I'm kinda thinking intense direct lighting for a great pinset then indirect less intense lighting for fruiting but lighting kept on the same 12 on 12 off cycle throught the whole process.




This seems like a good experiment to do

I'm always amused at the amount of 'controversy' this subject gets.
It's worth noting that for any comparison between multiple subs to be perfectly valid they need to be the same monostrain.

This is a common misconception based on perceived effects.
If you take a look at timelapse shots of growth you will never be able to tell when in the cycle you are.
As mushrooms grow their growth rate increases but doesn't step as you would expect if they grew more during half the cycle.

Is the fucking melanin dude  :getstoned: lol.

Pigment Power

Melanin is widespread in nature and has long been known to provide protection from ultraviolet radiation, which in high exposures can cause skin cancer.

The pigment is present in most fungi and also accounts for skin color in humans.

"Melanin is pretty amazing stuff," said Duke's Vilgalys. "It's not surprising that many fungi have figured out how to use it for protection and possibly as a means to harvest [energy]."

John Dighton is a fungi specialist at Rutgers University in Camden, New Jersey, who has worked with a team of Ukrainian scientists studying fungi at Chernobyl.

He said the findings "confirm some of the thoughts we have been having for a few years."

"Fungi that have been previously exposed to ionizing radiation have a propensity to direct their growth towards sources [of the radiation]," Dighton said.

"We have suspected that cell-wall pigments, such as melanin, may be involved."

For now, lead author Dadachova said, the actual mechanism by which melanin captures and transforms high-energy radiation remains a mystery—though that's to be expected.

"For photosynthesis, it took decades for the mechanism to be understood."

Despite RR's claim to the contrary I have seen little evidence to support faster growth at night. I do believe tho that a heathy circadian rhythm does allow for a better maturation overall. Certainly my fruits that grew with a timed cycle grew better than the ones where I was relying on remembering to turn the light off at night and on in the morning.

I'd assume the gourmet medicinal industry has done enough tests with lighting.
They all seem to use floro's.

lightless ones searching for light, grow longer. Common trait. (theory)




Quote:

Perhaps rather than feeding on it (which we know they don't) the light is a trigger... but for what exactly? Pinning? sporulation? fruit development? other?





sort of what i was saying with-
wowimflabbergasted- i wonder if the increase of light intensity was a signal the mushrooms and tells them they would have grown above the height of say grass in the wild and at a good height to open caps and release spores into now available air currents.( maybe they know how high they are by increasing intensity of light as they get taller and when reaches a certain intensity triggers sporulation?)

if we look at WOWs pic only the ones in the bright light are bent over- maybe thats harking back to what hamloaf said about light and the side of fruit using it- so them one are bending in the light to show off there sides?




what i would like to see is if after the fruits are activly growing if we increase light intensity can we force the caps to open? thus proving my above thesis.

if this happens, i would guess it is light intensity raising that triggers the slow/reduction of polyol mannitols in the mushrooms (mannitols are responsible for the flush of water entering the fruit and causes cell expansion and upward growth.) and switches function to open caps to sporelate.

it makes sense the mushroom would have evloved to be able to release its spore in the most convienent/successful way and mushrooms that did it this way would pass on their genes to do it.
the mushroom would be using light intensity levels to tell it had grown up enough to sporeulate and light to make sure the cap faces correctly to aid in air currents spreading spores.:smile:

does this not go along way to explain- thinner longer shrooms in lower light(not reaching light trigger), caps opening prematurly in high light., mushrooms growing toward light and caps mostly always facing light source?

im not saying the mushrooms fully rely on light levels to tell them when to open caps but maybe if the mushrooms never reached the light levels required to trigger opening caps, when they reach the natural limit of upward growth they open caps and sporelate anyway even if they light levels are wrong just as a means of survival.:smile:

as i said before an easy test would half way through a grow and shroom have half grown move your lights alot closer and see if it forces the caps to open. it this happen and is repetable over and over then the above thesis is along the right tracks :smile:

EDIT: the benefits to be gained by finding out would be able to set the distance of light so that on average most shrooms will grow to a certain height range before recieving high lux levels and triggering the opening caps, grow to a certain density range of fruit(by controlling elongation of cells) and time lengh of fruiting process itself!!
quite rewarding really, to dial in the fruiting process :smile:

seems violets tests/experiments points to this conclusion, as does the information spitballjedi posted

and RRs experiment of ties in with it aswell-http://www.shroomery.org/forums/showflat.php/Number/14311145#14311145

Then are any of you guys using HPS.There is no debate thats it has the best range of lumens to replicate nature.
Im still in the old school mind set that i dont need lights to grow mushrooms.But if you guys are telling me i DO need lights then there is no doubt in my mind HPS or atleast MH would be better then florescent.
how much does it play a factor beyond Genetics/moisture content /RH and /FAE.
would a 1000 watt light be better then a 500??



When utilizing light for mushroom growth, it's best not to exceed 10,000 lux.  Mushrooms are not like our plant brethren.  Mushrooms do not require full sunlight.  Mushroooms grow best in shaded areas. 

As mentioned above as well, HPS is about the 2700K range and is no where near the optimal spectrum for mushroom growth.  MH would be more suitable for mushroom growth, because it's closer to the correct spectrum, but I wouldn't use High Intensity Discharge lights to grow mushrooms with.  That's too intense.  Another major problem with using HID's is the heat load HID's put on a room, and the amount of ventilation required to evacuate the excess heat favors an arid climate unfavorable for the formation of mushroom fruit bodies. 

Light plays the least important environmental factor of the 4 major environmental fruiting conditions.  In my opinion though, lighting of your mushroom growing room should not be over looked.  In my experience, a proper lighting schedule (time of exposure & spectrum of light) produces a far superior fruit, than .

I have also noticed photo-tropic responses in fruiting mushroom bodies before to where a room was mediocrity light with supplemental florescent lighting in the 6500K range, windows were allowed to be left without their shades on so ambient light could enter the room unhindered.  The fruits from the substrates/fruiting chambers that were placed/stacked next to the unshaded windows grew towards the window. 

Mushrooms don't need light to complete their reproductive cycle, and is one of the, if not THEE major reason for the fungus survival on this planet, and being the oldest living organism on this planet today that's known to mankind.  Mushrooms do gain, and are capable of utilizing energy from light for growth just like all living things on this planet genetically predisposed to co-exist with the sun though. 

Furthermore, I would like to add that mushroom fruits DO NOT absorb the light they utilize from the tops of their canopies like plants do.  No.  Mushroom fruit bodies absorb 90% of the light they use from the sides of their bodies.  Electric, artificial lighting supplementation utilized for the formation of mushroom fruit bodies should be hung from the sides of the room.

Wow i have a lux meter, and mushrooms grows in nature at a nice shade under some trees at 500 lux average. 10000 is too much, even 1000 is too much.

New lights out now  a days plasma' lights "The light emitting plasma technology produces a spectrum that is the closest to sunshine that you can find in a light source"
i here what you are all saying about HID lighting, but on a large scale room it might be the best.
I couldn't justify the cost, im just throwing the information out
If its to much light you can always use shade clothes.

Hmmm good point.. on a open field cloudy day there is easily 15000 lux units, i just check it. Then i don't know why on paul stamets fruiting parameters books and other sources like in shroomery cubes fruiting parametes always point out that they should be grown at 500 lux average.

would love you to use that light meter in a monotub lit by cfls to find out the average lux levels at surface of the substrate is?

i have said a few times i think it will be surprisingly low :smile:
