so i have some more questions:
with the holes in the bottom, is there not a need for dripping tray?
and isn't it hard to keep the moisture level up? seems like the pearlite would dry out quickly.
is there a way to wick water from another container to the pearlite?
are there any alternatives to pearlite? could geolite work?
and what does this do to the humidity of the room the tub sits in? humidity is generally high here already.
a random THC induced idea: what about a living culture of sphagnum? i guess it would acidify the water too much huh?
The water will be held by the perlite, no need for a drip.
Depending on the RH the perlite can remain moist for up to six weeks. My area is super dry and my SGFC stays moist for 10 days.
Lots of things can work other than perlite. The hydroton or geolite in your PMP will work. Could use gravel if you had too.
It will not affect the RH of the room its in.

Ps. Mex, galindoi, tampensis etc all benefit greatly from higher FAE.

so how do you re-hydrate it when it dries out? mist with a spray bottle?
also how much light do pans really need? and why do they need it? surely they are not photosynthesising? i'm fairly handy with a soldering iron, how about an array of blue LEDs? or maybe even UV LEDs?

they derive energy from the light they have a circadian rhythm much like you and i so 12 on 12 off, blue led's is not what is meant by the blue spectrum, the spectrum is actually more white to our eyes, just a daylight bulb nothing fancy

so high CRI? warm white over cool white? or the other way around?

6500k seems to be ideal....or a bright window

i have the bright window, but i fear that will make any mushrooms grow sideways unless i darken the sides of the tub.
how much lux/lumen do i need?

there not plants so lux and lumens don't really matter, don't worry about what direction they grow either light only plays one part of that

ok so then the window light should be fine. i have some spots in my house that will work. failing that, i could use some of these: http://www.ebay.com/itm/Cree-XP-G-XPG-R5-5w-Cool-White-6000-6500k-LED-Emitter-chip-With-20mm-star-Base-/221476572840?hash=item3391084ea8
so without the lamp there is the issue of not having the heat on top to create the drafts n stuff. what happens when the heat source is beneath the tub?

The lamps we use are simple, florcesent. CFLs work fine. They produce virtually no heat.
But what heat source are you talking about? What is your room temp that you need extra heat?
I think you are thinking too complicated man. Simple is good in this hobby~!

well i was looking at this guide: http://www.mushroomvideos.com/Terrarium-Tek
and it mentions that a lamp over the tub causes the air on top the heat up causing a pressure differential that causes upward drafts and sets the whole air circulation principle in motion.
(does that make sense btw? wouldn't the hot air tend to rise?)
the room i have the tub in is currently around 20C and i expect it to drop as low as 18C by day and even lower by night. i read that pans are more sensitive to temp so i am thinking of using an IR heat mat beneath the tub. this would basically reverse the air temperature situation.

No, don't use the heat mat even on the lower end your temps are perfect
SGFC is about as simple as it gets. Mist 3-5 times a day, fan after misting for a few seconds. Keep it elevated up at the corners (I use mason jars). 6500K CFL bulb in regular lamp fixture
If your cakes look dry, mist them.

yeah see that's what i loved about the PMP, i didn't have to do jack 5 times a day.
and isn't the SGFC supposed to not need fanning and misting?
also about the temps, this page: http://www.shroomery.org/8698/Panaeolus-cyanescens-growth-parameters shows much higher fruiting temps then that.
is this info outdated?

A pmp still requires misting and fanning of the cakes for optimal results.....

No, they DO require misting/fanning....
We mist the cakes to replace lost moisture from evaporation, which happens to be a main pinning trigger.
We fan out the chamber after misting for a drop in humidity, to make room in the air for the water we just misted to evaporate...
You want constant evaporation at the surface of the substrate....

You will need to mist and fan your cubes. I wouldn't mist pans. If your worried about temps being too low for pans then heat the room not the chamber.

heating the room? lol you must not pay the bill at your house...
as for fruiting temp, i have an old document saying one thing, and a contemporary post saying something significantly different. so what is the correct temp?
and why would i fan cubes when they have a lower FAE requirement then pans, and i don't fan the pans?
and do i understand correctly that the one flaw of the PMP is the lack of FAE?

OMG YOUR WAY OVER THINKING THIS! pans will fruit in the 70's no problem and heating the chamber causes lots of problems, pmp's biggest problems are a lack of fae and a constantly high rh, myc likes some flucuation in rh, that info section is a general info section...it also says .. SPAWN:rye grain , but you can use cakes if wanted

I'm the only one that pays bills in my house, and I live in Canada. Figure that out.

Not the old document. . .

Fanning is not FAE. Fanning is to start evaporation, which is why we do it only after misting. I wouldn't mist pans, so I wouldn't fan them either.

If you don't have one built yet they are also more costly to build than a SGFC. Like cron said a constantly saturated RH is not good. Tho the poor FAE alone is reason enough to me to not bother with one. . .
You seem pretty argumentative for someone who needs help. I will stop helping at this point. Cron, PF, he is all yours . . .
