Lighting Experiments? 1

Anyone ever experimented with different lighting conditions? For example, 12 hrs of light vs 8hrs of light vs 24 hrs of light? Or maybe even tried sunlight with extra lighting for "maximum" lighting?

I have tried light stressing a few times with little to show for it. I got the idea from an old Dotchi no Ryori cooking show where some mycologist was producing a special variety of portabellos by light stressing them for a few days then cutting off all light and restricting FAE for a day. It produced a specific concentration of flavor that was famous at the time(2004?). I tried something similar with cubes(250Watt 6500k CFL @12 inches away) and it just made them taste stronger haha.
Elfstone's old posts where he claims that 453nm blue LED light is the optimal spectrum for mexicana has proven to be true for me. Whenever I use 453nm with mexicanas they stand up strait with none of the common curly stipe seen with the species.
My current setup is 100% about exotics and a big part of my strategy is to offer them everything they would possibly encounter in the wild. So, as part of this strategy I have made a light source that is a tad closer to sunlight. The setup is a 40W 2600k CFL, 40W 6500k CFL, 26W 453nm Reefbar LED all next to eachother and aimed at the room as a single light source. So far everything seems to be reacting well, even the commonly super curly galindoli's are growing more strait and upright.
As for potency difference, I would have no empirical way to test that and I do this stuff for the challenge anyways.

For species that are seasonal, my hunch is that light cycle plays a role in fruitbody initiation. There are a lot of factors at play: increased rainfall, decreased temperature, increased debris, etc. Decreased hours of daylight is also a common factor, and I imagine that many species (but certainly not all) respond to specific light/dark cycles.
Most people who are cultivating actives are focused on Psilocybe cubensis, which is probably not as heavily dependent on light cycle as it's a tropical species. I'm trying out 10/14 for some of the seasonal species that I'm working with. I'll have to do 12/12 after this batch has fruited to compare results as I only have one growing area right now.

Very cool! Stronger tasting cubes 
Very interesting lighting set-up u have for those Mexicanas. Next level stuff 
By seasonal shrooms, do u mean like Ps cyans? I bet that species would benefit from a varied light cycle

Yup! A lot of active woodlovers fall into that category. I agree, I imagine they'd benefit from some sort of modified (i.e., non 12/12) light cycle at the fruiting stage, but as far as I can tell it's still an open question.

I dont have a reference on hand right now (maybe later or something)
but i did read that they found that there is a "significant" oscillation between psilocin vs psilocybin ratio linked to light cycle.
Seeing as its standard to destroy a lot of the psilocin upon drying unless you are freeze-drying, it can very well mean its best to keep the light permanently on or off the couple days before harvest.
But stupid me, dont even remember whether thats light or dark. Surely you can google the data i'm inferring this from for yourself.

As far as I know most mushrooms react to blue light, bordering a bit on *some UV and *some green and responding less to other colors. However there are species which react to red light.
I guess there has been some convergent evolution happening too and it probably depends on the habitat and how sunlight scatters and what wavelengths are left the most which i think tends to be blue.
6500K is pretty cold light so lots of blue.
I bought a very nice blue LED tube about 2 years ago because it would be flashy (and i think it increases cordycepin concentrations in C. militaris?) however looking at that light when i work near it makes me pretty loopy haha.
Yea pretty interesting:
Quote:
there were significant differences in cordycepin contents, adenosine contents, and mycelium growth caused by light wavelengths: cordycepin, blue light > pink light > daylight, darkness, red light; adenosine, red light > pink light, darkness, daylight, blue light; and mycelium growth, red light > pink light, darkness, daylight > blue light.
In conclusion, light wavelength had a significant influence on production of mycelia, adenosine, and cordycepin, so lightening wavelength should be changed according to target products in the liquid culture of C. militaris.
Can't exactly explain the red light for mycelium growth but maybe it just tends to surface above ground in grassland pretty much without a lot of sunlight filtering. But cordycepin i believe is thought to be produced to kill the caterpillar, then it would still be a bit buried / in underbrush?
I suspect these things may be categorically linked to life cycle / habitat conditions over time.
Seems difficult but cool to try and imagine the natural habitat of the species you grow and apply it to light spectrum as well as substrate.

