Re: Up to date Lighting information [Re: LogicaL Chaos]

I ended up getting 6500K daylight LED work lights. CFL's are kind of getting phased out and LED is becoming much less expensive. They don't throw off heat or have that freaking hum that fluorescents do. I think the quality is a little too harshly white, but they seem to be doing well. I also have  regular incandescent that I leave on for the warmer spectrum.

Seems to me that mushrooms aren't nearly as picky as plants about their light. But they need to have it and the circadian rhythm is important to all living things. Maybe not things that live at the bottom of deep oceans, but top dwelling life forms.

A 6500k cfl provides more light spectrum that the mushrooms use as opposed to a blue led.





imo fungi actually use green-blue spectrum light more too the green i think too but yes 6500k has prob got the most green in it:thumbup:

proof is in the pudding tho, 6500k cfl gives ya nice big caps, while "blue lights" gives you small puny sad looking caps.

i do agree, with some species of fungi, Blue light (470 nm) effectively inhibits fungal growth but cubensis im not certain

12/12 is what you want. They have a circadian rhythm like we do. If it's not perfect you won't hurt them.




this has been said for years but if it is so what time dependant actions does the mycelium have to conform too during each 24hr period?

mycelium does not get jet lag i have tried!! so they cant be entrained by a zeitgeber. fails this criteria

for a circadian rhythm to be endogenous it must persists in conditions without external periodic input. fails this criteria too

also its not temperature compensated thats why shrooms grown cold are smaller and hotter bigger and too hot they grow to fast and split, no temperature compensation?

look here you see the light giving extra thermal energy from the light changes the outcome, they are reacting to external cues not circadian rhythm at all

curiously also you notice that the ones in the light are bent but recurve to be straight before dropping spores, neat trick of cubes to effectivly drop spores.
also the ones not in the light stretch straight up and not to the light, this speaks volumes...

light is not the most important stimuli that decides directional growth in our mushrooms but it plays in a trio with wind and gravity, wind being the most important factor followed closely by light and lastly gravity.
  However if any of the trio are removed from the equation the responsibility shifts to the next most important and remaining stimuli.

BADHAM, EDMOND R

Tropisms in the mushroom Psilocybe cubensis.

Mycologia; Vol. 74 (1982) p 275-?

The growth of the mushroom Psilocybe cubensis was studied in a wind tunnel under controlled conditions of wind velocity, humidity, temperature,and light. The basidiocarp stipe grew into the wind up to the time of spore formation. When rotated with the long axis of the stipe perpendicular to the wind, fruit-bodies grew upright. When spores began to be formed a negative geo-tropic curvature of the stipe occurred but no recurvation occurred in a sporeless mutant.






This experiment shows how you can confuse the mushrooms with these stimuli-

Quote:

as an experiment, you can put the light above and a fan blowing from right to left.  Watch what happens.

In the absence of any wind, the mushrooms grow towards the light.  You can also screw with your mushrooms if you're bored.  Every morning, rotate your trays of pinning/fruiting mushrooms by 90 degrees, and leave them until the next morning, then rotate them an additional 90 degrees.  They'll grow up in a spiral. :smile:

This next experiment shows what happens if wind is removed from the equation, and its left to light and gravity(it chooses light over gavity)-

Quote:



Mushrooms will orient their caps toward light.  They are deriving energy from the light and position themselves to get maximum benefit.

What mushrooms do not need is light to 'tell' them which way to grow.  They'll grow opposite gravity in total darkness.

Here's a picture of penis envy which was turning toward a light source near the floor for exactly this kind of demonstration.
RR






and we all know that if there is a lack of wind and  light they use gravity and grow straight up.!!

now could you please explain how has it been decided that cubensis follow a circadian rhythm and not just
simple responses to daily external cues? like the phototropic response seen around the time of spore drop and re-curvature of stipes in said conditions?

somethings not right to me or am i missing something?

i thought light was mainly used to react with Carotenoids in the cap along with retinals and to aid creating of ATP at the cells possibly along side production of the fungal sex hormone trisporic acid?





:coffee: good morning xD

I totally agree on this. Tropisms are what dictates mushroom growth and when one of them are gone or too intense, it will fall onto another.

But when all of them are ideal you will be getting the best fruits you can possibly get.

As for light, i dont use a light bulb, i use sunlight. I position my tubs so they get hit with direct sunlight through the window while the sun is setting. In the winter they get far less light than the summer.



These are all examples of insufficient lighting from my window during winter. Only about 8 hours a day of light overall and about an hour of it is direct light. See how spindly the stems and some caps are, as well as bending towards the source.. These grows would benefit from a secondary light source.



These are from the summer time where they get 14+ hours of light and at least 3 hours of it is direct. This is the same window/room being used. The only difference is they bend when they arent getting enough light, once they get enough, it uses gravity or wind as the determining factor. This is how I determine if there is enough light.



Also ive never done the 24 hours of light experiment, but supposedly RR says it was hindering growth more than the 12/12.

right on mad:thumbup:

glad someone thinks the same.

edit:
coincidentally the tubs you have in sunlight in the winter would have a more red spectrum light than the ones in summer as the sun stays lower and the shorter wavelengths are more strongly affected by Rayleigh scattering, and red light is considered inhibitory and this compounds with the lack of light

I have daylight bulbs in the ceiling light, and a lamp with one as well close to my tubs. They also get some direct sunlight in the evenings. Works for me.

Not all sunlight passes through glass windows. Not sure how important this is. We need, for instance, to get at least 10 minutes of sunlight in our eyes daily, but that particular sort of sunlight we are in need of gets filtered out by glass windows (also glasses).

Not sure how much this affects mushrooms.
