beg to differ, your fruit will be malformed.

if I grow in a clear container, I will get border breaks. It I grow in a container that lets light in at all the same thing will happen. Has is there more evaporation at the sides than at the top? whereas, if I grow in a perftly dark sided container, I get no breaks. Have you any evidence of you assertion?

I just googled "mushroom evaporation" and found this http://www.manitariadirfis.gr/en/the-know-how/cultivation-of-mushrooms
They dont say anything about light. If you feel you need to investigate more be my guest.

they are talkingabout oyster mushrooms, the substrate is subject to drying. I saw nothig there about evaporation being a fruiting trigger. I am interested. I'll find the light studies she I locate my manuals.

I have read about people introducing direct sunlight for 5 minutes to trigger a pinset. That was old tek though. I personally do not use any kind of grow light or light schedule. What is the date on those studies and manuals? I bet they are more than a few years old. If you want me to find some concrete evidence you will have to give me a minute.

Here is a tek i have used and still use. http://www.shroomology.org/topic/8670-6-quart-dub-tub-mist-and-fan-bulk-tek/

the tek uses black plastic liners and explains that light is needed for direction. I contend the light he provides is an essential trigger.

the current thinking with the liner over at the shroomery is that it prevents formation/presence of a high humidity microclimate around the edges of the sub. in monotubs and they (prominent members and TC's RR, concir, notahacker, and Frankhorrigian) assert light is a secondary pinning trigger

The plastic liners are use so they stick to the sub when it shrinks. Otherwise evaporation will occur on the sides and cause side pins. It's about evaporation. Not so much light.
Here is a grow log where the person thought he could put tape over the side pins of a z-tube to stop em from growing or some shit. http://www.shroomology.org/topic/6616-bulk-is-good-bulk-is-great/?hl= tape pins
They explain how they are caused by evaporation not light. Light doesn't really have anything to do with it.

The amount of evap in a 100 percent rh is minimal. The colonized substrate will shrink mostly after pinset. The instances you show are inconclusive. I have exposed semi opaque containers to strong light only at one corner where I got breaks in that region and that region only. Sorry, I've seen too much evidence and too many studies beyond hypothisis without controlled experimentation to believe otherwise.
consider this. The substrate will always shrink. Given that, one should always have side pinning yet a well managed light direction does not let that happen. Were those folks to use clear bags as well as black ones of 2 mills or more I would be more inclined th believe.

I do not, I have a very high degree of control over evaporation and rh, higher than most and I have never seen evidence of evaporation being a trigger at all but more of a strenthener. I have the ability to disrupt microclimates at will and have done so many times in order to discourage contams, I have seen little or any altered pin activity.

Mushroom species requiring light for primordia formation are said to be
photosensitive.
Al-though light is not necessary to induce fructification in all mushrooms (i.e.
Agaricus
brunnescens),
certain spectra have proven to be stimulatory to pinhead initiation and are critical for the normal de-velopment of the fruitbody.
Psilocybe cubensis
and
Pleurofus
ostreatus
are two such
photosensitive
species.
A thorough investigation on the photosensitivity of
Psilocybe
cubensis
can be found in a mas-ter's thesis by E.R. Badham (1 979). His work reinforces the conclusions of
other
researchers work-ing with the Basidiomycetes: more pinheads are
initiated
upon exposure to blue and ultra-violet lightwith distinct peaks at 370, 440 and 460 nanometers. Badham showed
that
light stimulation atthese wavelengths for as little as half a millisecond per day caused primordia to form. In contrast,red, infra-red and green light having wavelengths greater than 510 nanometers were
ineffective.
With this knowledge, the cultivator of photosensitive species can develop initiation strategiesincorporating the influence of light. Ideally a fully colonized substrate should be incubated in totaldarkness and exposed to light only after the mycelium first shows through the casing layer. If thecultivator wants to check the culture without the chance of premature pinning, red light is recom-mended (The proper location and type of
light
is discussed in more detail in Chapter IV).

That literature is as old as shrooms themselves. It's from the 70's. Lots of new developments since then. Cubes do not have chlorophyll for photosynthesis. They do not use photosynthesis to grow. All light does is tell them which way is up. Lack of light will not stop them from pinning or growing. It will only make them look funny. Join this forum if you want to learn more about it. they have new up to date teks. http://www.shroomology.org/index
They can school you on what makes shrooms grow. There are guys on there who have actually studied mycology, so they know their shit.

Note that neither I nor stammets (the leading authority on cubensis among other species) claim that light has anything to do with the actual productive growth of mushrooms, which are not plants. I have been to the site many times and am aware of many conflicts in theory. That a study is old does not necessarily make it invalid. Evaporation theory does not hold up to observation beyond the cursory. With respect to you and those on the site. I will need side by side demonstraions. Again, in jar microclimates where one jar is lightoroofed save at the surface and another with no light protection, all things are equal. Only exposure to light and the side lighted jars invariably pin at the border.