Anyone every try shortening the light cycle from 24hrs? I've done this with cannabis and it works well. Instead of running 12/12, I ran 10/10 and shortened my fruiting time by ~20%. Essentially I would shorten a "day" from 24 to 20 hours. I wonder if this would have the same effect on shrooms?

 OK SO, how the crap are you getting such a crazy pinset out of galindoi?! I only grew it out so I could print it for freebies but I was getting like 20 prints total per shoebox. That one flush of yours is like 4 full shoebox lifecycles worth of caps. And you aren't getting the rats nest of curly stipes like I used to with just 6500k. Is it a clone? Maybe my chosen culture is just crap, I have put minimal effort into this species.

With galindoi I never get good pinsets. Here are the 2 galindoi projects I have fruiting right now, already harvested about 20 fruits for printing. This is an isolate that makes great stones fast, like 6 days from inoc
Those other pics are from a tamp isolate . Although from my discussion w cron, galindoi has recently been determined to be tampanesis in the PCR work allan Rockefeller has been doing
Here is my current galindoi and some bags exactly 1 mo old (quick stone isolate, same one fruiting) , and some jars of same culture about 3 weeks old. Bag stones are HUGE
All of these pics are the same galindoi "quick stones" isolate, also showing my lighting setup

Interesting thread! Since melatonin, serotonin, and psilocybin are all based on tryptophan, it could be that light affects fungal metabolism. We already know that oxygen and temperature play a role, and that our own metabolism changes dramatically when we sleep re: tryptophan building.
Red light might help with vegetative growth, blue light with pinning. Blue light may be slightly irritating like harsh brightness of daylight, which is mostly blue. I've seen blue LED arrays advertised for seasonal affective disorder, mouth germ killing, wound sanitizing, etc.
I use a high-power 660/850 nm red/infrared LED array to heal scars. It causes mitochondria to make ATP at a faster rate. Good LEDs cost money. My red/infrared LED array cost $300, for example, and it's about the most powerful one available outside military, aerospace, etc.
If money weren't an issue, I'd use high-power red and blue LED arrays together on a reverse pomodoro schedule (25 min off, 5 min on; 25 min off, 10 min on). Along with a quality full-spectrum anti-depression light on steady for at least 12 hours a day. This last paragraph costs like $1,000 minimum.
Anyway, I keep a special stash of posts around for times like this. Lots of homeboys in this thread.

blue is 450nm , red is 680 nm.
LED is more advanced now than most realize. my entire house is LED , and my entire grow has been LED for several yrs now....... i would quit before i used other lights again. and that goes for cacti and fungi.
alot of the conjecture here is comical to those of us with heavy LED experience.

Here's a quick mockup of what I'm talking about. This is about $425 worth of LEDs, and a good blue LED array would cost $200 more. If I were to build a lighted incubation room at scale, I'd leave out dedicated blue LEDs and spend the money on fans. At this power, LEDs give off quite a bit of heat. Keeping the circuits cool greatly extends the diodes' lifetimes.

I did an experiment with a prolifically fruiting tamp isolate. Usually I give them lots of light to get fully developed caps and a good pinset and vertical growth
This time I used low light after getting a good pinset, opaque lid, to keep them from developing and maturing, to see how long they would get
Well, they grew to over 12"!

WTF?!
You discovered Psilocybe spaghettii
Incredible isolate! I have an ATL7 stone clone that puts out pins like mad but not half as good as your tamp isolate 
I wonder what about low light affected them in that way.

Lol here is the same isolate w normal light. I noticed the fruits keep growing and never mature without good light, so i put an opaque lid on after i got a good pinset, just as an experiment. Got crazy lol

60/20/10 straw/manure/mdma substrate, flashing lights, dj tiesto, definitely worth investigating.
Maybe add a disco ball at fruiting

Hey guys !
I was so excited to participate to this thread 
I finally received my Blue led : ABI 23W Tuna Blue LED Bulb Coral Reef Optimized Spectrum 11-Band PAR38
- 15 bright high efficiency LED chips use a true 23W of power. An integrated ball-bearing fan quietly cools allowing for the higher power. Fits a standard household E26 socket. 100-240V AC input.
- LEDs: 1x 395-400nm, 1x 410-420nm, 2x 420-430nm, 1x 430-440nm, 2x 440-450nm, 2x 450-460nm, 2x 460-470nm, 1x 470-475nm, 1x 490-495nm, 1x 6500K, 1x cyan (phosphor based)
And my Fluorescent Full spectrum : EXO Terra Repti-glo 2.0 compact fluorescent Full Spectrum Terrarium lampe, 26 watts, Whites & Tans
- The Exo Terra Natural Light is a full spectrum daylight bulb with a very high visual light output and high color rendering index (98 CRI). With its high visual light output and 6700 K Color temperature
Here are some pictures of Pan Bisporus and Semperviva :
From the Fluorescent Full spectrum light

