| My friend wants ME to design a closet setup, as unqualified as I am, with as little maintenance as possible. I was thinking:
-line the inside of the closet with plastic
-a few plastic slotted shelves that will let air circulate
-an ultrasonic humidifier at the bottom, hooked to a timer of course
-mini garden-misting attachments hooked to the tap through a hose, maybe three of them per bed, rigged to a nice timer to mist a couple times a day
-a fan at the top, blowing air out, rigged to a timer to blow at time when humidification and misting are not taking place
this is where my big question is: this is an apartment, so the air cant be ducted to the outside. Is there some way I could make a dehumidifying chamber that will dry out the air before putting it back in his room? Or will he just have to run a dehumidifier in his place 24-7?

| You seem like you got it bro.....
I guess you could just seal a dehumidifier or a large amount of dessicant inside a large rubbermaid and duct thru that. You definatly don't want high humidity in your apartment.
But the air will only need be exchanged every so often, so over-humidifying your apartment might not be much of a problem. You could set up the dehumidifier on the same timer as the fan so they run as one unit.
If you have an entirely humidified closet and you get the casing moisture right in the first place, I doubt it's necessary to have three automated misters for each bed. No matter how automated you get, you still must give the room SOME time, so that will probably be plenty of time to mist if it needs it (which it might not on an ultrasonic). You might need some way to circulate the humidifiers air in the room like an entrainment system with pvc pipes. There is info on that out there.
also make sure you seal the room very well......weatherstripping under the door or something.

| But then again.........
I think it is easier to have a closet stuffed full of stack rubbermaid beds than to work out the problems of a automated whole-room chamber like that. I mean, a closet set-up is a closet setup right? Make sure to let your friend know the laws of KISS...

|I am putting rubbermaids on these shelves, but they need some way of being humidified, aired, and lit from the top. Thats why I'm going with the "open" setup. I guess I could live with hand-misting for a while, thats as KISS as I'll go. I wish I could make the fan-holes open and close automatically too so there's no air leakage between runtimes.|

| One of the aspects that you want to consider ~IS~, with any totaly enclosed system, with a humidifier running inside it (timer or otherwise) is that a good humidifier will go through a couple gallons of water -- in a day, 2 or 3.
That water vapor will condense on the sidewalls & drip to the bottom. Any warm - moist - enviro ~ is a perfect place for contams to get a foothold & thrive.
So, there has to be some degree of fresh air exchange & a way for excess water vapor ~ and/or ~ moisture to escape. Otherwise, you have a "stagnant" system.
With a closet greenhouse (I posted here - about). No need to line the closet with plastic. You can have a humdifier on the closets upper shelf, feeding down into the greenhouse. Then, create an opening at the bottom of the greenhouse.
That creates a high rh, plus some air exchange & a way for excess moisture to escape.
Just an often overlooked aspect you might want to think about.

Thanks for your suggestion. If this were my setup I'd just go with the greenhouse type thing. Here's the deal: A while back, my friend asked me how much I'd be able to grow out of a closet, "I dunno--a few pounds?" A couple weeks later, he tells me he bet his dad a new car that he could grow five pounds in one month, out of his dad's closet. His dad lives out of town, that is why maintenance is an issue. And if he wins the car, his old car (1999 Grand Prix) is mine. They have enough money for the setup, and the hardest drug his dad does is nicotine, so guess what else... I get to keep the goods after too! I even get to keep the accesories he buys! Oh yeah if he loses this bet, he has to work his dad's farm all summer. Win-win for me!

| Scratch the hose & misting nozzles. No need, if you have a hummer in there w/internal fan.
5 lbs fresh or dry? Starting from what?

