Bulk Mushrooms - Wild Bird Seed Spawned to Horse Manure Mix
Hey all, thought I'd put up a simple little mushroom grow I'm doing with Wild Bird Seed (WBS) and horse manure.
I'm an old hand at growing boomers, and welcome any and all comments, questions, or concerns. I enjoy helping others with their mushroom questions (when I can!).
With these South American spores, I just wanted to see how viable and vibrant they still were. I had 39 vacuum sealed spore prints on foil that are about a year old. Mushroom spores can last many years given proper humidty/temp controls are in place...and minus any light.
I started these South American spores a little over a week ago, and I already have some huge jars of WBS colonizing with fluffy white mycelium. I did have one contam already...noticed some green on the white.
I made a glovebox, sterilized everything (and myself), and scraped a few spores in a few jars of PC'd WB. (PC'd the jars at 15 psi for 90 minutes)...which were originally cooled down for 12 hours after PCing.
The jars won't be completely colonized for several weeks still, even though I have them at about 80 degrees (using a space heater that's serving two functions now).
I'll spawn them to a pasteurized (not sterilized) horse manure mix, and let that re-colonize...then a few weeks after that, take the cover off, and a few weeks after that....mushrooms.
The mushrooms get the moisture for growing by the pasteurized material that's added to the colonized substrate. There is no need for any additional humidity to be added.
Ventilation is achieved by small drilled holes on the sides of the container. A few times a day, I'll take the lid off, and fan the tubs for a minute, then recover, for additional ventilation.
I'll upload some pics in a few hours of what the jars look like.
I've got some great bulk pics from past grows that I'll probably post intermittently throughout this thread. It's sometimes nice to have them to more clearly illustrate certain points.
Again I'm open for questions or comments....and the pics will be coming in the next few hours.

i will be watching intently it
sounds like it should be a good one! =)
sub'd, i just bought a shroom kit in a box , can i use a few kernals of fully colonized rye tocolonize my own jars, and keep doing that forever or do i need to start from spore every time, im going to try making spore prints anyways but this would be faster? thanx
Well it's just a simple bulk grow...only one large tub.

The tub I'll be using is different than last years though, just something I found around the house and it's opaque...which isn't the best for pinning.
Ideally, (IMO) you want a transparent tub, so light can enter to trigger pinning. You don't need much light though, and even the air holes that I've drilled for ventilation work fine for sporadic light.
This grow was merely to test the viability of 1 year-old South American spores. I really half-assed certain parts of this already, although that shouldn't be taken as an indication that this is easy, or that parts of it can be extremely amended.
Growing mushrooms is about sterility when you come right down to it.
IMO, a lack of self, room, and item sterility...and not paying attention to detail...are two of the biggest reasons people fail at growing mushrooms.
I don't wanna sound like a snob though. I mean, I've screwed up a lot along the way. For me, I have to fail a little to learn a lot, and I've done my share of failing...haha.
Just a quick peek at my mini-greenhouse... the small cake in the container is just out of a dunk for 2nd flush...I also have 2 more of the big cakes ready to incubate...Z-strain corn to poo/verm...keeps me bizzy when the herb ain't happenin'...next is gonna be oysters and reishi...)
that's a great question!

I've heard there are also issues with declining genetics with each generation, just like marijuana. The reasoning behind it is beyond me at the moment....the Sour Diesel has my brain set on forgetful.
If you really want to save the genetics of the mushroom strain you're working with (and don't want to work with spore syringes or spore prints), you'll have to learn about working with agar, working with slants, and cloning.

I've got video of the sterilization process that I'll provide a link to in a little bit. I probably shouldn't even show it for fear someone will see a step I did wrong and do it....hehe.
I'll just say this: when soaking your Wild Bird Seed, add either 1/4 cup gardening lime or gypsum. It adds calcium to the mix, which helps balance pH and coats the WBS with a "greasy coating" as Lazlo would say. This greasy coating prevents the WBS from sticking to each other.
I'm experiencing this right now with the WBS I'm working with. I didn't add gardening lime or gypsum to my mix. It's not absolutely necessary, as the pics above prove, but the colonization would be twice that had I used gardening lime or gypsum. I noticed one of the jars had a huge block of colonized WBS that I couldn't break apart by tapping.
These chunks are still viable and very useful, it's just that they make colonizing the rest of the jar harder and less likely...from experience.
BTW, I referenced the name 'Lazlo' early. The tek I learned this method from was prepared by an old-time mushroom grower by the handle Lazlo, who you can find on mycotopia.net or through a google search.
"Lazlo's Wild Bird Seed Tek" is used by MANY people, in one various form or another.
PS...ALSO...I didn't use steaming water to soak the WBS in originally. Heat helps break the seed shell down and absorb water easier.... a step I shouldn't have skipped. It'll decrease colonization times if you do.

Reason: Forgot one thing...
Here's are some of my jars from last year's grow:
Well I decided to not post the sterilization video, because the camera turned almost everything into a blue image. It's an old camera that's been through a lot, so I'm not surprised.
The preparation of the grains, and their subsequent sterilization, are critical steps in getting great results.
Whether I succeeded or failed was often determined by my initial prep of the jars before even bringing spores or Liquid Culture (LC) into the equation.
