light question
    #10703595 - 07/19/09 11:42 AM (14 years, 7 months ago)

i know i need sumthing around 6500. but does that mean 6500 lumens??? is any kind of bulb that has 6500 good enough or is ther a certain kind i should get? do i only need 1 of these lights? how far away from the box should this be?

THANKSS

No, lumens and color temperature are not the same. A lamp with 6,500 lumens is going to be intense, as light therapy use 10k lumens to be like the sun.

ok, not to say your wrong but i just looked through all the bulbs i have and none of them had a number the k on them. maybe iv never had any of that kind before. all i see on the box is lumens watts and hours

tropical fish and marine fish have a 'k' rating.
Heres a couple,
one being marine,
one for repitle,
one for tropical.

I'm looking at a 10-pack box of 6500K flourescents, it says:
40Watts
2325 Lumens
84 CRI (color rendering index)
6500K (color temperature)

Phillips Brand
ALTO High color rendering

The bulbs themselves don't say anything about color temp.

Dude I use 3 led lights that work great. Light for growing mushrooms is a lot different than light growing marijuana. Marijuana needs light for photosynthesis. The light for mushrooms only tells them which direction to grow in.

If you have new information, why don't you share it with us.

I've seen cubes grow in the dark. So if you are going to say that light is needed for the shrooms to grow, not true.

get compact floros..very low wattage, less energy.  great also for pinning.

Recent experiments(over the last 23 years) have shown the error of that statement in TMC.  Many experiments have shown conclusively that fluorescent lamps in the 6500K range produce better pinsets and healthier, meatier fruits than other forms of light.  Stamets himself does not repeat that 'flash of light' triggers pinning nonsense. In fact, he recommends fluorescent lamps in the 6,500 Kelvin range for 12/12 just as I do. In addition, there's a huge difference in saying something can result in 'pins', and helping to trigger a very nice flush.

Light, and the intensity/frequency of light is extremely important if one is interested in greater than mediocre performance.  Many species, such as agaricus and P cubensis, can pin in the total absence of light.  That doesn't mean light isn't required for best results, especially with light sensitive species such as P cubensis and P ostreatus.

A few milliseconds is all that's needed to trigger pinning BUT that's just to trigger the intensity as well as duration also play a huge roll in just how prolific a pinset can be IME. To reiterate! After the pins have been set light is less of an issue but still has a few benefits to the health of the crop.

That is absolutely incorrect.

In addition, a few milliseconds of light will not trigger pinning.  The fact is, cubensis will pin in total darkness, and that's probably what confused the guys who gave Paul that information.  However, the pinset will be poor and the fruits misshaped.

Contrary to another facet of disinformation being passed around here, mycelium/mushrooms DO get energy from light.  Many people think because mycelium doesn't conduct photosynthesis, that light is only for knowing 'which way is up', which is also incorrect.  The force of gravity is what tells the mushrooms which way is 'up'.  Mushrooms grow towards the light because they're deriving energy from it.

Mushrooms grown in bright, high frequency light will be meatier, have fatter caps, and thicker heavier stems.

Would that be true during colonization? I know the whole darkness during colonization thing is outdated info but why would you need to make sure your bags/ jars that are colonizing dont get much light?

Normal ambient light is irrelevant early in colonization, but there's a LOT of evidence pointing to light exposure during the last week of colonization to speed up the entire fruiting cycle.  Shiitake growers learned this a few decades ago.  By exposing to light during colonization, they get pins sooner and overall flushes are improved.  Mycelium has circadian rhythms, just like humans.  Light and a day/night temperature fluctuation helps to establish this rhythm.

I complelty agree. I have been using bright natural daylight and have seen a great improvement on how fruits have been growing. Ive had some very meaty shrooms come from tubs sitting on my windowsill.

They never grow phat asses and generaly just look much nicer.

I had a few coke bottle fruiting chambers that got forgetten about for a week with minimal lighting and they just didnt grow as nice as anything else that i made the effort to give em bright light. Ive even been giving them a few mintues of direct sunlight aswell.

I watched paul stamets 6 ways mushrooms can save the planet conference and he talked breifly about mushrooms using radiation as a source of energy
