Just for the first few hours, its about the trapped steam which transfers heat better than dry air, a principle we make great use of to sterilize grains..

Note - this only happens on the top shelf
Yeah that's what they say. I've never noticed a potency loss at all. If there is one, which no one has actually proven yet, it's so minimal that it's unnoticeable. 24hrs in front of a box fan on high makes the outsides pretty damn dry. Then the dehydrator is required to finish them off.

Bad dehydrator then, as others said the top shelf probably isn't receiving enough air flow. I've made this mistake once, drying soaking wet Serbica in an oven that I didn't open at first, 50Β°C. They turned almost completely black and there was like no potency left. So it definitely can ruin a batch if bad enough.

Hi everyone and Merry Christmas,
I have an agar question. The plates seem to be stalling. Wanted to ask am I doing something wrong. They are in a cake box and at constant 21 C temp and in the dark. I incubated at 30 C for 36 hours and a couple of days after that it started but then stopped seemingly.
This was 10 days ago:

This is today:

So it doesn't seem to be moving along. Maybe a little bit. It's been now 20 days since inoculation.
Should I raise the temp? If so, to what? Or should I just leave it.
Plus these bottom plates are different, seems no contam but I don't get it. Any clue?

I've never had this issue. I've had plates contam, spores on plates not grow at all (rare), and I've had jars stall (usually from hidden contam), but not this.
If you don't get an answer, I'd recommend posting on AGAR ENVY. It's a much more active thread and someone there might know. Take some better pics first, here are some tips: https://www.shroomery.org/forums/showflat.php/Number/27726375#27726375

Bought the plates online, sterile and sealed from a very reputable vendor that has a big lab and produces many kinds of mushrooms industrially.

I think smelly means your process for PCing the agar mix. Or were they pre-poured?
And what's your process for inoculating? You have an SAB? Do you spray ISO alcohol in the SAB then let it sit a few min, wear gloves, spray the gloves with ISO, flame-sterilize your scalpel or loop (OUTSIDE THE SAB and after the ISO dries on your gloves) ?
If your plates were pre-poured, are there any you didn't open? Do they still look OK?

has anyone ever made a large dehydrator out of a gas furnace? i searched for "dehydrator gas furnace" but no results.
it seems like an obvious idea that would work great. - the air coming out of the furnace is 130-140F (almost perfect) - it has technology built in for thermostat control - it has built in safety features - it's designed to be used indoors - there's already a blower fan - it's designed for ducting in mind - they come in various sizes. even a small one like a 60,000 BTU furnace would probably be enough heat to dry 25+ lbs  - inexpensive (compared to a $10,000 industrial dehydrator) - inexpensive to operate (about $3-$12 to operate for 24 hours. would be cheaper if you use a thermostat so it doesn't stay on the whole time).
you could use a bun rack (or several bun racks! ) with wire mesh trays. wrap the whole thing in sheet metal and duct the supply air into the back through a plenum that distributes the hot air evenly across the back surface of the dehydrator.
a typical commercial dehydrator uses 6,000 watts (or 20,000 BTUs). a small gas furnace (60,000 BTU or 80,000 BTU) produces 3-4x that much heat.
what is everyone's thoughts? the only thing i can think of is a problem with static pressure. but you could probably just switch out the blower fan for one that could handle that much static pressure.

60k btu is not a small furnace. I dig the idea though. maybe a shop heater? Sometimes you find them free when people replace them with energy star units to get tax rebates.
Shit even 20k btu is a massive amount of heat. Seeems bonkers but it seems feesible. Venting the exhaust is probably the most important/expensive part but i suppose you could tap into existing exhaust for water heater or furnace. A powered exhaust would make me feel a little better.
Craigslist it up!

 https://www.walmart.com/ip/Mr-Heater-MH60QFAV-QBT-Forced-Air-Propane-Heater-30000-60000-BTU/40042277 if you're talking about a propane powered shop heater, i wouldn't feel safe putting that into some ductwork and pumping it into a closed container. a gas furnace would be much safer because it's designed for that. i'd rather spend the extra money and have the peace of mind knowing that my house wouldn't burn down.
but if you're talking about a 5000 watt electric space heater, then sure that could work. but one problem is that they have auto cut off switches above 110F. so it's hard to pump out hot air constantly. also, anything more than 5000 watts and it starts to get crazy and expensive to use. gas heat is way cheaper than electric heat.

yeah that's another con for using propane. natural gas doesn't have water as a byproduct though, does it?
