Bottom and side pinning w/ lighting questions. Philosophically asked
    #10408789 - 05/27/09 04:43 PM (14 years, 9 months ago)

There is definitely a lot of info on this site about side and bottom pining as well as lighting as a pinning trigger.
   
      Let me see if I have this right: The biggest pinning triggers are FAE, humidity and full colonization. These are the 3 you MUST have. Secondary pinning triggers are light and cold shock.
      So being secondary pinning triggers the shrooms don't have to have these to pin it just helps out with the speed of things?
      If this is true,(from what I have read I believe it is), then even if you line your containers, and all conditions are right then, in retrospect wouldn't bottom and side pinning happen regardless?
      I have side pinning and bottom going on right now Lots on top also :smile:. Side ones I could care less. I used a casing layer on the bottom(which RR says is one of 3 biggest causes of bottom pinning). This is what got me thinking about bottom pinning and started looking it up.
      Just some philosophical questions for some experienced. (This is my first run at bulk)

It's full colonization, fresh air, light and humidity.  Cold shocking doesn't do squat for tropical species like cubes.  It's for cold weather species.

I don't bother with trash bags or anything, side pins are not a problem or issue.  I don't know what the hype is all about. 

Bottom pins are kind of rare for me, since my tubs are dark bottomed and I don't lift/move the cake around so there's no fae either.

Side pins are common for me and not in any way a bother, hassle or issue.

A casing is meant to provide a microclimate to trigger pinning/fruit formation.  So I'm not really sure why I'd want a bottom casing.  Maybe as a water reservoir, but I don't see the point.

Yeah I don't mind side pins and the bottoms don bother me either actually just curious if anyone thought that even in dark bottom containers you still get pinning. you just don't notice it.

The real question I guess is: Is light an absolute necessity for pinning? Can cubes pin without the introduction of light?

bottom pinning usually wont happen unless air can get to the bottom which using a bottom layer will allow.

Side pinning is caused when the substrate shrinks and the small gap maintains extremly high humidity cobined with the fresh air, if you use foil to try and block of light that will even fruther help pinning as foil reflects light.

Pins can form in the dark, but you will get much better performance giving bright light in the daylight range. Also mushrooms are phototropic, they grow toward the light and also has some play in fruitbody development.

At a recent conference paul stamets suggested that mushrooms use radiation from light.

Light anywhere on a substrate will help cause pinning anywhere else on the substrate that conditions are right.  That's why you get side and bottom pinning, even in a colored or lined tub if there's a 'casing layer' incorrectly placed under the substrate.

Some growers also used to put drain holes in bulk substrate trays.  These also led to bottom pinning due to the air admitted.

Thank you very much RR. Different question now what do you think of metabolites as a fungicide for MJ plants?  Here is my full question  http://www.shroomery.org/forums/showflat.php/Number/10409231

Any advice as how to store extra metabolites?
