Improved BRF Tek?
    #22348225 - 10/08/15 12:01 AM (8 years, 3 months ago)

"the basic idea behind the original PF Technique: a mixture of brown rice flour and vermiculite is moistened, then loaded into 1 / 2-pint jars.A thin layer of dry vermiculite is placed over this,followed by a few layers of aluminum foil.The brown rice flour provides a balanced nutrient base for the fungus to colonize,while the vermiculite serves as a reserve for water and helps to create an open,airy structure,allowing the growing cultures to breathe.The jars are then sterilized in a pressure cooker or a boiling water bath.After cooling,the first layer of foil is removed,and the jars are quickly injected with a few milliliter s of a spore solution from a syringe at several points around the circumference of the jar.The top foil layer is replaced,and then the jars are placed in an incubator or a w arm, draft-fr ee spot."

This is from the Psilocybin Mushrooms Handbook and I was wondering if putting the foil back on is good for mycelium growth/protection.  I was also curious if any has any experience with growing the method this book suggests which has you grow the mushrooms directly out of the jar had good harvest's compared to cake-style grows.

"In our “improved”PF Tek,we leave the substrate in the jar,and mushrooms fruit only from the top surface of the jar.This serves a number of purposes.One,it eliminates the need for elaborate and messy tubs of perlite.Instead,the jars are placed into any clear enclosed container,or even a plastic bag,perforated to allow gas exchange.Two,the need for high ambient humidity is reduced,because the top layer of pure vermiculite acts as a casing layer,holding a reservoir of water that the developing fruits can draw upon.Since fruiting is restricted to a horizontal surface,the mushrooms that form retain a much more natural appearance and shape.The original “cake” method,on the other hand,tends to produce fruits of bizarr e shapes and sizes,since they form at random points around the cake. (Since spores are most efficiently dispersed from downward facing gills, most mushrooms use gravity to orient themselves horizontally.If,as in our method,the stipes are already pointing in the right direction,they naturally grow straight and tall.) With the incorporation of a casing layer,the “improved”PF Tek more closely resembles the advanced methods we present later.After you have performed this method once or twice,you will be more than familiar with the basic mushroom life cycle,and ready to move on."

Any experience or advice is much appreciated.

Hey I'm a new grower and new to mushrooming in general I hope to learn as much about mushrooms as I possibly can I may be going to graduate school for mycology in the future, but I'm 27 and need money.  But hell life's right in front of me, nothing to look forward to.  Best of luck to all.

No, no and ummm no. Flawed, incorrect and full of supposition.You need to spend some time researching to understand each individual part of what you are saying. You are not trying to grow plants here.

Or rather try growing some mushrooms like the community has tried and tested to work, and then fiddle with it. :thumbup:

Honestly, is this all from that book?

This, to me, sounds bogus :badidea:, BUT I dont want to discredit something I have never done I feel like that dry verm barrier that was placed between the cake and the top of the lid could have contams present and allowing it to stay on the cake longer than necessary is only going to hurt the growth of myc, if one were to use the method described.

And if you were wanting to put the foil back on top of it this seems to stop any pins from coming to fruition because there will be no FAE..

Thanks for the responses yes I'm going to stick with the cake style I think more mushrooms would have the chance to pin, and I will take the foil off after inoculation and NOT replace it.

Good idea, I would just use a simple SGFC follow the tek exactly and you wont have any problems unless your jars get contaminated.

Check out Violet's Invitro Tek and boddhisata's PF tek.  Both essentially work this way with individual fruiting chambers.

The advantage of keeping them in their initial jars is that they will lose less water due to having less exposed surface area, FC is lower maintenance and less elaborate.

The downside here is:
Can't re-use the jars until production is complete
Side Pinning can be a pain in the ass in those little jars.
The best looking cake grows I have seen pin heavily from the side.  The upward evaporation from the sides of the cakes may create a truly excellent microclimate, and there is increased surface area for fruiting a high nutritional density substrate, which is a good thing.  Just geometrically, I can't imagine a half-pint yielding as much from just the top surface as I have seen excellent cake grows yield from all over the sides and top.


--------------------


I spawned some popcorn casings and had double-overlay cause I didn't put enough hydrogen peroxide in my automated aquarium mister.  I only got one mushroom so I cut off the head part where the seeds fall from and put it in a jar of LC and sprayed it all over a tin of PF cakes I made with gravel, cardboard, and bisquick in my microwave.  I think it will be good cause B+ is so potent.
Triggered yet?

Only a square would say "a cube is a cube."


No, this does not look right...
