Mass substrate cultivation - Straw + Cakes
Bought one large bag of straw from the garden centre, half filled 2 pillow cases with said straw.
Boiled a half pan of water added 2 tablespoons of gypsum ( available from brewers shops )
Submerge one pillow case in the pan and boil for an hour. Beware unless you wash your straw first it will start to stink like shit after 15 minutes. I mean really fucking stink.
Sit the pillow case on a collander on your back step, draining board or whatever and boil t'other.
Once both bags have been pasturised and cooled empty them both into a large heavy duty clear bin bag.
Crush up afew PF cakes in a bag as described in the casing method, add this spawn to the straw and aggitate to spread spawn around.
Press this bag into a large storage box with a lid and leave it somewhere dark to colonize.
I'm actually keeping it at just under 25C , a temperature less favourable to trichoderma. Colonization will still occur just a little slower, I always have several terrariums going so I'm hardley ever in a rush to fruit.
Personally I prefer to incubate at a slightly cooler temperature, most ppl will prolly disagree but thats how I work and I don't suffer failures.
Lemme know if theres anything imparticular you want to know about want looking into, I'm always trying new methods and teks, and doing my best to improve them.

Preparing your cakes to fruit
Step 1
· You will need to prepare your cakes using the PF-tek
· Fill a large pan with cold water
· After consolidation birth your cakes into a bowl scrape off the excess verm
· A healthy cake will have a nice fresh mushroom smell
· Wash the cake under running water and place it in the pan of water
· Repeat step 1 actions 3~5 until all cakes are in the pan
· Soak for 24 hours
Step 2
· Bake several cups of verm in the oven for 60 minutes and allow to cool in oven
· Remove a cake from the pan and once more wash it under running water
· Roll the cake in the baked verm so its covered entirely
· Next place a square of foil adequately sized to allow your cake to sit on it into your PFtek terrarium
· Place your rolled cake onto the foil
· Repeat step 2 actions 2~5 until all cakes are in your PF-tek terrarium
Step 3
· Put the lid on your terrarium and wait for 30 minutes
· Then mist the terrarium and the cakes 4 times or until the verm on the cakes in saturated
· Expect to see growth within 1 week

Growing Mushrooms - making substrate jars and spore syringes
One thing you should know 'verm' is a technical term for vermiculite, lol. This substrate can be used to grow all kinds of mycaelium. If you want to grow Shitakes just substitute the verm with sawdust, you know the kind of stuff you put in rabbit hutches. I've been told that this technique or 'tek' can be used to grow Psilocybe Cubensis, widely known as magic mushrooms. I wouldnt advise this though as thats illegal in ... well pretty much everywhere but if you want to grow some tastey organic mushrooms to go with your fry up , just follow these instructions.
Oh and one more thing, to do the inoculations you will need a spore syringe, just google spore syringe and you'll prolly get what your looking for. Alternatively, buy the mushroom you want to buy from the supermarket , make sure its not a closed cup. Take your shrooms home and sterilize a glass with boiling water and sodium metabisulphate (available from all brewers shops) then drop the shroom gills down into the glass cover with foil and leave it for 3 days or so. Then you will need to boil some water fill up a cup and cover with foil, then chill this in the fridge. Find a 10ml syringe (available from some printer shops to refill ink cartridges) sterilize this in the same way as the glass, you may want to add a little cool water to the sterilizing solution so as not to damage the plastic syringe. Fill the syringe with the chilled sterile water , then remove the shroom from the covered cup and squirt in the sterile water, you may need to scratch the spores from the base of the cup, when all the spores are floating around draw the solution up into the syringe.
Ta-Da home made spore syringe, it sounds complicate dbut when you do it once you'll be able to do it again no probs. Now on the the cake making method.
PF-Tek “Cakes”
Step 1
· Mix together 2 cups of verm to one cup of water in a bowl until all the verm is hydrated and you get a little water collecting tin the bottom of the bowl
· Now add the rice flour bit by bit to get a nice even covering on the verm
· You want this mix to be as fluffy as possible, this is your substrate
Step 2
· Fill 6 large tumblers loosely with the substrate mixture
· Then you need to wipe round the lip of the tumbler to remove any traces of substrate that could be a springboard for any bacteria attempting to infiltrate your colony
· Once the lip is clean add a layer of dry verm and level off
· Now you need to make the lids, tear off an adequately sized strip of foil ( Bacofoil is strongly recommended due its toughness ) the fold this in two to double its strength and tightly fold it over the top of you tumbler
· The double layer will remain on until birthing, to inoculate the tumbler safely you will need to add another singe ply of foil to each glass
Step 3
· To sterilize the tumblers you will need a large pan with a fairly tight fitting lid and a means of getting the glasses out of the water and away from the direct heat on the bottom of the pan ( use whatever you have to hand, I use round steel vegetable steaming platform )
· Some people fold a towel up and cover it in water and put their glasses on top of it, and its just not a real good method
· Give the tumblers 60-90 minutes on full boil for a real good sterilization
Step 4
· Once the glasses have cooled place them in a makeshift glove box
· Shake up your spore syringe vigorously ( drawing a little air in aids this ), then flame sterilize the tip of the needle
· Inside the glove box remove the single ply layer of foil the tumbler and inoculate the substrate at 4 equidistant points, your aim to squirt a uniform amount of solution down the side of the glass with each inoculation
· After inoculating one tumbler replace the foil lid and flame sterilize your needle to avoid cross contamination
· Repeat step 4 actions 3 ~ 4 until all your glasses have been inoculated
Step 5
· Place your inoculated tumblers into your state of the art incubator · Check on the development every few days
· Upon 100% colonization leave the glasses to consolidate for 1 week, the consolidation period is where the Mycelium digests its food and prepares to flush
Once you have a consolidated cake you will need to construct some sort of fruiting chamber known as a terrarium, I'll get onto that in another post. Have fun