From the blue led

Side by side comparison full spectrum vs blue led

Cap from the blue led

Semperviva tray under the blue light

Thoughts from the blue led :
- Seems to help pinning
- Seems to help grow the caps bigger
- Seems to make the fruit shorter
- Seems to create malformation (from the semperviva)
This is far from a scientific approach as too many variables are in play. To be noted :
- These are iso from MS, not clone
- The lights are both around 10 cm on top of the monotubs (maybe it's too close from the trays, causing the malformations ?)
- The 2 monotubs are almost side by side (each one of them benefited a little from the other light
- I'm in Canada, where it was still snowing last week : The results might very well be exacerbated from the coldness

thats really cool Aendir!! nice work, beautiful stuff
little update on my light deprived tamp isolate project, shit got crazy in the 3rd flush! this is the same isolate as all the pictures above, only difference is the lighting and late flush. i knew they wouldnt make mature caps without good light, and that they get long and curly, so i tried to maximize that and got this craziness.
one fruit weighed 9.8g wet, 1.2 g dry, about 15 fruits over 12" , about 5x as thick as the last flush

I was so excited to participate to this thread 
I finally received my Blue led : ABI 23W Tuna Blue LED Bulb Coral Reef Optimized Spectrum 11-Band PAR38
- 15 bright high efficiency LED chips use a true 23W of power. An integrated ball-bearing fan quietly cools allowing for the higher power. Fits a standard household E26 socket. 100-240V AC input.
- LEDs: 1x 395-400nm, 1x 410-420nm, 2x 420-430nm, 1x 430-440nm, 2x 440-450nm, 2x 450-460nm, 2x 460-470nm, 1x 470-475nm, 1x 490-495nm, 1x 6500K, 1x cyan (phosphor based)
And my Fluorescent Full spectrum : EXO Terra Repti-glo 2.0 compact fluorescent Full Spectrum Terrarium lampe, 26 watts, Whites & Tans
- The Exo Terra Natural Light is a full spectrum daylight bulb with a very high visual light output and high color rendering index (98 CRI). With its high visual light output and 6700 K Color temperature
Here are some pictures of Pan Bisporus and Semperviva :
From the Fluorescent Full spectrum light

From the blue led

Side by side comparison full spectrum vs blue led

Cap from the blue led

Semperviva tray under the blue light

Thoughts from the blue led :
- Seems to help pinning
- Seems to help grow the caps bigger
- Seems to make the fruit shorter
- Seems to create malformation (from the semperviva)
This is far from a scientific approach as too many variables are in play. To be noted :
- These are iso from MS, not clone
- The lights are both around 10 cm on top of the monotubs (maybe it's too close from the trays, causing the malformations ?)
- The 2 monotubs are almost side by side (each one of them benefited a little from the other light
- I'm in Canada, where it was still snowing last week : The results might very well be exacerbated from the coldness
Very interesting stuff. Thank you for posting this.
I have noticed that several species that are close genetically to caerulescens and subtropicales will have a different looking cap with the later flushes. I show some of my old results with an explanation of my claim here. I wonder how much more of an affect could be seen when using different light colors.
I'd love to see what those look like at flush 4 or 5.

cultivators have been experimenting with blue LED for about 20 years. only in the last few years has it become clear how useful it is.
many cultivators still insist on 6500k tube light arrays 12-12 this was understandable when LED was expensive and wimpy powered. now you can get a blue LED light the size of a CD case that can pin entire labs in a daily momentary flash cheaply. better technology has arrived.

what do you mean "pin entire labs in a momentary flash?"

