General quetion about rH, FAE theory when growing.

Id like to think ive been getting a good education on these boards using the Search, but id like a little clarification/human interaction on this one. In regards to fruiting conditions, or more specifically factors that contribute to huge pinsets: I always see "evaporation of moisture off of surface of substrate" as #1 pinning trigger. Now, does this mean that the cake/tray itself is losing moisture, or that moisture from the environment which has collected on the surface evaporates off. Consider these examples. A) a tray is covered with bubble wrap and placed under light. The tray was not misted prior to this. The substrate gives off moisture, creating a microclimate perfect for pinning between the sub and wrap. B) a tray is opened, misted lightly, and fanned several minutes later. Which example best demonstrates the primary pinning trigger? Because the way I see it, if a tray or cake is placed in an environment with constant 99% rH, how will it ever evaporate moisture? I understand that FAE replaces the air, but ive also read that the goal is still to have constant 90+ rH in conjunction with your FAE. So can someone help me out here or am I just rambling?

i'll give this a shot, i think i understand what your saying, the sub is not giving off moisture persay, it's evaporating moisture and the beads of moisture on the surface is the moisture condensating on the surface due to the temp difference from your subs heat it produces, even at 99% rh you can still have great evaporation as long as you got some fae. when we fan it promotes evaporation to start and replaces the stale humid air to make room for more evaporation to happen, so as long as you got evaporation happening you will constantly have 95-100%(guestimated numbers) humidity on the surface of your substrates regardless of the rh in your chamber, i'm running a whack of tubs/trays w/o any chamber at all

Constant FAE means constant evaporation.....which means constantly high humidity.
As long as the humidity is not constantly 100%, there is always room for some evaporation to take place.
In a SGFC we fan after we mist the cakes, for a drop in RH.
In a set and forget monotub we tune the polyfill in to allow for constant evaporation off the substrate.
The heat from the substrate should keep moisture/condensation on the surface.
This moisture will constant evaporate off the sub, if the tub is dialed in correctly.

Thanks for the quick responses, you guys are the best. I see what you mean how if the sub is losing moisture than the air immediately around it becomes saturated. All promoted by air exchange. Practically speaking, this is what im going to do.
I want to put my 100% tray in a chamber directly under 6500k light, with no rH adjustment, but a low cfm fan running 10 min per hour. I will place bubble wrap on the tray and hope that the frequent soft FAE will keep the tray happy through pin formation.
Then, when the pinset has developed, remove the wrap and "turn on" my rH system to the chamber to see it through fruiting. Fans keep the cycle too. Sound right? Im speaking generally because the thing i built is a monstrosity of excess but can hit most any condition if dialed right.

 i would skip the bw, i find it can hinder fae/evaportaion unless you really baby it, i fruited that in open air and will always stand by the more fae the better, just mist when the surface dries up

since they already hit the nail on the head I'll post this anecdote about the SGFC

if you buy a step drill(expensive) you don't really have to worry about cracking the plastic or having to ream the holes to make them look nice and it's super easy to increase the size later, I started off 1/4 now it's cranked up to 3/8 and it's working great aside from a few grains of perlite falling out here and there but it's really no big deal.
I would really love to try out a mono just to say I did it but I get too much harvest as is with my SGFC I have jars of dried shrooms just sitting around. I only grow for the fun of it now so I'm actually trying to go back to cake sized grows and then bigger grows for edibles.

Could you not just put some window screen under your perlite to keep it out of the holes?

Glad i could provide another noob thread to be hijacked. Boom first dick comment. Anyway never tried the SGFC. i guess RR says 3/8 is the way.

I keep my RH mostly at 100%, use nearly No air exchange (since my substrate to air ratio is already very low), and make a goal to lose effectively No moisture from casing layers - succeeding in doing so as such to where I NEVER mist. So how do you explain my rapid 3-day pinning?
I'm positive that evaporation from the substrate is overrated as a pinning trigger.
IME/IMO, from least to most influential:
6. Signs of decreasing availability of water ("evaporation from substrate") - but even that one not so much, lest my cakes wouldn't have such great results when bottom-watering. 5. Light stimulation of the culture (both a sign of potential sunbathing as well as imminent death) 4. Constantly saturation humidity micro-climate suitable for knotting (it's somewhat circumstantial that evaporation from bulk subs provides this) 3. Air exchange (increased availability of oxygen relative to carbon dioxide emitted) 2. Full colonization of substrate (no more food, imminent death) 1. No- or Low-nutrition pinning sites
Hope I didn't forget any.
Why do I believe that the no/low-nutrition pinning sight is the highest priority?
 That's why. The substrate and surface have not been fully colonized, no air exchange has been given, no light has been given (except very indirect ambient room light), no moisture has been lost, and no water was present near the pins to begin with.
Also, because I get FAR better results from straight grains when I use a casing layer, and not just because the grains dry up if directly exposed, because I still get relatively crap results from straight grains in the moisture-retaining conditions of invitro. And I'm not the only one.

Not sure what violets on about but what I will say is ditch the bubble wrap as it honestly has never made much sense to me, i have heard plenty of people talk about it but never seen them post results and just everytime the guys above have posted good results it seems to have been with a casing layer. Which is cheap... and simple...

what have you got against bubble wrap. Iv had great results using wrinkled wax paper in place of bubble wrap. http://

Yeah i decided against the bubble wrap after reading these replies. Its getting plenty of FAE and rH boosts as is so I agree- why bother. Cracked the lid, blotted up some yellow drops with swabs, gave it a good fan and put it in the chamber. The rest is up to Jesus.
