000, its a bluer color than the 5000, which is more red. If RR said red light ain't what you want, definitly use the 10,000. Good luck mate!

Thanx that makes since. I was curious to know though that if you can reach a point where the light is to blue and not enough red. I have a super actinic bulb. That is super blue, would that be best?

Yah that'll work perfect. You can't really get too much blue light since blue light is apparently the "light trigger" that aids in the fruiting process for fungi. Red light has a number of functions however, many of them have more to do with inducing fruiting in plants and photosynthetically active plants who need the red light to signal the end of summer (vegetative growth) and beginning of fall (reproductive/fruiting phase). Hope this helps!

in response to brainiac's misinformed post, heres something RR just posted in the "12/12" thread. I've read this as well over at mycotopia.
Below text is a partial quote from RR. Read and learn:
Light is also NOT just to establish the direction the fruits grow. In fact, air currents have a greater effect on direction of growth than light. If you doubt this, place a fan on your crop and watch.
A few seconds of light per day will NOT help to generate a good pinset. In fact, light is a secondary pinning trigger, but an important one. The difference between three or four pins, and hundreds of pins on a substrate can be directly correlated to the length, intensity, and frequency of the light applied, provided the primary pinning triggers have been fulfilled.
The light needs to be intense enough to penetrate 1/2" into the substrate. Not all pins form on the surface. Many originate from deeper in the substrate or casing layer.

Metal Halide? We're growing shrooms, not weed! LOL! Oh what the hell do I know.... I just think that Metal halide requires ballasts and produces lots of Heat. Too expensive and too hot IMO.

wow LOL
I use a like 7k light bulb florescent, random ass one kinda yellow looking when on.
And I def get more fungal fun than a lot of you.

lighting isn't as important to trigger pins as FAE is.
I thinks its a waste to got out and waste shitloads of money on lights which emit lots of light. a few blue-tinted light-bulbs is, in my experience/opinion, just fine for triggering pinning.
but hey, everyone has different opinions on this matter, so do whatever makes you happy

My experiments show a color temperature of 6,000K to 7,500K seems to generate the best pinsets across a wide range of species.
Intensity is also a factor, and you can get great pinsets with metal halide, even though its output is still in the 'red' range of around 4,000K. However, a cost effective/low heat solution is natural daylight fluorescent which comes with a color temperature of 6,500 to 7,500. Sorry, I haven't tried the 10,000K tubes, but that's getting pretty close to the uv spectrum, and we know that tends to cause problems, especially long term. Good luck to all. Don't be afraid to experiment. RR

Interesting, I wasn't aware that the type of bulb made that much of a difference. I use a regular "off white" off the shelf 12" light bar on the GH and havn't had any issues yet. Might try a "natural daylight" bulb on the second GH next grow.

Well, heat isn't usually an issue since most people (not me) use some kind of heater system to keep their FC at 86 or close, which I assume is about 12-15 degrees warmer than most peeps keeps their house.
So maybe HID is not the best way to go, but it does kill 2 birds with one stone, if your FC is in a room cooler than ideal.
Since cubies DO NOT need a temp drop, heat is your friend.
Try one cloned casing at room temp and another at 86, you will see what I mean.
HID is intense enough to penetrate, common household bulbs are not, typically...

I plan to try 10 blue LED´s in a FC. Not a lot of "power" but it sure is blue enough.
What do u guys think, will it work???