Also wondering what you are referring to when you say "momentary flash". Can you provide an example of the type of lights you are talking about? I am about to purchase some new lights for a fruiting room expansion. Was going to use LED, 6500K, 4 foot, vapour tight fixtures with PVC conduit but perhaps you have a better suggestion. I want to use the best fixtures I can get for the purpose.

cubes only require a good flash of blue in the 420nm range at 10w ft...... so any blue LED array 15w to 30 w turned on and aimed at them will cause effective fruiting. 30W in a walk in closet is more than enough. 60W for a whole bedrom. anything exposed will pin.
i like the indoor outdoor grade yard lighting ones in the royals blue i can find. i think mine are like 60W. when i check the lab a few minits of those things is all thats needed.
LED is cheaper smaller easier more durable lower electric. and i think its been demonstrated in hundreds of threads it pins as good as anything else.
before anyone spends a buck on a tube light, shop and see how much blue LED you can get for same or less.
* solipsis, that light looks blue, looks like alot of pins. its that straight.

???
They obviously dont REQUIRE it, ive had projects pin (well) in complete darkness... and even better with 6500k, ofc.. so as far as i can tell they dont REQUIRE light at all, much less specifically blue light
Maybe what you mean is that a flash of blue light can initiate pinning?
Also, there are lots of other factors involved in pinning (surface conditions, colonization, etc).. have you controlled for any of these factors?
Have you tested isolates in the same conditions with 6500k vs blue leds?
A well researched isolate will pin prolifically in the same conditions like clockwork, are you saying that blue light will make it pin MORE prolifically?
I cant recall seeing clean ms cube spawn that didnt pin
Im really curious about all this, would love to carry out some of these tests, just wanna know what others have already learned

imo pins equal or better to any other light ive tested. with no need to run them for more than moments.
theres quite a few grow threads where people have used them on multi species with canopy effect. it works. try it,its cheap to find out.

Im definitely down to run some controlled experiments. But as easily as cubes pin youd definitely need a control to attribute anything to the light
Im curious, are you referencing the line about a "flash of light" from Stamets in TMC?
I was digging for it and saw RR brought up some of the same points i did

Experiments have been done and even a single flash from a strobe light will induce pinning, so clearly that is not an area worth optimizing.
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. RR

i used tubes from 1978 to 1995 then i used tubes and or LED from 1995 to 2005 then i went all LED in 2006. entire house and lab. ive grown cubes , mexicanas, pans, of all types under LED, with excellent yield. im convinced. people can experiment as they wish. and they should. in my case ,from long experience, im all about LED for all my grows.

im currently using 6500k led tubes and strip lights
Never played with the colored stuff tho

thing is alot of lights work well. in my case id rather devote the power to other parts of the lab. so ive developed a grow style flashing them with 30w+ blue LED.

Flash growing? How curious. How many flashes do they get? And for how long?

i grow in blacked out flight cases in dark closet when i pick i use blue LED for work light. if not picking ill just inspect the op for a minit or so with the blue light.
they get no light other than blue. as said, my flushes are par with anything ive seen or experienced with other lights.

what about the phototropism? Have you ever done any controlled experiments w isolates?
Did you get the idea for flashing from TMC (stamets), as RR mentioned in what i quoted?

i was growing for a few years before stamets book. was growing 20 years before i heard of RR. tried every type of light possible over the decades. early on i used lots of tubes of various color spectra
i began serious agar work when i started in the late 70s. every kind of isolate i could create from any spores i could get of cubes, and exotics.
frankly, i got bored fighting with the lights and realized its easy cheap fast just to spot them every day or so with blue.
cost has never been an object, with me its about heat /electric / space. i know alot of people grow in cold zones. i do not, heat from tubes makes a difference here.

Gotcha, im just wondering have you ever done any controlled experiments with blue or flashed light?
Like comparing the same isolate on the same conditions and sub, using 6500k vs flashed blue leds?

oh ya. most of the 90s was various light experiments. i tested all kinds of isolates strains and species with halides , sodium , LED, flouros. alot of stuff works . after years of all kinds of lights, i just sorta concluded i like LED blue best.
if i couldnt get LED id just use sun. ive seen lab accidents with flouros breaking. its a real problem if ya grow with flouros long enough. also, flouros degrade, and the heat . the sound bothers me from the ballasts.
at one point i had several sattelite grows going , same clones , some flouro some LED.
i suppose i could have experimented more with them . but im not sure how. growers are gonna use what they use i suppose. if i knew what i do now, and if LED was available in the late 70s, id have just used that and been happy.
sometimes i feel stupid looking back over the years spending thousands on lights.
