I was wondering what everyone considered their favorite substrate to use as spawn on to straw and why is it your favorite? A foaf needs to get prepared for his first try at this. He needs a good contam resistant tek.

Popcorn seems popular but I hear good things about rye and WBS.

your gonna get as many answers to this question as JLO has ex husbands. everyone has a diff reason why one strain is rad and the others suck ass. i personally like wbs, its slower to colonize but is cheap and has always treated me good. ive tried rye berries before with total success also, as well as popcorn, which i personally didnt care for.

in reality you can use any of them with pretty much the same resultes imho. you can even do brf jars, and just break the cakes up into the straw.

mixing anything with straw should give you good results. how did you decide to do the straw? log, casing, LB tek?

Not a many people use popcorn compared to wild bird seed or rye, is what I have noticed.
I have used rye berries and wbs (wild bird seed) recently and had no problems. I am pretty much an intermediate mushroom grower and have had no problems moving from PF cakes to grains, the only problems I ran into is overlay on casings.
I have avoided most problems because I read alot before I try a new tek and I follow the instructions to the dot. Expecially concerning sterilizing myself and the worksite.

i have been very happy with rye grass... RR's tek is very simple, i personally use a little less water though, i use 1/2c to the 1.25c of rye seed... only thing is it requires lime and gypsum.. which can be tricky to find in some areas... 50lb bag of rye grass is only like $10 though...takes longer to clonize b/c there is more surface area to cover then with popcorn or rye... streaches about 4x further then popcorn when used for spawn or g2g.
alot of people seem to really like rye berries... i personally have never tryed them... but i have heard good things... seems like it colonizes as quick as popcorn... but not as readily available to everybody
WBS seems about like rye grass... some people seem to have problems with water content... which can bread bacteria... longer colonization times.. but many more innc. points then popcorn or rye..
popcorn is nice b/c it colonizes quickly and is cheap... there seem to be some problems getting the water content right some times... which can lead to bateria contams... when broken up for for spawning alot of bair kernal gets exposed which can open the dor to contams..
hope these helped :)

the search function doesn't work on the archives anymore


the search engine here can search the archives we exported over from discus,
but it's true that the search engine on the discus board is temporarily disabled.
one can still find the needed info by following the logical chain of topics/sub-topics there

don't over look crumbled/powdered brf [pf] cakes,
they are very easy, highly resistant to contams [more than any grain]
and once finely powdered will go as far as any grain.
they make good spawn for straw, too.

So far the bird seed has treated me best when spawned to straw. Once I used pre-sterlized rye berries from some site with moderate success, and am waiting to try again with dried berries myself, but availabity is a problem. I'm getting ready to try my first rye grass to rye grass G2G soon, I'll probally share my success or failure soon. Let's hope success.

your right hipp.. i completely forgot about PF cakes
one of the OG mycotopia memebers
name OldTimer... seemed very pleased using ground up BRF to spawn straw, matter of fact he swore by them... and i'd immagine that a ground up PF cake could create a LOT of innculation points, cheap and also much more contam resistant then grains... but it does require the extra step of grinding..
i tryed them a few times with now luck.. but looking back it could have been a number of things other then the spawn...

For spawning to straw, my first choice would be rye grass seed. The kernels are small enough that they recover very fast from the damage of spawning. That makes them more contamination resistant. There are enough kernels to give lots of points of inoculation, and a quart jar of rye grass seed will colonize in 14 days or so, have nearly twice as much mycelium as rye berries, and probably ten times as much mycelium as popcorn.

^^^^ thanks :)
i've been very happy with rye grass fallowing your tek... i normaly spawn 1qt of rye grass to a 9X13x2.5 pan of straw and poo, i'm sure i could streach it alot further but i get 100% in 5 days... it covers so quick contams never have a chance... haven't lost a tray yet :)... no boil.. no soke, no simmer... just measure your jars.. add water and shake... put on lids and filters and your ready to go :) thanks RR

Id personally go with a 50/50 WBS/Popcorn by volume. You get alot more inoculation points than plain corn, and a much faster colonization than WBS.

Has anyone tried adding a bit of poo and/or straw to their spawn to "train" the myc?

Is there a signifcant speed increase?

With Cubensis, it's probably best to keep bulk substrates and grains seperate.
I've seen it done before when cultivating Panaeolus species...Trops or Cyanescens.

The reason for this is that Pans are usually fruited on a bulk substrate like straw or manure.
Cubs fruit on grains or bulk subs...By adding Poo with PF jars, Pans get a head start ...
like you said, it gets them used to it. I've tried the recipe below, and honestly
it didn't work any better then straight BRF and verm.

Here is a substrate recipe some growers use.....

5 cups of vermiculite
3 cups manure
10 tablespoons of brown rice flour
2 cups of water

This will make 10-12 half pint jars of substrate.

The idea for training is to give the myc growing in your spawn jars a taste of their future substrate . This does not nessessarily speed the growth in the jars but provides an instant "leap off" onto the substrate.
I ran 3 parallel tests with three strains and found pinning occured 2-3days ahead of the non spiked jars...This idea originated with P. Stamets --Its a good'n...
You only need a pinch in each jar...

Evening! I'm going to be doing a lot of oven bag spawning in the next while, and am curious as to the lower acceptable ratio of spawn to material. I have a dozen 125ml jars and four 500ml(400 full) wbs ready for spawning that were all spore-inoculated. To spawn into, I've 3 500's of popcorn, 8 brf, and 6 wbs with more coming. I'd like to make a lot of bags, in the 6L volume area. I was thinking to use some 125's to spawn the 8 brf's and make invitros of them, but now I'm thinking more to making bags.

I've just spawned a bag with 800ml of wbs spawn into 5.6L of combined PC'd wbs, verm & coir. That's a 1:7 ratio. I've found that popcorn jars work very well with a 1:6 ratio (ran out of glovebox space). The Q is, assuming that the contam threat is low due to PC'd materials & a glovebox, how low can I go with spawn? Could I get away with a 1:14 ratio..? That would have me making a 6L bag with one 500ml jar!

(feel the greed, eh? does bulk do this to people?)
