Frank's Bulk Spawning Tek (in a monotub) * 36
    #17447797 - 12/26/12 04:00 AM (10 years, 1 month ago)

This is part of my series on how I get things done. I hope it helps!

Once your spawn jars are fully colonized, you can scratch your butt while you inoculate the coir if you want.




I will be using 11 quart jars of substrate I pasteurized using my pasteurization tek.
I will be using 7 quart jars of fully colonized WBS I prepped using my WBS tek.
This fills my 18gal monotubs up to the 3" mark, which I find is perfect. You can use a deeper substrate but I find 3" substrates perform as well as 4".

Let's clear one thing up right away:

RogerRabbit said:
When it comes to spawning a bulk substrate, who gives a shit if you pick your nose while working?  It doesn't matter.  If the grains were properly prepared and colonized in sterile conditions to full colonization, you can spawn to bulk outdoors if you want to.  When you go to the Stamets seminars, you'll see Paul build a straw log or other project outside in the open air and it works fine.  However, you can bet your ass the spawn wasn't produced outdoors in the open air.




If your grain spawn is clean and fully colonized and you have properly pasteurized your substrate, you will not see a contam before the first flush.

Therefore, I spawn in open air with minimal precautions. I put on a pair of disposable gloves (non-sterile) and that is that. You can spawn clothed or you can spawn naked, it doesn't matter. No lysol, no oust, no extra cleaning beyond the usual that gets done once or twice a week in my house. I turn off the fans in the room but even that is unnecessary :thumbup:

I should mention that if you use the bucket tek, it is possible that you will see a contam before the first flush even though your spawn was clean. I never trust the bucket tek, since I live in a house with many pets and have had contam problems in the past.


First, wash the monotub out with warm soapy water. I wipe down the sides and bottom and lid. I also wipe down the outside. Dry it off with clean paper towels.

I line the inside of my tubs to prevent side pinning. Some will argue whether side pinning is acceptable or not, but I've found it's a real PITA for harvesting without ripping chunks from the substrate. Even when cutting at the base (which I recommend), side pins make everything messy.

I use thick plastic sheeting found in the paint section of any hardware store. I like a thick liner (3.5mil usually) to prevent tears.

Cut your liner to shape and place it in the tub. Make sure to use extra so you can mix your substrate up without spilling any. You'll be able to trim it after spawning.


I put my duct tape on the bottom holes of the mono and use it to hold the liner in place while working.


Take your colonized spawn jars, check for visible problems and break each one up. Pound it on something with a little give- I use the carpet, RR uses a bike tire.


Open each one and give it a good smell to make sure it is clean.
MAKE ABSOLUTELY SURE YOU SMELL EACH AND EVERY JAR OF SPAWN BEFORE DOING ANYTHING ELSE. This is the most important part.
You will not always be able to ID contaminants visually by inspecting the spawn jars. You will always be able to smell a problem though.
If it smells like ANYTHING except fresh mushrooms, DO NOT USE THE JAR. Toss it. Common smells that indicate contamination include the smell of dirt, a sour smell, a sickly sweet smell, and/or a disgusting smell.

After smelling your jars, we will re-hydrate the grains before spawning. This improves the yield and quality of the fruits, and provides a quicker colonizing time.

How to do it the quick way:

I take a roll of fiberglass screen (the kind used in window screens) and cut a piece to fit around the top of a five gallon bucket.

Grab the five gallon bucket and clean it out. 

Break up your spawn jars and give each a good smell to make sure it is clean.

Dump the contents of each clean jar into the bucket and fill with enough cold water (not distilled) to cover the grains.


Attach the house screen with a rubber band and let it soak for 10 to 20 minutes.


When the time is up, secure the screen with your hand around the edges and tilt until the water pours out. It will drain very quickly, tapering down to a small stream after 10-20 seconds.


How to do it the other way:

Fill each jar with cold water (not distilled). Let it soak for 10 to 20 minutes.


Drain by placing the lid over the top and leaving a gap between the lip of the jar and your lid. Drain it well. The grains will be quite wet at this point.


For spawning my tubs, I layer my substrate and spawn, then mix it. This way I can minimize how much time I spend turning the substrate before it is evenly mixed.

Some will argue that layering is more ideal, but I disagree. Mixing evenly gives much speedier colonization, which is always a plus.



Start by dumping in half of the pasteurized substrate. Spread it evenly.


Pour all of the grains into the tub and gently spread them.

Jars used for dunking:


Bag used for dunking:


Pour the rest of your substrate on top and even it out.


Now get down there and mix it all together. Make sure to get the corners and then even it out as best you can. It doesn't need to be perfectly level but it doesn't hurt to try :shrug:


Don't use a top layer to cover the grains. It's pointless for cubes and only serves to extend your colonization times.

Cut the liner down to size. You don't want to have any of it hanging over the top of the substrate or covering the bottom holes.


If you haven't already, duct tape your bottom and top holes for colonizing. GE is provided by the lid of the tub.


Put the lid on, label and date with species/variety and let it colonize in a 70-75 degree room with minimal air movement.


Bulk substrates produce a lot of heat while colonizing so you won't want your room temps to get above 80 for any reason.

Depending on your spawn to substrate ratio, colonization should be finished in 7-21 days :thumbup:

Ready to fruit? Here's how I stuff my monos with polyfill for fruiting.


:cheers:

When in doubt, throw it out. It should only smell like fresh mushrooms :thumbup:

I bet that's fine, we all have different definitions of sweet fruitiness smell. But i understand what you mean.

I guess some people might find it sweet, but to me it smells like fresh mushrooms and nothing else.
Earthy is usually the smell I associate with dirt and trich.
I don't risk a jar that smells like anything else but the fresh shroomies of whatever species I'm growing :shrug:

It makes sense, fresh oyster mushrooms smell differently than cubes for sure.
I've only smelled kings and the smell was much sweeter than cubes (the kings taste better too :crazy2: ) :thumbup:

Haha.  Same here.  I messed up on one of my tubs cause i kinda rushed it and didnt cut close enough. I have the really cheap bags and I left one side a ill long.  At first it was upright but it ended up falling onto the substrate.  Maybe like 2 inches in.  It's had to tell consolidation in that spot cause the condensation othe liner.  Anyone know if this will be a problem or will the myc consolidate fine iN that spot.  I was told to just wait it out and trim it back when I put into fruiting, but I'm just hoping it won't leave that spot uncolonized or even cause for contams.

I had that happen and it colonized in that spot just fine. Do not open it and try to trim it before it's 100%. Wait to trim it. Now I take extra care and make sure the liner is trimmed just right. I still hate that part though.