| Individual bins with auto air exchange.
In shared greenhouses one tray gets contams they all have it. Especially since you wont be checking on it all the time. I prefer my beds/trays to have seperate enviroments. Stacked rubbermaids w/clear sides, flourescensts running vertical floor to ceiling. Rotate during fruiting.
|Posted by: Mycota Dec 03 02, 10:06 AM GMT|
I disagree about individual bins. Doing so is neither cost effective, nor more sterile than a large room size, or closet sized chamber.
Once you are past the colonization stage, bulk substrates w/top casing are fairly contan resistant. Unless, subjected to some overt nasties. Which, can be avoided, if one applies common sence.
A tiny hepa running on a timer in a closet sized greenhouse, or a larger hepa - running inside a 10 X 12 room size grow chamber, keep comtam's -- way -- way down.
Three or 4 individual tubs = 3 or 4 seperate enviro's - one has to manage - seperatly.
A larger enviro is much simpler to manage & maintain. Plus, more cost effective.
Take a look at the following picture, as an example. Multiple large beds, all sharing the same space. If contam's were any problem. They would not be sharing the same space.

But inside a smaller chamber contams are passed more readily than a huge warehouse. Different trays butted up against each other contams hop on over easy, or at least in my experience. I would rather spend the xtra dough and not lose my whole crop, cause I was trying to save a few bucks.
That would cost even more to lose a whole crop, than a few more tubs. Just my opinion, I'm not saying your wrong, just how things work for me.
Do those type of beds contam often?

|I'd imagine you could hook up some kind of anti-bacterial system in there. If you were growing in Holland commercially or something...Maybe a light mist of peroxide+water every day? Something like that.|

Any decent size grow room, that is set up wisely.
Has POSITIVE PRESSURE filtration. Meaning, the air is HEPA filtered as it is pumped in. The air vent EXIT...... is small.
So, the room is mildly pressurized. Any air escaping ... is going out. Contams cannot flow in against positive air pressure -- flowing out.
Plus, another HEPA is running INSIDE the room.
The set up is double doored, like an air lock.
Humidity is controlled via a internal digital HUMIDISTAT, hooked to a commercial size humidifier, inside the room. The water in it, is treated with H2o2.

| You know, I don't think the dry or wet weight of five pounds was specified, I was assuming dry... but a bet is a bet
I think I'll try for the dry weight, and if I can't do it, I'll fall back on a cheap argument.
So HEPA filters will be OK in the high humidity? Probably just need a little more maintenance? Would a light misting of 10% 3% H2O2 (0.3%) every day be a good idea? Or would it stunt growth too much?
I wouldn't worry about the contams unless I was trying to push three or four flushes. I'm gonna do two and chuck, then lay down more spawn right away for another two. I'm gonna have a bunch of 9er jars ready to replace the spent casings. So hopefully 2 weeks, chuck, 2 more weeks, and BOOM five pounds
Cause its about a hundred 1/2 pints for a pound of dry yield right? I could definitely fit 500 pints of pure rice spawn in a closet, which would yield even better. Using 108 quart jars and (hopefully) three electric pressure cookers for the prep. Knockin it all up with equador clone dextrose, wishing now that I had B+ among my modest collection.
You guys have a lot of good ideas, I appreciate them!

Why the rotation during fruiting?
|Posted by: Fungusmaximus Dec 11 02, 04:22 PM GMT|
Cause w/ lighting running vertically the mushies grow toward the sides and lay on the casing layer this way they will even themselves out.
|Posted by: Mycota Dec 11 02, 04:33 PM GMT|
I suggest lighting ~above~ any substrate container.
Simply because you want your shrooms to grow verticaly, stout & tall.
Hey, it Xmass time. One string of those little cheap outdoor white twinkle type light strings can be rigged to run above each shelf, no sweat & toilet flush easy. One string would do a whole closet sized greenhouse.

| But when you stack containers....
I dont like having any unnecessary items in the chamber... whatever works...
|Posted by: Mycota Dec 11 02, 07:31 PM GMT|
I hear ya. I don't stack mine. So, there is the differance.
Moreover, mine don't have lids on them. Since the air is all filtered, anyway. Whatever works, is right. So long as it works for you. Thats what counts.
