Do you guys think that itd be worth it to case some cakes that have gone a flush or 2? i have these 2 cakes that are puttin out a pathetic first flush and i was goina grind em up and maybe do a flat cake or straight verm casing (almost same thing) do you think itd be worth it? maybe ill do it tomorrow

can't hurt to try, might be just what the cake needs to get flushing.

I tried using two ( half pints ) that had already flushed once. I cased them together using straight verm. I waited, and waited, and finally,
I was the proud owner of two medium size mushies.... :0( Thats it. That was my My first casing to. Well, I washed the verm from the casing
and re-cased it. Seems healthy but after that 2 shroom flush, I am not holding my breath :) I have 9 more ( straight verm ) in the works using 1 and 1/2 pints each. These seem to be doing well. After a week I patched all of the spots the mycellia is poking from, and they are now in terrariums #3 #6 #7... Should be interesting :)

What strains did you case :) How do Mexi-Cubes perform if they are cased? (every batch of mexi's i did looked totally different? WTF?) LOL

i'd give the spent cakes a good 24 hr. dunking before crumbling.

I read somewhere where you can use a fully colonized cake to start more cakes by creating a hole in the substrate and then dropping in a bit of a fully-colonized cake into the hole inside of inoculating it. The idea being that the mycelia would just continue growing once in the new jar. Is this a respected tek? Does anyone know more about it or see obvious problems with it? I think I'm being too lazy and don't want to make spore prints.

you could grind the cake into powder and try oldtimer's method.

Thanks, quote....I found the tek after I posted the question. I have a few more questions, though. 1) Have you heard about much success using this tek? 2) Is the dry verm layer still used? I can't work out how it would fit in. If you put it in the jars before steaming, it would fall into the holes when you took out the dowels. But you can't really add the dry verm after, because it's not sterile. So I'm assuming that you don't add it at all. Please correct me if I'm wrong. If you don't add it, would you fill the jar totally with substrate or would you still leave some space at the top? Also, without the dry verm is it safe to take off the tape to encourage growth. Thanks in advance, like I said, I'd like to save myself the extra steps of making prints and syringes if possible.

not really, it's fairly new. but you saw his pics, it obviously can work.


2) Is the dry verm layer still used?

his pics show polyfil in the lids, so no verm. barrier was used. seems that you could also just use lids without holes at all, since no injections are needed.

My buddy has a cake to sacrifice for just such an experiment!!
I will ask him to keep a time line and pass the info on to me for posting.

Piece (of cake)

By Oldtimer (Oldtimer) on Saturday, January 05, 2002 - 05:01 pm:

There is no dry vermiculite used in this method since the entire operation MUST be carried out under a good flowhood or glovebox to maintain sterile conditions. As for using old cakes as inoculants for new jars... I don't advise it. Old cakes will be contaminated with spore, bacteria, etc. from exposure during fruiting and these contams will germinate and grow throughout your new jars... Always use a fresh, sterile jar to create new ones using this technique....

Old cakes may be ground into powder and used to spawn straw beds or you can slice them and make up some layer tek trays...

Good luck to you and happy new year...

you might get away with old cakes if you peeled off the entire old surface, exposing the fresh core of the cake.

By ggg (Ggg) on Saturday, January 05, 2002 - 08:29 pm:

So using an open oven door and cleaning up with lysol/bleach/alcohol ETC won't be safe enough?
I guess it's the contams present on the cake that can't beat the existing myc. that I need to worry about. By carefully peeling the cake I am increasing the chances for a clean seeding?! Or as OT says its the airborne nasties OR both. I'm sure my chances of success will be greatly lowered without the hood or glovebox.
The odds were good that Jimmy was gonna toss the cake in question after his next flush anyway so I'll get him to use the clean oven door tek and seed a jar or two with it. There is nothing gained if nothings ventured!

is it possible to use the S.O.S. tek as a means to continue producing goods after the original cake has run out of nutrients?

By grubworm09 (Grubworm09) on Saturday, December 15, 2001 - 06:45 pm:

so is there another option besides using spores? is it possible to generate another cake from old mycelium to produce another cycle of flushing or does mycelium senescence prevent that?

you could clone the mycellia into dextrose water, grow it out some, the use it to inoculate more substrate.

By grubworm09 (Grubworm09) on Sunday, December 16, 2001 - 10:37 pm:

Hmmm, I know I'm being a bonehead here, but how much mycelium for the honey/sugar tek?

just a few threads, a small chunk is all that's needed. take it from the inside of the cake so it will be contam-free. work in a glovebox.
