How much heat is produced?
    #6805239 - 04/18/07 04:52 PM (17 years, 8 months ago)

I'm curious if anyone here has recorded the ambient vs. fungal culture temperatures (casing, dung, whatever) over the course of colonization and fruiting.

It occurred to me that one might use a thermocouple or peltier/seebeck junction to capture some of the heat energy (infrared radiation, i presume) to induce a current and run something like a small fan for better air circulation or whatnot.

With some of those Atmel chips running on nanoamperes of current, one could conceivably run a microprocessor off the heat produced. Leads me to the thought, could we embed fungus into a robot as a low-power source? Could you train a fungus to induce currents in embedded electrodes to control servos or whathaveyou if you gave it some type of positive reinforcement?

Sounds wacky, I know but sometimes those are the best ideas.

I've scanned my crops and colonizing jars and substrate bags with an IR camera and noticed up to five degree F increase in quart jars of rye, and up to a 15F degree increase over ambient when shooting at large gusseted spawn bags, but that was 15F over ambient at the edge of the bag. I'm sure the center was hotter. I usually have up to 200 spawn bags colonizing at any given time on shelves in my grow room, and I never heat it, even in the coldest months of winter. The temperature in the room rarely drops below 75F, even when it's freezing outdoors. We use minimal heat in the rest of the condo as well, simply leaving the growroom door open is enough to supply most of the heat we use.

I haven't turned the central heating system on since I moved into this place. In fact, if I wasn't planning to sell the darn thing soon, I'd rob the blower off the unit to build a bigger flowhood.

I've measured half pint jars and found a consistent 2 degree increase at the center of the jars. I've heard of dung/straw reaching temps 10-15 degrees higher than ambient.

12 quart trays of h/poo or compost substrate, spawned @ 25% rate with wbs/grain spawn, will generate 15 degree's over ambient 2 or 3 days after spawning & until about 7th or 8th day of incubation. Multiple times, I have had to kick the air/con on to cool the room. Otherwise, they would have generated enough heat, to begin fermentation & cooked themselves into useless poo/goo.

Poo/goo is NOT a pleasant thing.
Although, it has a rather sickly sweet odor about it.

anyone aware of any emperical evidence of an increase in temp being an indicator that optimal colonization of a bulk substrate has been reached .

roger. i like the idea of hanging bags of colonizing substrate around the house being used as a form of central heating :thumbup:

Roger: Love the heating thing, especially where you live! Have a neighbor that uses attached greenhouse the same way -

Agar: I concur - I think the poo/goo thing is my biggest poo peeve and it seems to happen to me a lot, but I am in a hotter climate and haven't cooled the room except in heat extremes.

What next agar marketing the smell of poo goo for a mens body spray?:) and the wheels turn... That is sweet about the natural energy your producing RR. I have yet to delve into spawn bags and just did my first bit of poo so I'm just learning about the ambient heating of bags and such.
