hey so i recently decided to grow some fungus and i read that keeping them warm makes them colonize faster.
So i stuck them in front of this little heater thing i have and left the jars there for like 2 hours and when i checked on them they were really warm.
so I just wanna know if its likely that I killed the spores. anyone have any info on this?

You might of killed em, you really arent suppose to get them above 90. I use a tub in tub, fill the bottom tub with about 10in. of water and get an aquarium heater with an adjustable thermostat and set it at 84. Slide your other tub in so its sittin in the water, put your jars in put the lid on and you are good to go.

thanks man, thats a good idea but i found an even better solution! lol, well for now. I put them in a box, wrapped it in a blanket and just put them in the closet where my pot's growing and its nice and warm in there. but thanks for the advice anyhow, i'll probly see about doing that once i get lots of cakes going as there's not a lot of room left in the closet.

I use This Method for making monotubs now.
I suggest you do the same if you can find the tubs.
Mycelium dies at 106F, dont incubate above 80f, it stops at colonizing at 86F...
If you got colonized grain or PF cakes, spawn them to a 4:1 ratio of spawn to substrate...



SuppliesNeeded:



35 gallon blue tub with locking lid from Sterilite .

I've done much bigger and smaller. This is perfect for me.
To fill this tub, you will need the following:
10 dry pounds of bulk substrate
6 quarts of colonized spawn


Hole drill bit that is 2 inches in diameter.

Piece of cheap plexi-glass that is 12x24 inches.
fits so perfect. It is great.


Roll of gorilla tape. Duct tape will loosen in a wet, humid environment; gorilla tape will not.


Bag of poly-fil .
Poly-fil is a non-organic material not habitable to contaminates.
It provides excellent air exchange and filtration.
I suggest not using tyvek or micropore tape.
Neither is suited for this type of application.

Piece of black 3mil plastic or a black trash bag,
cut to ten inches longer and wider than the bottom of the tub.
The corners can be cut as well to round them a touch.

_______________________________________

TheProcedure:


Stand the tub upright and secure the lid into place.

Mark a rectangle on the lid.
Make it one inch less than the plexi-glass' dimensions all the way around.
So your marking will be a 10x22 inch centered rectangle.

Cut this rectangle out of the center of the lid.
I use a propane torch and a hot knife to cut the plastic out along the marked line.

The plexi-glass should sit on top of the cut-out opening and have
an inch of plastic to support it all the way around.

Remove the protective coating from the plexi-glass on both sides.
Tape the plexi-glass to the top of the lid using your gorilla tape.
You may tape the underside as well if you wish.
Tape the plexi-glass well, having a two inch overhang of tape past the edge of the glass going outward.
The inner edge of the tape may line up perfectly with the edge of
the plastic under the plexi-glass.
So the tape will cover one inch of glass and two inches of plastic all the way around.
The finished product is sleek and effective.

Set the new lid aside so you can make holes in the tub.


Four holes in each of the two longer sides.
Eight holes total in the tub.


The bottom two sit where the bottom of the hole is 4.75 inches from the bottom of the tub.
Each outer side of the holes are 5.5 inches from the outer side of the tub.

The top holes are 6-8 inches directly above the bottom holes.
Putting them each 5.5 inches in from the outer sides.

Hole placement is critical to this working properly.
The substrate has to come right up to the poly-fil so the carbon dioxide can expel
properly from the casing/substrate surface through the bottom holes.
The top holes will allow fresh, poly-fil filtered air to enter the tub and circulate.
This circulation and expulsion is what the mushrooms need to survive.

Drill out the holes with your hole saw bit and clean up the mess.
Drill one hole at a time and do it patiently as to not crack anything.


Wipe out the tub now with vinegar. White distilled.


Now wipe it out with isopropyl rubbing alcohol.
Rub down the inside of the lid too.
Get all of the plastic shavings cleaned up well.
Place the lid on the tub.

Stuff the holes with poly-fil.
You want it roundish on the inside, not all crazy, the outside can be crazy.
To achieve this you put the poly-fil in from the outside --> in.


Remove the lid, mist some isopropyl into the tub, and place the black plastic in the bottom.

Tape it a bit to hold it up on the edges.


Place the lid back on and spray oust all around the tub, and you are ready to go.


Once full with bulk substrate/spawn, leave the tub closed to colonize.
Elevate the tub on milk crates or on a shelf.
Most contaminates are within the bottom foot of the air,
so keep your tub up above that at all times.
Cover the top glass with a towel or whatever to block the light.


Peek through the glass and condensation once every few days to check for cobweb or any other contams.


Once fully colonized, you may case if you wish, or leave it be to flush.
If you case, let it colonize again for a few days before exposing to light.



Keep a fan oscillating in the room the tub sits in, leave it on low and don't point it directly at the tub.
Keep the room temperature around 74-77 degrees, even when the tub is just colonizing.
Never open the tub to mist or whatever, leave it alone.

shrooms grow fast as fuck anyways just keep them at room temp.

all that other stuff is just a waste of time.

really? well they dont seem to be growing fast as fuck for me!
so my main concern is if i killed the spores because then if i did i could start some new jars. does anyone know what temp spores die at? and how long they need to be exposed to it? because i see 0 signs of mycelial growth and its been like 6 days since innoculation.

yeah look up ^...2 posts ago I wrote it dies somewhere around 106F...but dont exceed 80. its not needed.

And 6 days is not very long to see much. Put them somewhere ambient around 75F and forget about them for a couple weeks...does a chick know shes prego in 6 days...not usually... so give them time. how hot did they actually get anyhow? I germed spores that sat in a hot trunk all summer one time no probs...

oh true, didnt even see that
and i dont know because i dont have a thermometer or anything but the jars were warm to the touch
couldn't have been hotter than your trunk in the summer

so i got some myc growth on 2 of my jars. woohoo. looks like i didnt kill all the spores after all! lol

what kind of PC did you use?
